I'm trying to find a GPS module to enable position holding of an autonomous helicopter. The craft can already control its tilt but it gets pushed around by the the slightest breeze.
I've read a few old posts about low cost receivers (sub $200) with position updates >1Hz and I would like to know if anyone is aware of new modules in this category. I would like to use a Sparkfun module with built-in antenna, battery, etc. but I think their update rate will be insufficient for a tight position hold.
A lot of new cellphones are including GPS so there must be some new small, low-cost modules available. Does anyone have more info? The U-Blox 5 series looks interesting but will not be available until sometime '07.
I'm currently planning to use the U-Blox LEA-4M which has a 4 Hz position update.
