Hello,
I'm looking for a program that uses the built in GPS of the Touch Pro to record a track & then be able to show the time taken to do the track, the time, speed & altitude at various parts of the track, & be able to be overlayed over a satellite image from google maps or other map file.
I can't find anything that does all this. Does anyone know of a software like this?
Thanx
look for trackme. That will do everything your require.
Thanx that looks fairly close to what I wanted, I'm just not sure how well it will work since I want to use it for motor sport but i'll give it a try.
Any other programs out there?
Hi (and Salam) friends,
Since, HD2 has a built-in compass and google maps, I am looking for a qibla direction finder. If there is not any thing out there like this, are there any SDK's available to access the built-in compass ?
I have never done any programming on WinMo, but I am happy to bring out my rusted programming skills, since I used to be a software developer in my other life!
Any ideas ?
Welll the compass has a builtin function to set a destination, and you'll then be able to see the direction to it on the compass.
Failing that, if you need to build your own app, there's no compass API, so some hackery and back engineering would be involved.

The only "inconvenience" to that is to remember the exact GPS coordinates to the destination, i.e. Makkah, Saudi Arabia in this case! Not very handy!

How easy or hard it is to "reverse-engineer" or "hack" into the compass ?
Another quick question, does the HD2 have an internal hardware based compass ?
Wasalaam bro.
I used a proper Qibla direction program on my 3GS in the past - it was quite accurate - I can't say if the one in our HD2's is though - it seemed a bit 'off' to me, but then again there are two types of north so not sure which one our HD2's points to.
As much as I'd love to have a program that does that on my HD2 (and would be willing to pay for it) - simple thing to remember is that no matter where we are in the UK - Point your compass to South-South East (thats half way between south and south east btw ) and you'll be close enough mate
It beats the time I was in nowhere in middlesborough trying to figure out which way to pray according to the Sun! LOL
Not sure I understand why you can't just use the built-in compass. I use googlemaps to find the direction and then align with the green dot. Admittedly the position is lost when you reset the device, but it's not too difficult to remember the degree position (eg. 138 degrees SE).
Your query intrigued me so I figured Id have a crack at it.
For those interested, the Digital Compass (app) is quite simple to use. You just set the "Picked" entries in HKLM\Software\HTC\DigitalCompass and then run \Windows\DigiCompass.exe
I got the coordinates for Kaaba here, and it seems right on Google Maps.
Im not 100% convinced by the accuracy of the compass. It does seem repeatable away from the computer though, so I guess you would just have to spin it around a couple of times to be sure.
Edit: I should add that for me (in the UK) it reckons its SE, not SSE, so you might want to compare it against a more reliable source before using it.

taiseer999, Can you dig a direct link to the application/download. Currently, the website asks for an account, and its in Arabic language, so not really easy for us.
Link to a app usage description page would be much better (ideally in ENG ), so we know what we are getting into.
Both of you are shining stars !

