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: http://arxiv.org/abs/1509.03270


=== JSpOC matching ===
Provides best-guess matching between JSpOC CATID and Planet Labs HWID.
Not always consistant due to JSpOC cross-tagging.

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 10-day ephemeris prediction:

where HWID is the satellite ID (see JSpOC matching for HWID-CATID conversions)
