Miniaturized dynamic trajectory high-accuracy testing device

Abstract

The invention discloses a miniaturized dynamic trajectory high-precision testing device. The first structure includes a communication antenna, a communication module, a positioning module, a power supply, a memory, and a positioning antenna; the communication module, the memory, and the positioning antenna are all connected to the positioning module, and the communication The antenna is connected with the communication module, and the power supply supplies power to each component. The second structure includes an air part and a ground part. The air part includes a radio module, a communication antenna, a positioning module, a power supply, a memory and a positioning antenna; the communication antenna, the memory and the positioning antenna are all connected to the positioning module, and the radio module is connected to the communication antenna. The power supplies power to each component; the ground part includes the RTK base station with a built-in radio or the RTK base station with an external radio, and the radio communicates with the radio module. The invention has the advantages of simple structure, small volume and light weight, and meanwhile, the positioning antenna and the RTK base station can realize centimeter-level positioning.

Description

technical field [0001] The invention relates to a miniaturized dynamic trajectory high-precision testing device, which belongs to the field of positioning devices. Background technique [0002] In recent years, with the strong support of the state, the Beidou satellite navigation system has developed rapidly. In the field of positioning and navigation, aerial positioning and navigation aircraft, especially unmanned aerial vehicles, have begun to emerge in the civilian market. At the same time, it also exposed the problem of insufficient supervision. The country is stepping up the introduction of a series of control measures. Considering that drones, especially consumer aircraft such as aerial photography, have the characteristics of small size and light load, how to use high-precision positioning equipment to evaluate the performance of aircraft under high-altitude flight has become a problem. Most of the existing high-precision equipment in China is geodesic equipment, wh...

Problems solved by technology

Most of the existing domestic high-precision equipment is geodesic equipment, which is large in size and weight and cannot be used on small drones. This urgently requires a portable device with light weight, small size, superior dynamic positioning performance, and stability. As a flight performance test equipment for aerial vehicles such as drones
