Satellite Based Positioning
The invention relates to a positioning of an assembly 1 . An assembly 1 comprises a GNSS receiver 3 and a wireless communication module 2 and may exchange GNSS information with other assemblies 1 using cellular or non-cellular links. Relative positions between assemblies 1 are determined based on GNSS measurements at the assemblies 1 . An API 70 supports a communication between a GNSS receiver 3 and a wireless communication module 2 . A positioning is made controllable by a user interface 122 . A positioning server 4, 6 may forward information from one assembly 1 to the other or take care of the position computations for assemblies 1 . An absolute positioning is enabled by means of a GNSS receiver 7 arranged at a known location and coupled to such a server 4 . A network of positioning servers enables an information exchange between positioning servers 4, 5, 6.
