goGPS MATLAB 0.4.3

goGPS MATLAB version 0.4.3 is available for download. This is mainly a release to fix a bug that emerged since version 0.4.2: if the rover RINEX file contained approximate coordinates in the header, these were used as approximate coordinates for each processing epoch, also for kinematic datasets. If the rover moved farther away than 30-40 […]

goGPS MATLAB 0.4.2

goGPS MATLAB version 0.4.2 is available for download. Main changes introduced since v0.4.1beta: Core: Added an outlier detection and removal method based on a Leave-One-Out (LOO) procedure (it’s applied to all Least-squares and Kalman filter solutions) Added the use of antenna PCO/PCV to correct phase observations Input: Added support for NVS receivers (with GPS, GLONASS, […]

goGPS MATLAB 0.4.1beta

goGPS MATLAB version 0.4.1 beta is available for download. This is mainly a bug-fix release to improve compatibility with new MATLAB versions (starting from R2013). Changelog since v0.4.0beta: Core: Ionospheric delay inter-frequency factor is now properly computed and applied for all the multi-GNSS frequencies. Input: Antenna offset in the header of RINEX files is now […]

goGPS Java v1.0.2

A new version of goGPS Java (1.0.2) has been released. Changelist: – Added a check on satellite health – Added a method to write a text file output with the processing results (same format as goGPS MATLAB) – Added the source code of a command line application (org.gogpsproject.apps.LogUBX) for logging UBX binary data from one […]

goGPS MATLAB 0.4.0beta

goGPS MATLAB version 0.4.0beta is available for download. Main changes introduced since v0.3.1beta: Core: Added support for EGNOS corrections in stand-alone mode, using the EMS service. Requires an active Internet connection or to download EMS files beforehand. Added integer ambiguity resolution by LAMBDA method; both LAMBDA v2 and v3 can be used (MATLAB code published […]

goGPS MATLAB v0.3.1beta

goGPS MATLAB version 0.3.1 beta is available for download. Changelog since v0.3.0beta: Core: Fixed an error in the satellite orbit computation that was introduced with v0.3.0beta (the relativistic term was being applied after the orbit computation) Added observations reading and processing at rates other than 1 sec (post-processing only; ‘INTERVAL’ keyword in RINEX header is […]

goGPS MATLAB v0.3.0beta

goGPS MATLAB version 0.3.0 beta is available for download. A summary of the main changes since v0.2.0beta: Core: Re-structured the core functions for: improving the satellite orbits computation by iterative least squares adjustment together with receiver position and clock optimizing the code by removing duplicate function calls and unnecessary ‘for’ cycles (computation speed improved by […]

goGPS Java v1.0.1

A new version of goGPS Java (1.0.1) has been released to address a bug involving incomplete KML files in output.

goGPS Java

The first official release of goGPS Java is available for download. Currently it is provided as a library implementing the core functions of goGPS MATLAB. It can work either in post-processing by reading observations from RINEX or UBX files or real-time by acquiring raw data from a u-blox receiver connected to a USB/serial port and […]

goGPS v0.2.0beta

goGPS version 0.2.0 beta is available for download. A summary of the main changes since v0.1.2alpha: Core: Added satellite velocity computation Added integrated Doppler shifts computation Added optional Doppler-based phase range prediction for detecting cycle slips Modified the structure of Kalman filter functions (improved new satellites / cycle slip management) Added the possibility to select […]
