The challenge

Carrier phase differential GPS (CDGPS) is a widely used system for relative positioning. However, the carrier phases are periodic and require an ambiguity resolution which can be performed today only with a failure rate of a few percent due to the small carrier wavelength. This is far too much for safety of life critical applications.


The solution

ANAVS is developing differential Galileo/GPS receiver systems with a new integer ambiguity resolution technique that uses soft baseline constraints and multi-frequency code carrier combinations.

It enables a failure rate of less than 1e-7, and can be used for a wide range of applications including freight stabilization of cranes and helicopters, navigation of trains and ships, for attitude determination systems, and bridge constructions.