Qibla Direction Finder is simple that can be used to find Kabaa direction for muslim prayer. This app need Compass and Qibla GPS sensor on your android device to calculate the angle of your location to Kabaa position, where the position of Kabaa we get at 21.422523 latitude and 39.826184 longitude from Google Maps.
qibla direction or mecca finder is simple and helpful app for muslims anywhere in the world to find accurate (Kaaba) qibla direction. qibla direction finder is a most accurate qibla direction compass and qibla locator.
!! FUN APPLICATION, NOT INTENDED TO BE USED IN REAL WORLD AVIATION !!
For all those flight-sim enthusiasts out there: I have created this PFD (primary flight display) which shows the speed, the altitude the coards and the attitude similar to a real PFD display in an airplane cockpit.
Although the application has been created and tested on an HTC HD2, it might work on other devices as well. Internel or external GPS and the HTC G-Sensor are required. It is planned to add a serial communication channel to a PC server component which allows to use this little proggy with MS Flight Simulator displaying the flight parameters so you can get rid of the cockpit panel on your primary display.
Just keep in mind that this is the first version of the program, so there might be *some* improvement potential.
A screenshot of the program is also attached.
Pls let me know what you think about it.
Thanks.
As a pilot I cannot find any sense in this, sorry m8.
Useless for aviation.
Useful might be an HSI-App, an RAIM-availability-check-App, a NOTAM-APP and so on. An artificial horizon on a handheld device... No, not good...
Title correction...
It is just for fun, not intended for real world aviation.
I will change the title so that it becomes more clear.
As an airbus pilot I like it! Lots of scope for further development, keep up the good work !
when I read your discrip, I had something totaly dif pictured in my mind. guess Im falling back on my sail plane lesson days.
I had round face dial and a yaw bubble pictured.
While this is cool, I would prefer to see the old analog style with an altimeter that you can set your start altitude and a yaw bubble, rather than the HUD style. just IMO.
And yes this is just for fun.
Keep it up, I will follow your project with intrest.
cheers
Good Work mate
While some are critical in their opinion I'm pleased with your app.
Keep up the good work mate and for all others who are not so encouraging ...... what do you want for an app a full blown flight simulator, the guys making an effort to develop something and sharing it for a free with us so to help him out at least .... I mean at least encourage him and make some constructive criticisms.
It doesn't cost to be nice and help to motivate others...........
Customize it
Just as a hint for those of you, who would want to use other bitmaps. I have designed the application in a way which allows you to modify or extend it. If you look into the applications program folder, you will find an XML file describing the layout of the display. You may also change or add bitmaps. The bitmaps are all located in the
HTML:
resources
subfolder. If you change the size of the offset of bitmaps, you will have to adjust some values in the XML file as well.
As you can see there all items are drawn in 3d space.
However, I am working on a HSI as suggested before. I will post it later this week.
Known issue:
- After running the application 3 or 4 times, OpenGL is not working properly anymore (not able to create rendering context). This is an issue of OpenGL. You have to restart your device for OpenGL to work again. If anyone has a solution, please let me know.

That would be awesome!
Cool app
Certainly would be better than no attitude information in the event of a vacuum and/or elec failure.Even if just to make flying the performance instruments a bit easier.
I would defintely like to see a HSI app possibly with an open (editable)waypoint database.Anyone interested!?
Keep up the good work!
I love it. Thanks so much...
I just wonder if settings could be made permanent until being changed again so as to start the application without my having to select REAL and AVERAGE everytime.
And as a proud HTC HD2 owner, the display could me made much
larger indeed...
Congratulations and thanks again.
This is a fine app with a lot of potential esp. for UL-pilots as an emergency backup if UL-airplane-pfd fails.
Would be nice if indicators are bigger and the layout equals to Flymap, Skymap or MGL-layout
There is enough place for a nice big yaw indicator. Maybe You can get some code from GPS-tracker V2.0 (MooNah) in this forum, it already has a full working PFD incorporated.
Good luck with further devs., when next version is online I will try it in my gyroplane.
I think it's fun!!!!!
next step: build a flightsim for wm where we could use this
You will be in real danger....if you do so.

