What is a GNSS receiver

What is a GNSS receiver

1. The function of the receiver

  The receiver is an integral part of the communication satellite navigation system. It receives signals from communication satellites and processes the received data signals to obtain positioning.

  The signal is sent by a part of the indoor space (indoor space twelve constellations) and a part of the ground (road monitoring station). Because the communication satellite is constantly moving in the air, it is very difficult for the road monitoring station to measure its position. Therefore, in order to obtain reliable positioning conclusions, it is necessary to install several receivers in the air or on the ground, and constantly receive data signals sent by communication satellites.

  Among the navigation methods, GPS communication satellite positioning system, GLONASS, and GALILEO communication satellite positioning system have become the three commonly used communication satellite navigation and positioning systems at present. They all use pseudo-range testing technology to measure the user's position.

Second, the basic principle of GPS positioning

  The GPS positioning system uses accurate measurement of the distance between the communication satellite and the user receiver to clarify the user's location. When operating, the user first establishes a positioning point (usually a measuring point), and imports the coordinates of the position to which he belongs to the positioning point. Then install 2 or several GPS receivers on the workstation, and determine the distance from the other receiver to the measuring point by measuring the distance between one of the receivers and the measuring point. When the middle distance between the two receivers is clear, use these two distances to calculate the distance between the user and the GPS communication satellite. After precise measurement, the user's location information can be obtained.

3. Main purposes of hydrology

  Water regime monitoring: GNSS can be used to detect water level information such as water level and total flow of water conservancy construction projects such as rivers and water conservancy projects, and immediately risk early warning to solve many problems such as abnormal water level lines.

  Water conservancy and hydropower projects: GNSS can be used to build water conservancy and hydropower projects, such as embankments, water conservancy hubs, gates, etc., to ensure the safety of water conservancy construction projects.

  Water resources protection: GNSS can be used to manage water conservancy construction projects, such as water conservancy hubs, rivers, etc., and specifically guide the development and utilization of water conservancy resources.

  Hydrological detection: GNSS can be used to detect hydrological information such as river platform flow, water level, rainfall, etc., and immediately risk early warning to solve hydrological anomalies.

  Water conservancy project informatization: GNSS can be used in basic construction of water conservancy project information system software, such as water conservancy project database system, water conservancy project information data sharing platform, etc., to improve the efficiency and effectiveness of water conservancy work.
