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.
