Relative orbit estimator implementation as part of the gnc library.
PSim relative orbit estimator model.
PSim RelativeOrbitEstimatorTest simulation.
Testing
Originally with a process noise value of S = 1.0e-4 I gave the following results:
which perform fairly well and although when the CDGPS goes out of range you can see the covariance bounds of the position estimate are very conservative - likely because the process noise for the position states is too large. Secondly, the covariance bounds on the seem too tight on the z velocity component. Taking this into account, the process noise values were updated.
Rebasing once #302 and #304 are merged.
Fixes #298.
