OpticalNavigationMeasurement:

Path: SpacecraftEstimation/OpticalNavigation

% Computes three types of optical measurements.
 This routine computes up to 5 measurements. You enter information
 in g for up to 2 planets. The data is

   vector from the reference center to planet 1
   radius of planet 1
   star near planet 1
   vector from the reference center to planet 2
   radius of planet 2
   star near planet 2

 The first two are required. The remainder are optional
 You will get the following angular measurements

   chord of planet 1
   angle between star and planet 1
   chord of planet 2
   angle between star and planet 2
   angle between planet 1 and planet 2

 Type OpticalNavigationMeasurement for a demo. The demo rotates the
 spacecraft around the center but everything else is fixed.
