Input files Rover observation (RINEX OBS) PPP corrections Base observation (RINEX OBS) Navigation (RINEX NAV) optional Precise orbit (SP3) optional Precise clock (CLK) optional

MADOCA L6E logs orbit / clock / bias: every channel and hour of the run

MADOCA L6D logs optional: ionosphere over Japan and Australia

CLAS L6 log HAS corrections (IDD, RTCM 3 SSR) HAS E6-B page log cssrlib text, u-blox RXM-SFRBX or Septentrio SBF Antenna model (ANTEX) optional

Galileo HAS gives float PPP (no phase biases, so no ambiguity resolution) with GPS and Galileo; use the broadcast NAV of the same day, with Galileo I/NAV. East Asia and the Pacific (90°E–180°E) are outside its service area.

QZSS L6 logs are the 250-byte frames of an L6 receiver or the hourly files of the QZSS archive; use the broadcast NAV of the same day.
