# rnx2rtkp(1)

read message log files and computer receiver positions

## NAME

rnx2rtkp - read message log files and computer receiver positions

## SYNOPSIS

rnx2rtkp \[option ...\] file file \[...\]

## DESCRIPTION

Read RINEX OBS/NAV/GNAV/HNAV/CLK, SP3, SBAS message log files and compute receiver (rover) positions and output position solutions. The first RINEX OBS file shall contain receiver (rover) observations. For the relative mode, the second RINEX OBS file shall contain reference (base station) receiver observations. At least one RINEX NAV/GNAV/HNAV file shall be included in input files. To use SP3 precise ephemeris, specify the path in the files. The extension of the SP3 file shall be .sp3 or .eph. All of the input file paths can include wild-cards (\*). To avoid command line deployment of wild-cards, use "..." for paths with wild-cards. Command line options are as follows (\[\]:default). With -k option, the processing options are input from the configuration file. In this case, command line options precede options in the configuration file.
