int	pntpos (mrtk_ctx_t *ctx, const obsd_t *obs, int n, const nav_t *nav, const prcopt_t *opt, sol_t *sol, double *azel, ssat_t *ssat, char *msg)
	Compute receiver position, velocity, clock bias by single-point positioning with pseudorange and doppler observables.

Detailed Description

MRTKLIB Single-Point Positioning Module — SPP functions.

This header provides the standard single-point positioning function (pntpos), extracted from pntpos.c with zero algorithmic changes.

Note

Functions declared here are implemented in mrtk_spp.c.

ionocorr/tropcorr have been moved to mrtk_atmos.h / mrtk_atmos.c.

Function Documentation

pntpos()

int pntpos	(	mrtk_ctx_t *	ctx,
		const obsd_t *	obs,
		int	n,
		const nav_t *	nav,
		const prcopt_t *	opt,
		sol_t *	sol,
		double *	azel,
		ssat_t *	ssat,
		char *	msg )

Compute receiver position, velocity, clock bias by single-point positioning with pseudorange and doppler observables.

Parameters

[in]	ctx	Runtime context (NULL = use global)
[in]	obs	Observation data
[in]	n	Number of observation data
[in]	nav	Navigation data
[in]	opt	Processing options
[in,out]	sol	Solution
[in,out]	azel	Azimuth/elevation angle (rad) (NULL: no output)
[in,out]	ssat	Satellite status (NULL: no output)
[out]	msg	Error message for error exit

Returns

Status (1:ok, 0:error)
