The observables document clearly states the pseudo range is set to the earliest TOW, and is 68.802ms. This does not appear to work, and I cannot find anything in the...

Just to confirm, using gnss-sdr-monitor the pseudoranges are random and even negative before a fix is obtained, Then it becomes correct at the real satellite range ~ 22-25,000km. Clock offset...

Same here, Asked the provider of the static library for STEREO receiver for either the source code or an update. Waiting for it. Also libfec.a seems to be related tothe...

We have a system which generates a simulated satellite signal. Even when switched off we can see tracking messages. I assumed this was seeing a real satellite giving a strong...

Well, I can confirm that a RTL-SDR V3 dongle connected to a good external antenna (Tallysman triband) works perfectly well. Replacing the antenna with a 50R and a DC block...

Our gnss-sdr based system appears to detect non existent signals! Locking on noise I can understand but we also see GPS NAV messages with a constant pseudorange from channels that...

Not sure I agree 100% with this. If there is NO signal then we never get a tracking message. However, I can now confirm that because PRN cross correlation rejection...
