Navigation Solutions - ANAVS has a wide experience of reliable carrier
phase positioning with single and multi-frequency GNSS measurements,
and develops software and hardware for heading and attitude determination, for
Real-Time Kinematics (RTK) Positioning, and for Precise Point
Positioning (PPP) in both static and dynamic environments.
ANAVS's patented differential positioning technique includes the first method, which resolves the carrier phase integer ambiguities with an extremely low error rate. We achieve highest success rates by the inclusion of statistical baseline a priori information into the ambiguity fixing, by the use of a new group of multi-frequency code carrier linear combinations, and by the use of an adaptive state space model for the heading and pitch angles. Our multi-frequency linear combinations allow an arbitrary scaling of the geometry, an arbitrary scaling of the ionospheric delay, and any preferred wavelength. The maximization of the ambiguity discrimination increases the wavelength from 19.0 cm to more than 3 m, and suppresses the code multipath on L1 by more than 10 dB, which enables an extremely reliable resolution of the carrier phase integer ambiguities. Moreover, ANAVS has developed a reliable carrier phase based heading and attitude determination system without the need of integer ambiguity resolution for single frequency, low cost applications. It performs a kinematic on-board calibration of the carrier phases and a subsequent coasting.
