Real Time MSGPS
Real Time MSGPS
In Real Time MSGPS mode, selectable scenario files define simulated multiple-satellite conditions. The
E8267D generates a signal (C/A code only) simulating multiple satellite transmissions from the information
in the selected scenario file. MSGPS signal generation capabilities include:
•
selectable MSGPS scenario files that include the following information:
— simulated location (city, latitude, longitude, elevation)
— simulated date and time
— scenario duration
— satellite IDs present (in view) in the scenario
•
pause and resume function for the currently playing scenario
•
restart function that sets the currently playing scenario to the beginning
(without turning off the RF output)
•
adjustable number of satellites in view to include in the generated signal
•
selectable internal or external chip clock reference source
•
adjustable chip clock reference (10.23 Mcps
10%)
•
selectable I/Q phase (normal or inverted)
