![]() ![]() From all message standards that are use with GPS receivers, the NMEA 0183 is the most widely used messaging standard. In these messaging protocols, information can be transmitted as binary data (i.e., 1's and 0's) or using the ASCII character encoding. GPS receivers communicate using several "languages" or protocols, including standard and non-standard (i.e., proprietary) message formats. Typically, "GPS" is used as a general term for the overall equipment and process of using a GNSS to estimate position. This means that accuracy and precision of position, velocity and time data increases with more satellites. ![]() Globalnaya Navigazionnaya Sputnikovaya Sistema (GLONASS) from Russia.Ī minimum of four satellites from a GNSS are required to compute positions in three dimensions and the time offset in the receiver clock.Quasi-Zenith Satellite System (QZSS) from Japan.European Global Navigation System (Galileo) from Europe.Navigation Indian Constellation (NavIC) from India.BeiDou Navigation Satellite System (BDS) from China.While the Global Positioning System (GPS) from the United States is the most widely GNSS used in the world, other GNSS are also available, including: A GNSS is a group, or constellation, of 24, or more, satellites working together to provide positioning and timing services globally under any weather conditions. Our smartphones can do this with the help of a chip that communicates with a group of satellites in the sky, collectively known as a Global Navigation Satellite System (GNSS). With the help of a smartphone, we can know where we are on the earth to a few meters. ![]()
