Detailed Description

MRTKLIB MADOCA-PPP Module — QZSS L6E CSSR message decode functions.

This header provides functions for decoding QZSS L6E (MADOCA-PPP) Compact SSR messages and converting them to RTCM SSR format, extracted from mdccssr.c with zero algorithmic changes.

Note: Functions declared here are implemented in mrtk_madoca.c.

Definition in file mrtk_madoca.h.

Function Documentation

◆ decode_qzss_l6emsg()

int decode_qzss_l6emsg ( rtcm_t * rtcm )

Parameters

[in,out] rtcm RTCM control struct

Returns: Status (-1: error, 0: no message, 10: input SSR messages)

Note: Before calling this function, call init_mcssr().
