Moin, This just came in trough my feeds. Maybe someone finds it interesting: https://github.com/osqzss/gps-sdr-sim Attila Kinali -- I must not become metastable. Metastability is the mind-killer. Metastability is the little-death that brings total obliteration. I will f

Hi Warren: Here's some info on a GPS signal generator made by Stanford Telecom for testing their GPS ICs: http://www.prc68.com/I/5001A.html I'm sure it could be greatly reduced in size and complexity be replacing all the logic with a micro controller, but the RF part would remain. There is a ve

In my quest to keep improving my GPSDO, a simple test tool that I find indispensable is a GPS 1PPS (or 100Hz) signal simulator reference. Others may also find this useful because it allows testing the PLL & DO in their GPSDO to Cs type accuracy using a standard OCXO. The advantages of