As you will easily see, this PFD horizon responds to gravity, that is, to the accelerometers installed in the phone.
It has no gyros, no way to provide PITCH ATTITUDE, WHATSOEVER.
If you keep the phone perfectly vertical and quickly move forward (accelerate) it will SURELY show a pitch up...pretty much the same effects that a stand-by compass shows when changing speed (remember that?...accelerate-north, decelerate-south).
You will have the very same pitch information as the one given by a bottle full
af water suspended from a string, or a can of Coke : and it will KILL YOU as well as your passengers (if any), not to mention people on the ground.
The only usable parts of this FUN APP (as named by the author himself ) in aviation are:
1. True track (not magnetic heading).
2. Altitude (neither QNH, nor QFE related, but of course; unless your flying field happens to be at sea level and actual atmosphere matches the ISA atmosphere parameters exactly). Remember that QNH variations as well as heat will make the GPS readings very different to that of your altimeter, as height of the air column will vary a +/-4% every +/-10 degrees Celsius.
Example. Airplane flying at Flight Level 300. QNH in the area 1023. Terrain at 2000 feet. Atmosphere is ISA+15.
Therefore if we move the 1013.25 setting to 1023 there will be a reading increase from 30.000 feet to 30300 (calibrated altitude, QNH related).
That is 28.300 feet above ground (we start with this as the air column height for the calculation). Since ISA is +15 we add 15/10 times 4% and we have 28300*15/10*4/100= 1698. True altitude is 30300+1698=31988
So we are cruising at FL300, 30.000 feet pressure altitude, 30.300 feet calibrated altitude (QNH related), 31988 above sea level, 29988 feet above ground level.
GPS WILL SHOW 31988 FEET.
3. Ground speed ( neither IAS nor CAS nor EAS nor TAS), as provided by GPS system. Remember that your airplane aerodynamics are related to calibrated speeds....you will stall if too slow ore destroy the airframe if to quick !!!! But you can navigate and make good your track, of course.
Hope I have made myself understood....and that you read this at the earlier !!!
Hi!
It quite very good if the second part under we have the route. I am using the Oziexplore program, it can creates the route, and apear on screen. if this soft applied to that once, could be perfected!
Thanks
great app mate..just for fun...
Nice work thank you. On future can you make like pilot cocpit with all dash boards like in Flith simulator game if this possible. Thank you

Indeed as an Ultralight-Gyroplane-Pilot I like this app and since the Horizon-tab in GPS-Tracker by MooNah doesn´t work right now this could be alternative as a a last resort-backup if glass-cockpit instruments (MGL-Avionics) fail ...... (better to have this than nothing at all and I also have Flymap PPC on my HD2 if main Moving map Nav. fails)
This app has great potential since it reads the infos from G-sensor and GPS.
For the future dev. if I might add my wishlist:
1. Add to screen: slide-indicator and compass, Altitude
2. slightly more refined graphics
As a start: BRAVO, hope You have the patience to go on developing this nice app ( like Dunc001, that made in 100s of hours of work a professional weather app - Duncans Weather Panel - see there - that is more reliable than many professional aviation weather briefings).
I bookmarked this thread and hope for further developments by U
Congratulations

Hi,
i created an App called 'MM Tracker' which is able to read QCT maps from Memory Map from SD Card and displays them.
The current GPS position is displayed and tracks can be recorded, saved and (re)loaded.
There is a free version called 'MM Tracker FREE' to test the App on your device.
The free version is just displaying your current position on the map.
All other features can only be used with the full version.
Features are:
Tracks are stored to SD card as GPX files
GPS track will be drawn on map
Track properties can be adapted (color, width and opacity)
Overlay Manager for Tracks, Routes and Waypoints
Waypoints can be created at GPS position or by manual entry of coordinates
Routes can be created
Displays compass on map
Map can rotate in direction of travel or by compass
Pinch zoom
Support for landscape and portrait display
MMI files can be used to search places
New maps at current position can be selected with context menu
Maps with larger/lower scale can be selected with on screen buttons
When leaving the current map a new map will be automatically loaded (when available)
'Lock to GPS' can be enabled to scroll the map while you are moving
'Screen Lock' can be enabled to prevent unwanted touch input
When device is switched off (standby) MM Tracker is still recording tracks
Displays the map scale
Volume buttons can be used to zoom in and out
MM Tracker does not support the new Memory-Map format QC3 / DRM encrypted QCT!
Important:
Due to limitations of the Android NDK currently only maps smaller than 2GB are supported! If the map is bigger than 2GB, the map tiles beyond 2GB will displayed as white tiles.
'MM Tracker' runs on Android 2.1+. For Android 1.6 there is a special version of 'MM Tracker' called 'MM Tracker 16'
The development of 'MM Tracker' is ongoing and new features will be added frequently. Feel free to suggest....
You can find all info about 'MM Tracker' here: http://sites.google.com/site/mmtrackerinfo/
Have fun...
MM Tracker is now available for Android 2.1.
As i only could test it with the SDK emulator, it would be great if you could post some feedback.
Michael
Michael,
thank you very much for releasing MM Tracker. I have downloaded the free version, and it's absolutely brilliant. I would say it works so much better than MemoryMap, since MemoryMap on WM had a problem with maps bigger than 200MB. The 2GB limit that still holds for Android makes things so much easier, in that I don't have to split maps any longer.
A few updates that I would suggest are:
speed vector
ability to read elevation data (*.qed files) and to display the elevation profile of a route or a track.
ability to read mmi data and search for a place by name.
With the above features, MM Tracker would be an ideal replacement for MemoryMap Mobile.
Keep up the good work, Michael...
ccristal
Hi ccristal,
thanks for your feedback.
The speed vector is a feature which i am currently working on. But i am not yet satisfied with the results. So it will be available with one of the next updates.
Rgearding QED and Search-Function... the problem is that i do not know how to read QED and MMI files. So for now this is not possible.
It would be great if anybody could supply a specification of the QED and MMI files
Best regards,
Michael

