Signal Generation Block Diagram
Figure 11-1 shows how the signal is generated within the ESG for a four satellite MSGPS simulation. The
ESG 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.
