The meaning of the results output from web based GNSS processing
For comparing satellite coordinates produced from broadcast ephemeris with those of the IGS Precise ephemeris (.SP3 file)
The coordinates and velocities of
ISTA point on 10.11.2016 are given to be
X = 4208830.2223 m, Y = 2334850.3312 m, Z = 4171267.3146 m and Vx = -0.0173 m/yr, Vy = 0.0150 m/yr, Vz = -
0.0093 m/yr respectively in ITRF2014. Transform these coordinates to ITRF96, 2005.0
to later on use them in detail measurements.
