Unitary tests for the numerical propagator
We have validated the numerical propagator, using several integrators
(DOP853, RK4, GBS), different force models (potential up to 60x60 order,
3rd bodies, SRP, atmospheric drag), on different orbits (LEO, MEO, GEO,
HEO). Reference data come from our numerical propagators used for high
accurate orbit determination.
We propose to extract some use cases to improve OREKIT unitary tests.
These tests would cover some of the more significant use cases : 5 days
propagation on a LEO orbit with all conservative forces, 10 days
propagation on a GEO orbit with all conservative forces and SRP, etc.
Each test will compare a numerical propagation with the results we
obtained during our validation tests. The initial deviation with our
reference tools will also be documented.
