Chapter 5 - I/O Commands
SATELLITE MASK ANGLE COMMAND (@@Ag)
Applicability: M12+ Positioning and Timing receivers
The receiver will attempt to track satellites for which the elevation angle is
greater than the satellite mask angle. This parameter allows the user to control the elevation
angle that was used for this decision. Typical values are between 5 and 10 degrees. Depending
on the antenna used, the receiver is capable of tracking satellites down to the horizon, but range
and therefore time errors will increase due to atmospheric distortion of the signals from the low
satellites.
Range: 0 to 89 degrees
Default values:
M12+ Positioning Receiver: 0 degrees
M12+ Timing Receiver: 10 degrees
Legacy Compatibility: The @@Ag command has been implemented in an identical fashion in
virtually all Motorola Oncore receivers.
