Some crystal oscillators specify their sensitivity to G forces. Here is one: http://www.abracon.com/Precisiontiming/AOCJYR-24.576MHz-M6069LF.pdf

But all of the ground stations will see the same frequency shift on the rocket's transmitter. I think this can be backed out in processing. Someone needs to write the equations and post them here. -- Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
