DAR-6000T+
Launching SoonEnhanced eLoran Exciter
The enhanced eLoran Exciter will feature SAE9990 standard-based analysis, delivering improved compliance verification and more precise performance evaluation beyond the capabilities of the previous version.
The eLoran Exciter is a device that generates an eLoran Pulse signal that inserts LDC (Loran Data Channel) information based on the received reference time information and then transmits it to the eLoran transmitter.
The eLoran Exciter performs a TOT automatic control function based on the received TOT status value to control the error between the time of the antenna transmission signal and the reference time to be within the error tolerance range.
The eLoran Exciter performs the function of measuring the signal quality of the output signal.
