mask_angle:
Description: The mask angle (given by settings gps:mask_angle) determines which GPS
satellites will be used by the system. Any satellite below the specified angle with the
horizon will be masked and not used by the system.
This feature is sometimes useful in optimizing system performance in scenarios where there
may be unusually high amounts of multi-path associated with the GPS signal. Using only
satellites that are higher in the sky can reduce the amount of multi-path and improve
performance but also limits the number of satellites that are tracked. Mask angles that are
too high may cause the system to report a loss of GPS tracking for periods of time.

nasa36:
Description: Select NASA36 output type. The 4387A output modules enable the user to
independently configure an output port to generate a variety of signal formats and
timecodes. The 4387A produces modulated IRIG signal outputs. By default, the output
modules will produce the following signals until reconfigured by the user:
4387A Default Settings:
Port 1: IRIG B120
Port 2: IRIG B120
Port 3: IRIG B120
Port 4: IRIG B120
In order to configure a specific output port the port address must be given. To identify the
port address use the slot number and port number of the desired port.
