Open Source C GPS Software for Linux

Viking is a free/open source program to manage GPS data. You can import, plot and create tracks, routes and waypoints, show OSM, Bing Aerial and other maps, geotag images, create routes using OSRM, see real-time GPS position (not in Windows), make maps using Mapnik (not in Windows), control items, etc. It is written in mostly in C (with some C++) & the GTK+3 toolkit. Viking is currently dual managed - with a corresponding Github presence at: https://github.com/viking-gps/viking Where you may find it easier to view the code and raise issues there too.

Provides user level applications and supporting library for getting GPS assistance data (such as satellite ephemeris and almanac) from SUPL server using SUPL/RRLP protocol over TCP/IP.

A Tcl Package to read and write Shapefiles

Experimental GPS navigation application for ultralight aircrafts, using as hardware a vehicular and inexpensive TomTom navigator. The program, given a GPX flight plan, is able to provide navigation indications using an HSI along the route up to the final destination.

The DTC (Drone Traffic Control) project for air traffic drones. It also utilizes DGPS for accurate position measurement of the drones.

A small server-side application is dedicated to provide TCP-packets response and basic logging functionality from operating low cost commercially available GPS Vehicle Trackers such as Concox GT06N and perhaps others (GT06E and GT06F). The application is using POSIX API and intended to run on Unix, Linux and even Windows systems (cygwin environment). Currently it has been developed and tested on FreeBSD 14.3. Recently added limited support for VL103 series devices from Jimi IoT Co., Ltd..

MerakoGPS is a set of software for Merako-series board aiming at GPS receiver development. MerakoGPS runs on a flexible Merako-series hardware board which uses a CycloneIII FPGA to accomplish the correlator function. see http://www.hyrising.com.

Open-Cell-Id-Visualization (OCIViz) ========================= Tools to visualize and analyze opencellid data. Create Googlemaps overlays and statistics. http://www.opencellid.org/ Contains (2013-06) >60million datasets of celltower information worldwide. This project wants to find out: * how much data was gathered where * quality of the coverage * what can you do with the data (localization etc.) For more information on what works and todos, see the project wikipage: https://sourceforge.net/p/ociviz/wiki/

This project is a reference, open source implementation of the coordinate conversion algorithms for the Polish geobotanical grid called ATPOL.

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.

A C library for parsing/normalizing street addresses around the world. Powered by statistical NLP and open geo data. libpostal is a C library for parsing/normalizing street addresses around the world using statistical NLP and open data. The goal of this project is to understand location-based strings in every language, everywhere. Addresses and the locations they represent are essential for any application dealing with maps (place search, transportation, on-demand/delivery services, check-ins, reviews). Yet even the simplest addresses are packed with local conventions, abbreviations and context, making them difficult to index/query effectively with traditional full-text search engines. This library helps convert the free-form addresses that humans use into clean normalized forms suitable for machine comparison and full-text indexing. Though libpostal is not itself a full geocoder, it can be used as a preprocessing step to make any geocoding application smarter, and simpler.