Well... you were not supposed to know the format of the .qct file either. If you reverse engineered that one, I'm sure you can figure out qed and mmi as well...
EDIT: oops... I just realized that the QCT format is public... but we can still work on the other two. I've just opened a .mmi file with a hex editor, it doesn't seem impossible to decode. Let me investigate some more and I'll let you know...
ccristal
Yep you are right ... QCT is sort of public As you can find various descriptions in the internet it was just about to put them in code.
As far as i know the QED format is similar to the QCT format. Only the tile size differs and maybe some other details. I will check this.
And i had a look into some MMI files. Seems to be very straight forward:
1.Section defines Categories
2.Section: Placenames and coordinates
But details have to be figured out.
If you get some more informations, it would be great if you could let me know.
Best regards,
Michael

GREAT app mapman...
Downgraded to 2.1 as dislike android 2.2..
Works well but occasionally lags a bit when moving fast cross country.
Would like to suggest OSGB grid refs and map rotation to compass direction and a compass too..
With these features it will run circles round Memory map.
Have to say there are a lot of us where am stationed who are very pleased with this app...
Looking forward to future releases and YES will be buying full version in next week or two...

Lohtse
Thanks
Hi MapMan
Thanks for this great app, having been 'forced' to switch recently from an HD2 (WM6.5) to a Desire, I became resigned to the fact that Memory Map appear not to want to support Android this side of the next millennium, so the ability to use my OS maps on my HTC Desire is very welcome indeed. Thanks. !! I switched from the free app to the full version after about 2 mins of evaluation.
The App works well for my basic needs, although as commented above, the ability to see height profiles would be welcome, although in terms of my priority wish list I would welcome the opportunity to :-
1 Accurately create routes on the device - with route properties in Miles and Knots (as well as Km). I would like to be able to create routes and edit route points - perhaps by nudging them with the central optical button. This was a great problem with WM6.5 on my old HD2 where all you could do was move the very small point with a very large finger !, and perhaps in slower time look at the route elevation profile.
2 Whilst its good to see tracks displayed, I can't seem to be able to save them - perhaps I'm doing something wrong.
3 A route arrow - although not a high priority for me.
Overall a great app and given my large investment in paid OS maps, this really is worth every penny. To be honest I would have paid 10 times as much for it. I just hope you don't get hassle from MM. Thanks
Hi lohtse,
congrats, finally you got rid of Android 2.2

As a lot of people were asking for it i have planned to implement some support for OS Grid. But honestly... i think map rotation is not on the "roadmap" of MM Tracker
Today i added the speed vector as a first step. I think compass could be a nice feature too.
Happy tracking,
Michael

