Cool app for the Android phones. It's $7 in the Market.

It does GPS data, lap times, split times, Google earth overlays, etc etc.

I think this is worth giving a try.

 

pretty niffty stuff. (I have a android mytouch and looking for a nexus btw.) sorry for thread jacking

 

I have my doubts about the internal GPS receivers being robust enough to make this useful. We had issues with the 20 Hz Racelogic VBox units at times - they needed at least 7 visible satellites to be accurate and even then you were dealing in .05 increments (which is probably sufficient). The satellite visibility could be a major impediment at Pacific due to the elevation and trees.

 

I ran my AIM system off of GPS and it was pretty much spot on with speeds and times in comparison to the AMB system at the track

 

The latitude program in google maps is pretty accurate...sometimes. One time it actually pin-pointed me in the room I was in. Other times, it'll give your location within 50 meters or so.

I've yet to really try the gps-based navigation that they just added. I accidentally left that running once, and blew through my battery in 3.5 hours.

(I've got a G1 running android 2.1).

 

Considering an AIM GPS sensor has features like a diversity antenna and such, I wouldn't expect much of a delta in the results. You are starting with an entirely different cla$$ of hardware.

I would however ASSUME that the GPS receiver in a cellular phone to be far less accurate.

 

What Jerry MEANT to say.....

 

Still a cool app nonetheless...where the hell are the cool apps for Windows Mobile?? I need to pimp my HD2!!!!!

 

The AIM system is fairly similar in concept to the VBox. Except it's not British, which is probably worth something.


GPS datalogging is only as good as:

1) The number of satellites you're able to track
2) The frequency you receive updates from those satellites

A cellphone is probably going to track 3-5 satellites at most, which puts your positional error somewhere around 25-100m. They probably can theoretically track the 7 or 8 which are necessary to get down to 1m accuracy, I just don't see it happening regularly unless you're in a very unobstructed area. At a track like Thunderhill, it will probably work; at Pacific, not so sure.


That said, for $7, it's pretty neat.

 

Probably really far out. The number of Android handsets has surpassed the number of iPhone handsets in the market all while the number of WinMo handsets is still in a rapid decline.

Until WinMo can start getting market share similar to the "the big 2" then I wouldn't get your hopes up. Windows Phone Series 7 (which is a silly name) looks to be a promising platform but we'll see!
