GPS and Galileo Satellite Receiver with Up-Converter for Meinberg GPS Antenna/Converter
GPS/Galileo based Time Synchronisation for Stationary and Mobile Applications using Meinberg Antenna/Converter Technology
The GNS181-UC unit has a special receiver concept which is able to capture GPS and Galileo signals using a standard Meinberg antenna/converter unit. The configuration supports to select one of these to be used exclusively or the combination of the sources.
The receiver is capable of operating during high speed movement and delivers reliable and highly precise Synchronisation solutions in stationary installations and on fast moving vehicles, such as aircraft, ships or trucks.
The variety of inputs/outputs makes this receiver the first choice for a broad range of applications, including time and frequency Synchronisation tasks and the measurement of asynchronous time events.

| Further information |
The GNS181-UC with its integrated GNSS receiver provides accurate time with ultimate precision both in stationary and mobile environments by supporting long antenna cables because of the Meinberg antenna/converter technology.
The GNS181-UC offers satellite based time Synchronisation at the highest accuracy standards for fixed or mobile applications. It is suitable to be deployed in data centres 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 4 g, at a maximum speed of 500 m/s and at an altitude of up to 18,000 meters. The GNS181-UC 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 accuracy of the outputs in the most cost efficient way. The pulse generator of the GNS181-UC generates pulses per second and per minute. As an option four programmable outputs are available. The pulses are Synchronised 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 configuration parameters and exchange status information with external equipment via its RS232 interfaces. MRS Capability The oscillator of the GNS181-UC can be disciplined by an external reference source (e.g. 1PPS, 10MHz, IRIG, PPS + String). Standard delivery includes a Meinberg antenna/converter unit. |
