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.

=== 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.

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)
