Dear Agrawal;

I am standing your news.

do you want to cooperation for a autopilot board ?

We are building completely UAV plan and ground station.
We are explore long distance communications systems.

Hi, you still working on the navigation algorithms? I've been doing the exact same research for both bearing and distance, and have found two of each that are very accurate. I'm using a PIC16F877 with a math co processor. I've got the formulas written and working in C right now, but I'll be writing in BASIC. -Jesse

That's great to hear! I think I'd have an easier time if I was to use C for programming the pic. I've only used BASIC to do so. So with the PIC16F chips and BASIC combined, I'm having to use a math co-processor in order to do the floating point math. I'd like to use the PIC18F chips, but my compiler is slacking and hasn't adapted them yet. I guess it may be time to switch over to a better system!

I just received 4 infrared sensor chips from Chris Anderson on here, so looking forward to trying them out soon for stabilization. However, I would really like to make use of a more accurate gyro/accelerometer setup! ;-)

Hi! I would suggest you to use mikroC compiler for PIC18F. Programming in C language is not so difficult. I find it much better and powerfull than BASIC.
