GPS timing reference Megger MGTR-II

GPS timing reference Megger MGTR-II

The MGTR-II is a small, lightweight, field portable, GPS satellite receiver system specifically designed to perform end-to-end tests of line protection schemes, with Megger SMRT, MPRT, and PULSAR relay test systems. The MGTR-II provides a precise programmed output pulse (POP), with 100 nanoseconds of resolution. This output pulse provides a trigger synchronization of two or more SMRT, MPRT, or Pulsar test systems to less than ±1 µ Sec of the Universal Time Coordinated (UTC).

The MGTR-II consists of a twelve-channel GPS timing receiver integrated with proprietary microprocessor-controlled timing and interface logic. The MGTR-II simultaneously tracks all available GPS satellites. The microprocessor-controlled timing and interface logic derive precise timing information. In addition, the MGTR-II provides a standard 1 Pulse Per Second (PPS), an ASCII serial time message, an external event time tag, an IRIG-B serial time code output signal, and most importantly, a programmable output pulse for performing end-to-end tests.
