Joel Barnes' Satellite Positioning and Geodesy Resources

Information and Data

• Archive of NANUs in compact format from 1994.
• Archive of CANSPACE mailing list from 1989.
• Current format specfications for RINEX, SINEX and SP3 from IGSCB
• GPS calendars from GIBS and IGSCB
• GPS antenna calibration information from NOAA

• Free GPS processing software and source code for pseudo-range-based positioning by Leeuwen and Johnston.
• Java applets demonstrating SA, DOP and C/A code.
• Free Matlab based routines for deformation modelling, including Mogi, discolations and optimisations using simulated annealing by Cervelli.
• Free Matlab based routines for GPS processing by Kai Borre.
• The GPS Toolbox - The main purpose of the site is to provide a means for distributing the source code and algorithms, as discussed in the GPS Toolbox column of the journal 'GPS solutions'.
• Auto GIPSY Precise Point Positioning Service, from JPL, California Institute of Technology. A free ftp/email based service that estimates precise point coordinates of a single site using the GIPSY/OASIS-II (GOA-II) software.
• SOPAC Coordinates Generator, from Scripps Orbit and Permanent Array Center. A free web/ftp based service that estimates the coordinates of a single site using the GAMIT software and IGS tracking.
• SOPAC GPS Date Converter, from Scripps Orbit and Permanent Array Center. Converts between various data formats.
