Beacon Receiver
Parameter
Name
Description
Beacon RX
type
Selects the source of the beacon level the ACU shall use. Available options
are SATNMS and VOLTAGE. In SATNMS mode the ACU reads the beacon
level from a sat-nms beacon receiver via UDP, in VOLTAGE mode the A/D
converter input of the ACU is read. Please mention, that in SATNMS mode,
the beacon receiver must be set to send UDP datagrams to the ACU/ODM.
Beacon RX
IP address
The IP address of the beacon receiver. Applicable only in SATNMS mode.
Beacon RX
voltage
scale
The scale factor for the analog beacon level input. The value must match the
scaling of the beacon level signal.
Beacon RX
0V level
The beacon level which is displayed if the ACU recognizes 0V beacon level
input.
Location
Parameter Name --- Description
GPS receiver type --- Defines the type of GPS receiver the ACU uses to read its geodetic
location.'NONE' tells the ACU that no GPS receiver is connected. The geodetic position of
the Antenna has to be entered manually. The ACU synchronized its internal clock to the
CMOS clock chip on the board.'NMEA' tells the ACU to expect messages from a NMEA GPS
receiver connected to the serial interface at CON8, pins 1-3. The ACU automatically sets the
antenna's geodetic location to the values received and synchronizes the clock to the GPS
timestamps. If no NMEA messages are received, the ACU states a fault.
Antenna course --- The Antenna course is an additional offset which is included into the
azimuth calibration. It is used for mobile antennas to set the orientation of the antenna
without recalibrating it. For stationary antennas this value always should be set to 180°.
Antenna longitude --- The geodetic longitude of the antenna. For a precise orbit to pointing
calculation this value should be entered with 0.001° accuracy.
Antenna latitude --- The geodetic latitude of the antenna. For a precise orbit to pointing
calculation this value should be entered with 0.001° accuracy.
Antenna abs. altitude --- The absolute altitude over sea of the antenna location.
