s
Functional
Antenna send this in response to F command and repeat
periodically confirming that antenna is pointed to the satellite
Functional – 0 (no)/1(yes) and if router may activate its
transmission Ok-to-Transmit – 0 (no)/1 (yes).
OK-to-Transmit
W
Location update, sec
Location time. Antenna should send this message immediately,
and then repeat at list this often. 0 means “never repeat”.
w

Time
Antenna sends this to router periodically. The period if set by the
“W” command. Confirms if location is not valid (Valid=0).
Q
(not specified)
C/N
C/N level of the locked carrier (C/N, dB*10).
6.2
COTM with use of SNMP
Alternatively to OpenAMIP protocol UHP router may exchange data with mobile antenna controllers using SNMP
protocol with the appropriate MIB. The following information can be exchanged between the controller and the
router:
Receive level;
Status of the demodulator;
Status of finding a carrier;
Turn on/off the modulator;
Current geographic location (in the NMEA format).
Information about current geographical location of the Station can be exchanged via built-in (optional) serial
interface (console) of the router.

Automatic Beam Switching
UHP router can assist a mobile antenna in pointing to the appropriate satellite according to the current location of
the Station and preconfigured coverage zones with corresponding EIRP. Therefore the mobile Station may select
the most appropriate satellite or its beam for its current geographic position.
