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. Disclaimer: This information is provided exclusively for use by owner-operators of satellites to coordinate space situational awareness related activities. This information should not be used or relied on for any other purpose. Furthermore, information provided is intended to be accurate only as of the date of publication and Planet undertakes no obligation to update this information to reflect current or future events or circumstances. For accurate information with respect to space situational coordination, please email orbital-neighbors at planet dot com if required. 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 5-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) === Conjunctions FAQ === If you are a satellite owner/operator and have a conjunction with one of our satellites please refer to our Conjunctions FAQ.
