Creates a new instance.

Parameters:

angularVelocity - mean angular velocity of the Earth for the GNSS model

weeksInCycle - number of weeks in the GNSS cycle

timeScales - known time scales

type - type (null if not a navigation message)

prn - PRN number of the satellite

toe - time of ephemeris (must be consistent with orbit)

orbit - Keplerian orbit in Earth-frozen frame

nonKeplerian - 15 non-Keplerian parameters (in the order given by NonKeplerianDriversFactory

tgd - group delay differential TGD for L1-L2 correction

toc - time of clock

health - health status

Since:

14.0
