GOAL-S is a GPS Optical Antenna Link
Set for connecting a Meinberg GPS antenna/converter (GNSS | IF | 15 V DC) with a Meinberg GPS receiver via a Single-Mode fiber.
- large antenna cable distances - up to 20km. using a continuous connection with a fiber type of category OS2 (0.4dB/km)
- no destructive overvoltage via the antenna cable
- no unintentional monitoring possible via optical fiber
The GOAL-S-R module is connected to the GPS antenna input of the receiver via a coaxial cable at receiver side and can be mounted directly or close to the receiver. The GOAL-S-A module is mounted inside the building and is connected to the Meinberg GPS antenna/converter unit via a coaxial cable.
- long antenna cable runs possible (up to 20km)
- no danger caused by overvoltage damage via the antenna cable
- tap-proof security communication through fiber optic connection
The GOAL-S/R module installed at receiver side is powered by the Meinberg GPS-IF receiver via the coaxial cable. The GOAL-S/A module, installed on the antenna side, requires an external power scource for its own power supply for operation, as well as for powering the connected antenna. An unconnected antenna and a short circuit on the antenna line are indicated by a status LED.
An additional LED indicates that the 10MHz reference is being received by the GPS-IF receiver with sufficient signal strength and that the fiber optic link is working properly. Only when these two status LEDs are green the built-in FP laser is switched on. The switching-on of the laser is indicated by another status LED.
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!).
When using the GOAL-S Antenna link in combination with the GPS signal converter GPSGEN1575, please note, that the function of connected GPS (L1) receivers from other manufacturers can not be guaranteed!
