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.

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).
gpsd is a computer software program that collects data from a Global Positioning System (GPS) receiver and provides the data via an Internet Protocol (IP) network to potentially multiple client applications in a server-client application architecture.
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.
GNSS-2 is the second generation of systems that independently provide a full civilian satellite navigation system, exemplified by the European Galileo positioning system. [5] These systems will provide the accuracy and integrity monitoring necessary for civil navigation; including aircraft.

RTCM Version 3, initially released in February 2004, [5] is the current and continually evolving version of the RTCM standard. In contrast to 2.3, version 3.x uses a variable-length message format and a single 24-bit cyclic redundancy check (CRC) on the entire message as opposed to a 6-bit parity for every 30-bit word.
