Can anyone confirm that the M1200 can do 5Hz? I just made use of said shipping special.

You might need to send it a command to enable 5hz, but the chipset itself is capable of 5Hz operation. (and as long as you don't lose the battery it should stay at 5hz).

You might also be able to save the options. I think it is the PMTK300 command that sets the rate (200 in milliseconds).

A collection of data someone put together is at:

Sorry for the bump but I am in the position where I can get one of these with my N800. I was wondering what the deal with the 5HZ is?

5Hz (instead of the default 1Hz) will update your location 5 times a second instead of once per second. That may or may not be useful to you, depending on what you need and what application you use. However, 5 Hz will spend the GPS battery somewhat faster.

Oh, is there anyway to switch it to 1hz? I can see it useful for maybe in the city but road trips...no.

You could use the nokia as a head light and camera.

So my brother has been looking into using a GPS unit to do logging of his car racing. It turns out that 5 hz updates are very important for racing. I tried the hack in the OP with my Holux M1000, and I can confirm that it still works with Maemo Mapper post-hack.

Thanks!

Just a note; from what I've read, increasing the update speed reduces the battery life of the GPS unit by about 40%...

At http://nitapps.com/ you can get gps-clockd which will set the clock and provide a log with time to lock. http://FragosTech.com/MaemoMapper has more information on this subject.

Considering there are only 31 GPS sats up currently, and you likely can't see more than 12 at any given moment, and considering there are only 17 Russian GLONASS birds left flying around, and if you could track them you would likely only see 3 or 4, and if this receiver also could do Galileo that is 30 more birds total (when they get launched), 12 at any given time if you are lucky, I think 32 channels is more than enough,
