IMS-GNS181-UC - GPS/Galileo based Time Synchronization for Stationary and Mobile Applications using
Meinberg Antenna/Converter Technology
The IMS-GNS181-UC unit has a special receiver concept which is able to capture GPS and Galileo sig-
nals 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
synchronization 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, includ-
ing time and frequency synchronization tasks and the measurement of asynchronous time events.
The IMS-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.

Description
The IMS-GNS181-UC 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 4 g, at a maximum speed of 500 m/s and at an altitude of up to 18,000 meters.
The IMS-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 os-
cillator options allow to meet different requirements concerning the accurracy 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 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-UC can be disciplined by an external reference source (e.g. 1PPS, 10MHz, IRIG,
PPS + String).
