GPS170 Features
The front panel integrates a 2 x 40 character LC display, two LED indicators and five
push buttons. The receiver is connected to the antenna/converter unit by a 50 ohm
coaxial cable (refer to "Mounting the Antenna"). Feeding the antenna/converter oc-
curs DC insulated via the antenna cable. Optional an antenna splitter for up to four
receivers connected to one antenna is available.
GPS170 is using the "Standard Positioning Service" SPS. The navigation message
coming in from the satellites is decoded by GPS170´s microprocessor in order to track
the GPS system time. Compensation of the RF signal´s propagation delay is done by
automatical determination of the receiver´s position on the globe. A correction value
computed from the satellites´ navigation messages increases the accuracy of the
board´s oven controlled master oscillator (OCXO)
and automatically compensates the
OCXO´s aging. The last recent value is restored from the battery buffered memory at
power-up.
The GPS170 provides different optional outputs, i.e. three progammable pulse
outputs, modulated/unmodulated Time code output, and up to a total of four RS232
COM ports. Additionally, you can order the GPS170 with different OCXOs (e.g.
OCXO-LQ / MQ / HQ /DHQ or an external Rubidium) to match the required
accuracy.
The hard- and software configuration of the clock is dis-
played if the NEXT key is pressed two times from the root
menu.
