Real Time MSGPS
Signal Generation Block Diagram
Figure 8-1 shows how the signal is generated within the PSG for a four satellite MSGPS simulation. The
PSG produces a simulated signal for each satellite and then sums them together to produce the MSGPS
signal. Use the
Number of Satellites softkey to specify the number of satellites in the MSGPS simulation.
