Before the Ground Station is switched to operation, check all installation items:
− cabling of equipment and earthing connections
− tight cable fitting, no cable bents
− tight fitting of outdoor equipment
− power supply connections
Check at Ground Station equipment:
a) Check that DC supply jumper on the Ground Station RXU board is inserted.
b) To check the value of the supply voltages for the antenna preamplifiers, switch on the Ground Sta-
tion by setting the DC power switch on front panel to I" (local DC supply has to be set to "on" too).
c) Check the supply voltage for the AAU/LNA at the RF cable on the LNA RFout connector and regis-
ter it in the installation report form in section 3.6. The value has to be between 11.2 and 12.2 V.
d) Check the supply voltage for the GPS antenna at the RF cable on the antenna output and register
it in the installation report form in section 3.6. The value has to be between 4.0 and 5.5 V.
e) Finally switch off the Ground Station and fix and seal the cables at the antennas.
A site verification test procedure and a related installation report form is given in section 3.6.
