satellite positions and clocks.

satellite position and clock are values at signal transmission time. satellite clock does not include code bias correction (tgd or bgd). any pseudorange and broadcast ephemeris are always needed to get signal transmission time.

Parameters

trace	Trace to output to
teph	time to select ephemeris (gpst)
obs	observations to complete with satellite positions
nav	Navigation data
posSources	Source of ephemeris data
clkSources	Source of ephemeris data
kfState_ptr	Optional pointer to a kalman filter to take values from
remote_ptr	Optional pointer to a kalman filter to take values from
offsetType	Point of satellite to output position of
applyRelativity	Option to apply relativistic correction to clock
