Description

LISA Orbits is a Python package which generates orbit files compatible with LISA Instrument, LISA GW Response, the LDC Software, and LISANode. Among others, an orbit file contains the spacecraft state vectors, the light travel times and the proper pseudoranges.

User manual and documentation are available here.
