| Summary: | Conventional georeferencing using ground control points (GCPs) provides reliable
positioning but the geometrical accuracy critically depends on the number and spatial
layout of the GCP. The limitations may overcome by direct georeferensing such as
post processing kinematic (PPK) and real time kinematic (RTK) using GNSS (Global
navigation satellite system) observation data. The aims of the study is assessment
contribution of the positioning quality from the various combination GNSS is used
for PPK method. The data used are GNSS observation from GNSS on board in the
UAV. The assessment of the contribution of the various combinations GNSS by
comparing the result of solving ambiguity phase and the solution of techniques for
solving ambiguity phase. In additional to that the coordinat will be comparing among
the PPK and RTK result.
The technique of integer ambiguity resolution fix and hold or continuos and
combining GPS with Beidou provides the solving of phase ambiguity and precision
better than the other GNSS combinantions. In additional to that, the difference
coordinat between PPK and RTK methods in the cm level. However, PPK method
provides a better precision compared RTK method. |
