Geodetic observatory PecnÃ½


If reliable navigation messages are available for any global constellation, Anubis estimates coordinates of the receiver using the standard point positioning (SPP) method and pseudorange observations only. The receiver position is currently estimated for each GNSS separately using a common sampling rate of 15 minutes. Below figures show a) left: the comparison of RMS of NEU coordinate repeatability (expressed in meters) from individual available GNSS and b) right: horizontal epochwise positioning with a relative size of point calculated from the Geometric Dilution of Precision (GDOP) values.
Setting sec_est="1" requests the output of mean coordinates and rootmeansquares calculated from coordinate repeatabilities. Individually, Cartesian and spherical coordinates are reported, while for the latter rootmeansquares are expressed in North,East,Up [m]. Finally, numbers of epochs of all observations and epoch of outliers are reported.
Setting sec_est="2" enables epochwise estimates reported in Cartesian and spherical coordinates and the GDOP.
