Damage to GPS from RF Transmitter

[FPVProject 0]

Hi,

I've read about GPS being damaged from being to close to an RF transmitter. Doesnyone know how close is too close or if there is a reccomended way of sheilding ?

Thanks

Sounds like a PM to Thomas Scherrer of Intelligent Flight is the key to answer. This happened to him last year.

I thought his was damaged when he keyed up his nearby ham radio transceiver. In any case, for model aircraft installations, I recommend watching the GPS satellite count and then find a mounting location where the number does not decrease when the A/V Tx is turned on. With a 500mW Tx, the closest I have ever been able to do that was about 12 inches. Much further is best.

Thanks for your response guys. That is a lot further than I expected. It's actually in relation to an Xbee module and not a video Tx. I was hoping to mount them both on the same board/pcb but we'd be talking only a couple of cm's not 12 inches ! Still have to wait for Sparkfun to get the modules for actual testing, was chasing a ballpark figure.

Thanks again guys.
