DAR-eL100-S
eLoran Signal Generation & Control System
The system provides 100kHz envelope eLoran signal generation function for advanced terrestrial navigation, LDC (9th Pulse/Eurofix) modulation/demodulation function for processing correction information, time correction function for system timing synchronization, and high-power transmitter interface function.
This system has the function of ensuring service continuity by monitoring and controlling the signals transmitted from the redundant system.
