How do I configure the elevation mask angle on the CLAW GPS Simulator™?
Purpose of the Elevation Mask Angle:
The elevation mask angle determines which satellites are enabled and visible in the simulated RF output. Only satellites above the specified angle will be active.
Matching the Receiver's Elevation Mask Angle:
To ensure all satellites used by the target receiver are enabled, the elevation mask angle on the CLAW GPS Simulator™ should be set to equal or less than the elevation mask angle configured on the target receiver. Refer to the target receiver's documentation for its elevation mask angle settings.
Setting the Elevation Mask Angle:
Use the SIM:SV:MASK command to configure the elevation mask angle. For example:
To set a mask angle of 10 degrees:
SIM:SV:MASK 10
Supported Range and Constraints:
The mask angle can be set between -90 to +90 degrees, allowing simulation of satellites below the horizon. However, most receivers do not support mask angles below the horizon.
The CLAW GPS Simulator™ can simulate up to 18 satellites at a time. In typical orbital configurations with 30 satellites, the number visible above the horizon rarely exceeds 10.
