GPS180: GPS Satellite Receiver with LC-Display and Control Elements (Eurocard)


The variety of inputs/outputs makes this GPS receiver the first choice for a broad range of applications, including time and frequency synchronization tasks and the measurement of asynchronous time events.

Key Features

Years of warranty: 2 RoHS compliant




Product Description

The frequency locking of the master oscillator to the GPS system enables the module GPS180 to generate fixed and programmable standard frequencies with very high accuracy and stability. Various oscillator options allow to meet different requirements concerning the accurracy of the outputs in the most cost efficient way.

The pulse generator of GPS180 generates pulses per second and per minute. Four programmable outputs are available. The pulses are synchronized to UTC second.

Up to four serial interfaces are available for sending time strings. These ASCII telegrams include information regarding time, date and status of the GPS receiver.

The module provides two inputs for measurement of asynchronous time events. These capture events are shown on the LC-Display and can be read via a serial interface.

The front panel integrates a LC-Display that shows information regarding the GPS receiver in different menus. In combination with four push buttons it is also used to setup all configurable parameters.

Switch outputs Optional:
Four TTL outputs can configured independently for the following modes:
- free programmable cyclic or fixed impulses
- timecode
- timer mode; three 'ON'- and three 'OFF'-states can be setup per day
The switch states can be inverted for all three outputs, the impulse lengths are configurable in 10msec steps in a range from 10msec to 10sec.
The impulse output can be configured for all channels together to 'always' or 'ifsync'.
