There has been a lot of GNSS-related news in the past month, so I thought I’d do a quick review of the top stories, including L2C and L5 CNAV messages, launch of a new GPS IIF satellite, and Russian threats to disrupt GPS.
It Doesn’t Have to Be ExpensiveGNSS signal simulators can be expensive and beyond the limited budgets of many researchers. In this month’s column, we look at one company’s approach to providing GNSS signal simulation at a low cost — one that virtually any researcher can afford.GNSS signal simulators can be expensive and beyond the limited budgets of many researchers.

Adding GLONASS to GPS gives a total of about 50 satellites, for a significant improvement in navigation availability, reliability, robustness, and convergence time through a new multi-GNSS precise point positioning (PPP) service. System performance and field results demonstrate that there is no need to await future constellations — better performance is available now.
PRN 17 is the first in the new generation of GPS satellites with a new feature called flex power.
When the new flex power feature aboard PRN 17, the first IIR-M GPSsatellite, was enabled for testing (for a very short period oftime), a problem was observed by certain GPS users.
