Abstract:

 


In recent years Precise
Point Positioning (PPP) technique is one of the most important subjects in
Geomatic Engineering. PPP technique needs only one Global Navigation Satellite
Systems (GNSS) receiver thus users have preferred it instead of traditional
relative positioning technique for several applications. Nowadays, scientific
software generally has been used for PPP solutions and the Variance covariance
(VCV) matrices estimated from software are very optimistic. The formal errors
estimated from VCV matrices have major effects on statistical interpretation.
VCV matrices derived from GNSS processing software play important role for
deformation analysis and scientists sometimes need to scale VCV matrices. In
this study, 10 continuously operating International GNSS Service (IGS)
reference stations have been considered for 11 days dated 2014. All points have
been analyzed by GIPSY-OASIS II v6.4 scientific software. It is aimed to
estimate scale factor for the PPP results obtained from GIPSY-OASIS II v6.4
with considering different session durations as 2, 4, 6, 8, 12 and 24 hours.
According to the results, the values of the scale factors raise depending on
the raises in respect of session duration.
