Checking the installation site of the GNSS antenna
Preparation:
n The installation and connection of the GNSS antenna must have been completed.
1. Check the installation site of the GNSS antenna for proper condition, such as the
n fastening of the antenna mast,
n fastening of the GNSS antenna,
n cable routing.
Circumferential range of vision (angle of unobstructed visibility of the sky) of the
GNSS antenna.
A good circumferential range of vision (angle of unobstructed visibility of the sky
according to the recommendations of the manufacturer) must be maintained to ensure
proper reception of the GNSS antenna. The angle of the GNSS antenna supplied is 90°.
When using a third-party GNSS antenna, heed the corresponding documentation sup-
plied with the GPS antenna.
2. Check the circumferential range of vision of the GNSS antenna.
➔ The visual inspection has thus been completed.
4.3.6.2 GNSS operational monitoring (via NMC-511 FaultManager)
The function of the GNSS receiver and the detectable GNSS satellites are monitored by
the DIB-R5 advanced based on the GNSS data received.
Using the NMC‑511 FaultManager network management client, faults occurring in an
ACCESSNET-T IP network can be detected and localized rapidly. This facilitates prompt
fault elimination.
All network constituents and connections of an ACCESSNET-T IP are monitored via the
NMC-511 FaultManager. Operating states and faults are detected by the network man-
agement system and visualized via the connected workstations, on which the NMC-511
FaultManager is installed and enabled.
The NMC-511 FaultManager displays the operating states and faults of the network con-
stituents in the respective network in an alarm status list. This makes permanent network
monitoring possible.
The procedures for this purpose are described in corresponding documents, refer to the
following table.
