Detailed Description
This class computes the orbit of the main spacecraft.
Performs orbit determination. It can handle the following measurements:
- GPS: Range and range rates. Effectively this is processed GPS data
- Range: Assumed paired with range rate
- Range rate: Assumed paired with range
- Camera: Preprocessed into angles or as points in the pixel plane
- State: The vehicle state
- ISL: Intersatellite links.
ISL, range, range rate and GPS are all handled the same.
It employs an Unscented Kalman Filter (UKF). Orbit propagation is using the SPICE model with optional spherical harmonics of the central body. Known accelerations can be input.
