A software GNSS receiver is a Global Navigation Satellite System (GNSS) receiver that has been designed and implemented using software-defined radio.. A GNSS receiver, in general, is an electronic device that receives and digitally processes the signals from a navigation satellite constellation in order to provide position, velocity and time (of the receiver).
However, in many cases, it is also that which makes the program free (and sometimes open source [1]), avoid the need of an Internet connection, [2] [3] [4] and make it very lightweight (allowing use on small portable devices, including smartphones). Very basic programs like this may not be suitable for road navigation in cars, but serve their ...
The OpenHPSDR (High Performance Software Defined Radio) project dates from 2005 when Phil Covington, Phil Harman, and Bill Tracey combined their separate projects to form the HPSDR group. [1] It is built around a modular concept which encourages experimentation with new techniques and devices (e.g. SDR , Envelope Elimination and Restoration ...
Satellite navigation solution for the receiver's position (geopositioning) involves an algorithm.In essence, a GNSS receiver measures the transmitting time of GNSS signals emitted from four or more GNSS satellites (giving the pseudorange) and these measurements are used to obtain its position (i.e., spatial coordinates) and reception time.
Hardware-wise, a GNSS receiver is needed to interpret satellite signals and compute the user’s location. Nowadays, it is usually a single integrated circuit (IC).. Satellite navigation software is most commonly used on mobile devices, particularly mobile phones, to provide the positioning functionality.

The Transient Array Radio Telescope (TART) is a low-cost open-source array radio telescope consisting of 24 all-sky GNSS receivers operating at the L1-band (1.575 GHz). TART was designed as an all-sky survey instrument for detecting radio bursts, as well as providing a test-bed for the development of new synthesis imaging and calibration ...
GNU Radio is a free software development toolkit that provides signal processing blocks to implement software-defined radios and signal processing systems. It can be used with external radio frequency (RF) hardware to create software-defined radios, or without hardware in a simulation-like environment. It is widely used in hobbyist, academic ...
