What is a GNSS satellite Navigation
GNSS (Global Navigation Satellite System) or SSNG (Global navigation satellite system) equipment are the acronyms that are used to group the different systems of navigation satellite providing global coverage a positioning geospatial in an autonomous manner.
This concept brings together different systems such as GPS, Glonass, Galileo and Compass among others, allowing very precise positioning based on signals emitted by these satellites being multiple applications such as the geo information or geoscientific investigations.
These Global positioning systems are passive navigation systems based on RF emissions of satellite broadcasters which provide a spatio-temporal reference regardless of the weather conditions of the now, all this anywhere Earth and continuously. The system consists of a network of satellites, radio bases land and receiving GPS that allow almost all possibilities of navigation and positioning anywhere in the world at any time regardless of the weather conditions.
This complex system is composed of:-GPS systems – System of land Control – User system
