"There are multiple airplanes in each system, four I believe. The $35,000 for each airplane sounds about right, the rest is for GCS, training, spares, etc..."

"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.…"

MediaTek Mode

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. I've left it outside for a while and verified that…See More

"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…"

UAV Altitude Record

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
