Generating Distorted GNSS Signals Using a Signal SimulatorIn this month’s column, our authors discuss a set of GPS and Galileo evil-waveform experiments they have carried out with an advanced GNSS RF signal simulator. Their results will help to benchmark the effects of distorted signals and perhaps lead to improvements in GNSS signal integrity.

According to a spokesperson from the Space and Missile Systems Center, GPS Directorate, the Russian Space Agency (RSA) has been assigned L1 pseudorandom noise (PRN) C/A codes for its System of Differential Correction and Monitoring (SDCM) transponders on the Luch series of geostationary relay satellites.
Following the recent launch of two Galileo satellites, Thales Aviation of Valence, France, has successfully acquired and tracked the new L1 Open Service signal transmitted by one of them (PRN 11) with a new Galileo high-end receiver made by the company.
Researchers at the German Aerospace Center say they have found a small variance in the L5 signal on IIF-1. The signal variation results in no more than a 5-centimeter error with a predictable periodicity of about six hours. The GPS Wing is studying the issue and expects to resolve it before setting the satellite healthy, in another month or so according to the schedule.
The U.S. Air Force spoke briefly for the first time in public regarding signal anomalies from the IIR(M)-20 satellite launched in March.
