Add Real-Time PPP Ambiguity Resolution (AR) Capability

[lntuch18l@…]

It is recommended to add a real-time PPP (Precise Point Positioning) ambiguity resolution (AR) capability to the BNC software in order to improve the convergence speed and positioning stability of high-precision applications. The current version only supports float PPP solutions and lacks support for real-time integer ambiguity fixing, which limits its potential in achieving centimeter-level accuracy.

The proposed feature should include the following:

Integration of ambiguity resolution algorithms supporting dual-frequency or multi-frequency observations (e.g., LAMBDA, TCAR, etc.);

Support for multi-GNSS AR, including BDS, GPS, and Galileo systems;

Automatic detection and fixing of ambiguities that meet solvability criteria;

Output of coordinates based on fixed solutions, along with AR status flags;

Diagnostic information in the user interface or logs, such as AR solution status, success rate, and the number of fixed ambiguities.

This feature would significantly enhance BNC’s usability and reliability as a real-time PPP engine, particularly in high-precision applications such as GNSS augmentation services, seismic monitoring, and satellite orbit control.
