Geoff replied to Geoff's discussion MediaTek Mode"That problem is solved. Just needed to bump up the baud rate from my PIC to computer to be equal to or faster than the GPS to PIC so data won't get lost...
Next question, what are the commands to do the following:
1. Change the baud rate
2.…"

I'm testing the the MediaTek GPS module on a project where it is communicating with a dsPIC33F microcontroller.As understand it, some of the units have been flashed with a custom firmware that communicates with a binary protocol. After figuring out that it was communicating at a baud rate of 38400 instead of the expected default of 9600, I was able to read the following:$PGMOD,,,,,,,,,This is followed by about 20 more ,,,,,,,,, 's every second.

"Makes me think we should have a free flight contest, lightest possible GPS logger on a very well made airframe with maybe one AA cell as the power source?
It would be I think, although I stand to be corrected totally outside of regulation.

bGatti commented on Geoff's blog post UAV Altitude Record"This is very interesting - especially as a comparison to the Ardupilot.
The use of xbee instead of transmitter is a much cleaner solution no? here's the catch, its slightly more expensive, especially since you also need a ground station…"

Hi all,
Just wanted to fill you in on a small UAV altitude record that was just set (still unofficial at the moment) using an autopilot similar to the ones discussed here. Here's a story about it: http://news.stanford.edu/news/2009/september14/airplane-self-pilot-091809.html
The record attempt was made by a group of graduate students who took a course this spring in the Aero/Astro Department at Stanford University. I was the teaching assistant for the course. This year the… Continue
