PLANET LABS PUBLIC ORBITAL EPHEMERIDES Planet Labs performs orbit determination on its own satellites from GPS and 2-way UHF ranging and provides this data publicly in various formats. Technical reference: https://arxiv.org/abs/1509.03270 === 18 SPCS matching === Provides best-guess matching between 18 SPCS CATID and Planet Labs HWID. Not always consistant due to 18 SPCS cross-tagging. https://ephemerides.planet-labs.com/18SPCS_matches.txt NEW! We are trying out a new matching table that is intended to reduce ambiguity of satellite matches before they have been catalogued officially by the 18th SPCS. Feedback is welcome. https://ephemerides.planet-labs.com/18SPCS_matches_v1.txt === Operational Status === Provides operational status of Planet Labs satellites. https://ephemerides.planet-labs.com/operational_status.txt NEW! We have extended the new concepts in the 18SPCS_matches_v1.txt file to a new format of the Operational Status table. As above, feedback is welcome. https://ephemerides.planet-labs.com/operational_status_v1.txt === TLEs === Latest: https://ephemerides.planet-labs.com/planet_mc.tle Historical: https://ephemerides.planet-labs.com/planet_mc_YYYYMMDD.tle === State Vectors === Latest: https://ephemerides.planet-labs.com/planet.states Historical: https://ephemerides.planet-labs.com/planet_YYYYMMDD.states State vector file format: Col1: Satellite Hardware ID (HWID, a 4-digit hex number) Col2: Epoch in [s] since J2000 epoch Terrestrial Time Col3,4,5: Position in J2000 frame [m] Col6,7,8: Velocity in J2000 frame [m/s] Col9: Drag Ballistic coefficient in [kg/m2] Col10: SRP ballistic coefficient in [kg/m2] (not currently fit) === Ephemeris predictions === Per-satellite 8-day ephemeris prediction: https://ephemerides.planet-labs.com/HWID_oem.txt SkySat 95-day ephemeris prediction: https://ephemerides.planet-labs.com/HWID_long_term_oem.txt where HWID is the satellite ID (see 18 SPCS matching for HWID-CATID conversions) === Contact === For technical or operational questions, or to request permission to redistribute these data or use in a publication, email orbital-neighbors at planet dot com
