The purpose of this project is to discuss basic idea of precise satellite positioning. When it comes to positioning area, GPS has been acknowledged to be the most popular concept. However, positioning signal is not simple as that. With this in mind, GNSS is actually the ultimate definition of positioning satellite. Global Navigation Satellite System (GNSS) refers to all constellations of satellite providing positioning signal from the space down to the Earth. Besides GPS developed by USA, GNSS includes Russia’s GLONASS, Europe’s Galileo and China’s Beidou Navigation Satellite System. Moreover, there are less utilized constellations such as Japanese QZSS, Indian IRNSS, etc. Mostly, GNSS signal has been utilized together with different types of protocol in order to increase precision of receivers. The two protocols are introduced in this paper is Precise Point Positioning and Real-time Kinetic (RTK). However, the more popular protocol RTK is analyzed more into details and an instruction has been given in order to build an RTK base station. RTK system helps receivers reach to precision of 1-3 centimeters offset. RTK system is extremely useful in autonomous off-road vehicle.
