An open source software-defined Global Navigation Satellite Systems (GNSS) receiver written in C++ and based on the GNU Radio framework.

Eagleye is an open-source software for vehicle localization utilizing GNSS and IMU[1]. Eagleye provides highly accurate and stable vehicle position and orientation by using GNSS Doppler[2][3][4][5][6]. The flowchart of the algorithm is shown in the figure below. The algorithms in this software are based on the outcome of the research undertaken by the Machinery Information Systems Lab (Meguro Lab) at Meijo University.

* Please check latest update on https://github.com/igps-ftk/iGPS A tool written in Interactive Data Language (IDL), for processing and analyzing daily continuous GPS position time series. It can read time series in various formats, detect outliers, remove abnormal observation spans, find jumps, extract common-mode components(CMC), etc.

NMEA_ZDA_TO_UTC Insertion du message $UTC avec correction en temps réel du décalage avec le signal PPS. Permet de bien faire fonctionner certains équipements qui demande le message $UTC d'Applanix, mais en utilisant un GPS générique. Le point décimal de l'heure UTC compensée dans le message $UTC est synchro à ± 0,5 mS avec l'heure réelle UTC. Vous pouvez donc vous servir de ce repère comme d'un émulateur du signal PPS bon marché. Ce n'est pas un signal au TOP de la seconde (!...

NaveGo is an open source MATLAB/GNU Octave toolbox designed for processing integrated navigation systems, simulating inertial sensors and GNSS receivers, and profiling inertial sensors using methods like Allan variance—providing a community-driven simulation framework for navigation system design and analysis. I am reaching out to share an important update regarding the NaveGo project. Due to a shift in both my professional career and personal interests away from navigation systems, I have made the difficult decision to step down from my role as the lead developer of NaveGo. ...

RTKLIB is an open source program package for standard and precise positioning with GNSS (global navigation satellite system). RTKLIB consists of a portable program library and several APs (application programs) utilizing the library. This port includes only a library (.so or .dll) for the C/C++ language and a .dll for C#/.NET Framework. RTKSharp is compatible with Windows and Linux using the .NET/Mono Assembly withoout the need of recompilation/cross-building.

GeoNet is a software to perform rigorous least squares adjustment of topographic (Total station, GNSS and levels) observations directly in a global reference frame.

GSAC is web services for discovery of instrumented site information, and of instrument data files, available in an archive, to provide site and instrument information in a variety of standard formats (RINEX, XML, csv, GAMIT, SINEX, Json, png, ...), and to show where (URLs) to download instrumental data and derived-product files. GSAC is intentionally built to handle many kinds of Earth science data from instruments with Earth locations, and derived products from such data. For example, GNSS receivers for geodesy, tide gages, met stations, tiltmeters, strainmeters. GSAC is installed at 7 data centers in the Americas and 6 in Europe. One agency's GSAC enables search and access across more than 12,800 GPS stations for more than five million data files. This SF website appears to be all about the (minor) helper program, the GSAC client. ...

goGPS MATLAB is an advanced GNSS observation processing software.

NovaRS - software for control GNSS station equipped with NovAtel receivers. Programm can generate on-the-fly hourly and daily RINEX 2.11 files according to IGS naming conventions.

GPS 1A sampler. This command-line utility is compatible with the GPS Creations GPS 1A USB receiver and streams IF samples to file. Command line arguments are: Filename (including extension and full/relative path) RecordDuration (in sec, eg. 100.0 ).

This work presents an objected oriented system design and modeling (OOSDM) framework for reliable and flexible system design. *Can generate raw signals at desired IF. *Use GPSTk Libraries * Allow multiple receiver simulation * 12 Channels

Post-processing navigation software for raw GPS/GNSS receiver data (pseudorange, Doppler, and carrier phase data) in stand-alone, and differential mode. Portable C foundation code. C++ for more advanced apps. NovAtel OEM4 and RINEX supported.

The Open Source GNSS Reference Server (OSGRS) is a HTTP server that provides data for Assisted-GNSS applications. It caches the data and then provides it to the A-GNSS client over the GNSS Reference Interface Protocol (GRIP) on request.
