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.
