keplime // Physics
A high-performance orbital mechanics package
keplime is Citra’s astrodynamics library. Every product propagates, transforms and fits orbits through it, so a prediction in the field matches the one in the catalog.
01 // Capabilities
What It Does
Propagation
SGP4 and numerical integrators behind one interface, with force models in one place.
Frames and Time
Coordinate frames, time scales and ephemeris, converted the same way everywhere.
Orbit Determination
Batch fits and EKF and UKF filters with covariance, association and conjunction.
