The biggest problem I see is the crystal oscillator in the rocket is going to notice the G forces during acceleration in a pretty big way. Time nuts easily notice the reversal in a 1G force on a laboratory oscillator caused by flipping it on its back for service.
But all is not even close to lost. If your transmitter is amplitude modulated with a rate that is a digital division of your crystal's frequency, then you can remove any G-variation in the crystal's frequency by observing frequency variations in your modulation. Doppler will change the carrier frequency with speed, but it won't change the amplitude modulation frequency. Otherwise it should work beautifully. -Chuck Harris Peter Reilley wrote:
Robert; It seems that a Doppler system should work for you. But first, you have a problem. If you want to track your rocket to 100K feet (20 miles) using some form of triangulation then you need your receiving stations further apart than 1 mile. Your triangle is too extreme and any measurement error will be greatly amplified. Here is what I suggest.
