MyMotion – GPS Tracking in Action

July 30, 2008 2 comments

Well, I put MyMotion through a decent workout on Sunday – tracking my team’s position along a 60 mile bike ride from London to Cambridge. And as you can see, it did pretty well.

Where have you been?!?

Where have you been?!?

I chose to export the routes to KML for now – included in the KMLs are the route – which thanks to my Kaiser’s GPS receiver, seem pretty accurate – and also pushpins for the distance and time intervals I set, which were 0.5km and every 90 seconds. Hopefully, I’ll be able to get more of the instantaneous speed information out by exporting to a more ‘purist’ GPS format, but for now, it’s quite cool being able to retrace the route we took the other day… and it was clear and sunny then, as well.

As for the stability – this has always been a problem, since running reliably for hours on end in the background isn’t something anyone who knows Windows Mobile would expect to happen. For this reason I saved and restarted the logging 3 times. And – two of the runs completed successfully. The middle route stopped half-way through, meaning I lost around 15 miles of the 60 in the middle of the route. Still – not as bad as you would expect. Turning off the Auto-Start/Auto-Stop settings on MyMotion seems to help as well.


WMMiniGPS Review – tryout

Windows Mobile Mini GPS ScreenshotI’ve been looking for a way to standardise the way I record my training runs. I’ve used, and for the London Marathon a few years back I used my wristwatch, checking off mile markers that I’d identified previously on Google Maps.

They both worked reasonably well, but in this age of mobile-phone-does-everything-ness, couldn’t I use my Windows Mobile HTC TYTN II with in-built GPS to track my runs?

Well – yes, and no. I’ve found a great app to datalog the GPS data as I travel – basically, exactly what’s needed. WMMiniGPS is a satisfyingly lightweight app that just logs your GPS feed – that’s all you need, and that’s all it does. It also exports to .GPX and .KML for Google Earth, which is really useful. The screen shows real-time GPS info, including speed and position. Fantastic.

And here’s my run on Google Earth. Looks good, doesn’t it? Unfortunately, it’s just a track – I can’t see any way of drilling down into the data points to read speed and position – I suspect the export simplifies it to just Lat/Long coordinates, and loses the rest. So – my hopes of harnessing whatever statistical analysis tools that are out there for measuring average speed, speed over distance, etc. could be dashed. I’ll have to investigate further.

The other thing is that, of course, you need to leave your mobile on while you’re logging the course – so a change of settings to disable my auto sleep mode, and lock the touchscreen before setting off, were necessary.

Still – potentially, a very useful, simple app; simple, effective, DoesWhatItSaysOnTheTin. Try it out!