Creating routes is definitely a feature i would like to have too. But as it is a little bit of an effort to implement, it will not be realized too early.
Tracks are saved automatically when you close MM Tracker. But you have to define a correct path for the Tracks (the latest update of MM Tracker has a more convenient dialog to choose the directories).
Regards,
Michael
P.S.: Thanks for your suggestion... i was thinking of raising the price too
hi
mapman are you uk based? if so drop me a pm...
So how easy would it be to create an Anquet Maps equivalent?
Knew I should have gone for Memory Maps!!
Hi Map Man,
Your software seems to be very interesting.
I have a winmo 6.5 and I am looking for a new phone. I know there is no solution for the new WP7 and don't like iphone. So I think about Android.
I just want to know if it's possible to import/export waypoints/tacks between Memory Map PC software and your MM tracker.
Thank you.

I think we have the same opinion there
MM Tracker creates and reads tracks as standarized GPX files.
These files can be imported/exported with MM software.
Waypoints are currently not supported, but will be in future.
Best regards,
Michael
Great, Map Man.
Hope you could add waypoints import/export in the near future.
It's the last thing that prevents me to quit my winMo 6.5 for Android

just to make my explanation from before complete:
If you export your route from MemoryMap as GPX-track and load it with MM Tracker, you can at least see the 'route' on the sceen.
Of course navigation to WP/routes is not yet possible, but maybe this helps you...
Regards,
Michael
Hi,
just want to inform you about the latest update V1.1.5
History
Feature Added: Switch between metres, statute and nautical units
Feature Added: Tracking can be started and stopped
Improvement: Status icons in statusline
Fix: ConcurrentAcces to tracklist while loading fixed (was leading to crashes at startup)
I would recommend this update, especially because of the last item in the list
Regards,
Michael
Thanks Michael, this is such a great app! Really look forward to each update, nautical units much appreciated
How easy would it be to implement quilting / auto loading of next map?

great that you like MM Tracker
But what do you mean by "quilting" ?
Auto loading of maps is actually supported. When GPS-lock is on and you leave a map, the map with the best scale which fits to your position will be automatically loaded.
(Currently no support of subdirs, but this will be fixed)

My Samsung Focus only gets GPS position updates once per second (1Hz). At 100kmph (~62mph), you've already moved ~28meters or 91 feet. Thats pretty inaccurate.
Are there any WP7 phones with built-in GPS that update more frequently than 1Hz?
$40 external Bluetooth GPS units update at 10Hz and some wired usb units update even faster than that. But Microsoft isn't supporting the SPP Bluetooth profile even with Mango update and I see no way to communicate with a generic USB device through the micro-usb port cause you don't get native access to write a driver. So no luck getting external GPS working with the current framework
I'd like to build a list of the GPS update frequency of the various phones out there. Hopefully they are not all using the same crappy GPS chip...
10 Hz GPS update will drain your battery much faster... Also, GPS software have some interpolation algorithms. From my own experience with Navigon 3.0: I very like WP7's default GPS accuracy.
Thanks.
I don't care about battery life though; my scenario has power cable available (non-hand-held scenario).
The compass and accelerometer sensors are available on my device but unfortunately the Samsung Focus does not have a gyroscope.
Accelerometer and compass samples at 50Hz, but they are fairly noisy. The new Mango/7.1 Motion API should help filter some of that noise and maybe I could get a reasonably accurate equivalent of a 2Hz GPS with some tricky math.
Double the accuracy is double the accuracy!
BTW, for what kind of tasks you need this accuracy? As I said before, Navigon 3.0 (see corresponding forum) works very fine and precisely, as a standalone Garmin, for example (what is internally also WinCe device ).
I'm not doing GPS maps. Everybody's done that Mine is more of a real-time motion analysis and visualization. I don't want to give away too many details cause I don't want someone to beat me to the punch. I do know that nobody has an app that does what I want on the marketplace yet.

Oh cool. I wonder if mine is set to 1000 impliying 1Hz updates. 500 would be 2Hz updates.
But I reckon when submitting an app to the marketplace you're not allowed to edit the registry
