GpsTools (GT) is a precise analysis software package for GPS/GNSS data based on MATLAB. GT provides the functions of:
- Estimation of precise receiver positions by static PPP (precise point positioning)
- Estimation of precise receiver motion by kinematic PPP
- POD (precise orbit determination) of GPS satellites
- Estimation of precise clock-bias of GPS satellites
- POD of LEO (low earth orbit) satellites by kinematic PPP
- Estimation of tropospheric parameters as ZTD (zenith total delay) or PWV (precipitable water vapor)
- Precise time transfer between receivers by PPP
- Many graph plots for the estimation results or GPS/GNSS related data
- GUI for parameter settings and execution of analysis
- Analysis with dual-frequency GPS/GNSS carrier-phase and code measurements
- Extended Kalman Filter/Smoother for parameter estimation
- Embedded precise models, including GPS/GNSS measurements, atmospheric correction and satellite motion
- Support of many standard formats for GPS/GNSS data like RINEX, SP3, SINEX, IONEX, IERS, IGS, BLQ, ANTEX
- Common MATLAB libraries callable by user application programs
