Detailed Description

MRTKLIB Precise Point Positioning (PPP) Module.

This header provides the PPP positioning functions including the main PPP filter (pppos), number-of-states query (pppnx), and solution status output (pppoutstat).

Note

Functions declared here are implemented in mrtk_ppp.c.

Definition in file mrtk_ppp.h.
