QuestionHow do I produce azimuth and elevation values for a line of sight in a satellite's body frame?
Answer
Suppose that you have a scenario set up with access from a satellite to a facility. To get azimuth and elevation angle data in the satellite's body axes, you need to create the following angles in Analysis Workbench.

1. Right-click the satellite and choose Analysis Workbench (User-added image).
2. Click the "Create new Vector" icon and set the following options. This creates a vector pointing from the satellite to the facility.

Create a Dihedral Angle

  1. Click the "Create new Angle" icon.
  2. Set the following options. This will create the azimuth angle based off the satellite's body X axis and read positive towards the Y axis about the Z axis.

Create an Elevation Angle

Lastly, you can set the elevation angle. This will define the elevation angle referenced to the body X-Y plane as positive along the -Z axis.
  1. Click the "Create new Angle" icon.
  2. Set the following options:

Create a new report style

  1. Open up the Report and Graph Manager (User-added image).
  2. Select your satellite as the object type.
  3. Create a new report style and expand the Angles folder. You'll see the azimuth and elevation angles you just made.
  4. Select the Time for one and the Angle for both.
  5. Move these data providers to Report Contents column.
  6. Click OK.

Generate the report

  1. Bring the Report & Graph Manager to the front.
  2. Select the custom report you created.
  3. Generate the custom report.

You'll see the time and Azimuth-Elevation values in your satellite's body frame. You are not limited to computing the angles to a facility. This method will work with other objects.
