Direct GPS Propogation

Given direct GPS measurements from the FINCH satellite, the Direct GPS Propagator extrapolates the satellite's trajectory to estimate when the FINCH mission will be within its imaging range.

Plots

The Direct GPS Propogator plots the following:

• The satellite's ground track
• The imaging target
• The imaging range around the target
• The predicted trajectory of the satellite and when the trajectory is within the targeted imaging range
• The error of the predicted trajectory
