GNS181: GPS / GLONASS / Galileo / BeiDou based Time Synchronization for Stationary and Mobile Applications

The GNS181 unit has a special onboard receiver which is able to capture GPS, GLONASS, Galileo and BeiDou signals. Optionally, it is possible to limit the receiver to using only one satellite system or a combination of two or three GNSS systems for synchronization.

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

The GNS181 with its integrated GPS / GLONASS / Galileo / BeiDou receiver provides accurate time with ultimate precision both in stationary and mobile environments by supporting standard L1 antennas.



Product Description

The GNS181 offers satellite based time synchronization at the highest accuracy standards for fixed or mobile applications. It is suitable to be deployed in data centers or on board of cars, trucks, aircrafts, ships and other moving platforms. The satellite receiver can determine its position even at a maximum acceleration of up to 5 g, at a maximum speed of 500m/s and at an altitude of up to 18,000 meters.

The GNS181 is used to manage high accurate timing and measurement tasks. The board is able 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 the GNS181 generates pulses per second and per minute. As an option four programmable outputs are available. The pulses are synchronized to the UTC second.

The module provides two inputs for measurement of asynchronous time events. These capture events can be read via a serial interface. The board uses a binary interface protocol to receive configuation parameters and exchange status information with external equipment via its RS232 interfaces.

MRS capability
The oscillator of the GNS181 can be disciplined by an external reference source (e.g. 1PPS, 10MHz, IRIG, PPS + String).

Standard L1 Antenna
Standard delivery includes a 40 dB Multi_GNSS L1 antenna. The antenna with an integrated over-voltage protection operates in a frequency range of 1575.42 +-10 MHz and 1602-1615 MHz.
