Do any of you know any details of an unknown GPS DO. Visual GPS
identifies it as
a Motorola VP/GT. It fas a Motorola 5 MHz. packaged oscillator and a
Motorola GPS receiver.
The receiver is apparently a 6 channel model. One of the circuit boards
are marked 1991-1994.
It has 1 Hz, pulse and 5 MHz. on the back and front . but the back is
only activated when it
is "in service" It also has a RS232 interface on the back and two
connectors I don't understand. One is a two row 10 pin header the other
connector is a "RJ" (similar to telephone) connector.
It apparently works, but even when the "in service" light is on it it
is still not locked when I compare
it to anther GPSDO
Any source of information on this unit is appreciated
