GPS-3903
GPS Receiver and Antenna Systems
The NEO® GPS-3903 and standalone GPS receiver/antenna allow the CSD-3902
master clock driver, the VSG-410 signal generator and MTG-3901 master timing
generator to provide outputs with great accuracy by using the most accurate
source of time used in the public domain — a system of 24 satellites that provides
complete coverage in any part of the world with information on time and position.
This makes the CSD-3901/2 and MTG-3901 totally independent from telephone
or radio receiver standards.
