The essence of satellite-to-satellite tracking (SST) technology is to measure the distance change between two satellites with high resolution. The former category is high-orbit satellites (such as...
GPS Outlook Due to the characteristics of all-weather, high-precision and automatic measurement of GPS technology, as an advanced measurement method and new productivity, it has been integrated int...
24 GPS satellites operate at an altitude of 20,200 kilometers above the ground, making it possible to observe more than 4 satellites simultaneously at any point on the ground at any time. Since t...
GPS application The application of gps global satellite positioning and navigation system in the civil field, in addition to the professional application field, with the requirements and improvemen...
GSP composition features The global positioning system consists of three parts: (1) the ground control part, which consists of the main control station (responsible for managing and coordinating th...
In the GPS application, the orbit error mainly affects the positioning accuracy in the early stage, and the early GPS baseline is relatively short and the height difference is not large, so the re...
The application of GPS in monitoring the ionosphere is also the beginning of GPS space meteorology. Space is full of plasma, cosmic ray particles, and electromagnetic radiation of various bands. B...
