GLONASS time signal receiver for precise system time synchronisation

Glonass receiver for accurate time synconisation


The 488HS4-GLONASS receiver system has been designed to allow 5200 series network time servers to be automatically time synchronised from the GLONASS satellite time transmissions. This information provides a highly accurate source of time reference regardless of the global location.

The receiver can operate in either GLONASS only synchronisation mode or GLOSNASS with GPS assistance synchronisation mode.

The 488HS4-GLONASS receiver system is housed in a single IP65 rated case containing both the active antenna module and the receiver/decoder interface. The IP65 rated protective housing shields the 488HS4-GLONASS receiver system from wind, rain and snow.

The connection between the 488HS4-GLONASS synchronisation receiver and the 5200 series network time server is by a four core screened twisted pair cable up to 200m long. This cable also provides power to the 488HS4 receiver/decoder module.

What is GLONASS?

The GLONASS system was developed by the Russian government initially for military use and is now available for unlimited commercial access.

GLONASS is a system of satellites in three orbits, each orbital plane equally spaced about the equator and inclined at 64.8 degrees. The satellites transmit highly accurate, real-time, worldwide navigation information at a frequency of 1598-1609 MHz that anyone with a suitable GLONASS receiver can use to identify their position, together with a precise local time.
