--- The maintenance page. The configuration parameters described below are set at this page.This page describes the device driver and the device window for the Show-Orbit logical device. This device calculates a satellite's orbit position from the azimuth angle of the antenna.
The Show-Orbit logical device may be used to display the orbit position an antenna is actually pointing to. Please note, that the device does not look at the antenna's elevation angle, the orbit position is calculated straight from the azimuth value.
There are two read-only variables representing the calculated orbit position: orbit contains the value as a floating point number expressed in degrees eastern longitude. This variable conforms to the standard notation of satellite positions in the sat-nms software. It may be used for both, displaying the value and feeding it into other calculations. The variable orbitText displays the value as a string with two digits precision and a "°E" or "°W" unit appended, depending on the satellites position.

At the maintenance page of the device window there are a couple of configuration parameters which must be set to integrate the device into the VLC/M&C.
| parameter | description |
|---|---|
| azimuthId | The parameter ID of the azimuth angle to monitor. |
| longitude | The longitude of the antenna's geodetic location. |
| latitude | The latitude of the antenna's geodetic location. |
