Fiber-optic GPS antenna splitter for secure signal transmission over long distances

ADU is an antenna distribution unit for connecting a Meinberg GPS antenna/converter (GNSS|IF|15V DC) to several Meinberg GPS receivers (up to eight receivers) via single mode fiber lines.

Description

Product Description

The ADU system must be mounted inside the building and connected to the Meinberg GPS converter antenna via a coaxial cable.

The GOAL-S-R module is connected on receiver side to the GPS antenna input of the receiver via a coaxial cable and can be mounted close to the connected receiver.

The two modules (ADU and GOAL-S-R) are interconnected via E9/125µm single-mode fiber. This type of antenna connection has the following advantages:

    • long antenna cable runs possible (up to 10km)
    • no danger caused by overvoltage damage via the antenna cable
    • tap-proof security communication through fiber optic connection

The GOAL-S/R modules installed on receiver side are powered by the Meinberg GPS-IF receiver via coaxial cable. The ADU/FOS/MP system installed on antenna side requires an externally supplied voltage for its own power supply as well as for feeding the connected antenna through the built-in GPS receiver.

The system is suitable for the subsequent extension of existing Meinberg GPS systems. The following GPS receivers are suitable for use with a GOAL-S Antenna Link:

and older receivers of the series GPS163, GPS164, GPS165, GPS167, GPS168, GPS169 and GPS170 (but not GPS166!).
