Bernese GPS Software Version 5.0 - Bernese GNSS Software

7.8 Program Output and Extraction Program
• list of all input and output filenames, including path specification,
• list of observation files, station names, receiver names, number of observations, and
list of observed satellites for each input file,
• selected cutoff angle, sampling rate, a priori RMS of unit weight, observation weighting
scheme, ambiguity resolution strategy, etc,
• a priori station coordinates, geodetic datum, selected specifications for datum definition,
• satellite orbital elements, satellite problems in the processed session according to satellite
problem file,
• a priori troposphere model selected, mapping functions, troposphere parameter setup
for each station, including imposed constraints,
• informations on ionosphere model used, and
• pole information used.
The results section is divided into two parts (PART 1 and PART 2) if ambiguities are resolved
to integers. The first part gives the results before, the second part after ambiguity
resolution. If no ambiguities are resolved only the first part is printed. The results section
gives statistical information on the solution as well as detailed information on the estimated
parameters, in particular improvement and formal errors, also for parameters which are not
written to an output file. Particular attention is payed to a comprehensive presentation of
the results concerning the estimation of station coordinate and baseline vector estimation.
In a standard GPSEST network processing run you find the following information:
• A detailed statistics is provided for each type of estimated parameters the number of
parameters which are set up, which are pre-eliminated, or which are singular.
• The numbers of used observations from each observation file are listed.
• The a posteriori sigma of unit weight, converted to the one-way L1 phase observable
(at zenith in case of elevation-dependent weighting), together with degree of freedom
f and χ 2 /f of the solution are printed.
• A priori and estimated coordinates for each station, in geocentric as well as in elliptical
coordinates, coordinate improvements, RMS errors, and error ellipsoids are tabled (see
Section 10.3.1 for more details).
• If ambiguities are resolved detailed information is provided for each ambiguity before
and after resolution to integer as well as on each iteration.
• Information on troposphere zenith delay parameters as well as on gradient parameters
are provided (corrections and formal errors). For gradients zenith tilting angles and
error ellipsoids are given.
• A table RMS ERRORS OF ELLIPS. COORDINATES AND COORDINATE DIFFER. lists in
the form of a matrix for each station combination the formal RMS errors of the
baseline vector in the three components in the local frame (B: latitude, L: longitude,
H: height component). The diagonal elements give the formal errors of the coordinates
of the respective station.
• A triangular table SLOPE DISTANCES AND RMS ERRORS specifies for each baseline the
vector length (O: a priori, N: a posteriori) and its formal RMS error.
