Embodiment Construction
[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.
[0039] Figure 1a is a schematic diagram of the positioning terminal, Figure 1b It is a schematic diagram of the reference signal CRS in the communication system. Among them, such as Figure 1a As shown, the positioning terminal may be a communication and positioning composite terminal. The positioning terminal receives a reference signal through a positioning radio frequency channel, and the reference signal may be a common reference signal (CRS), and may receive a communication signal through a communication r...

The embodiment of the present invention discloses a position positioning, speed positioning method, device and positioning terminal, wherein the position positioning method includes: based on the time when the gateway station transmits a reference signal to the satellite and the time when the positioning terminal receives the reference signal forwarded by the satellite Determine the pseudo-range from the gateway station to the positioning terminal; wherein, the reference signal is a public reference signal in the communication network; determine the pseudo-range correction value from the satellite to the positioning terminal based on the pseudo-range and related parameters; determine the pseudo-range correction value, the positioning terminal Noise error, clock error of the positioning terminal, and the target relationship between the target geometric distance; among them, the target geometric distance is the geometric distance between the positioning terminal and the satellite; based on the position of the positioning terminal, the position of the satellite and the target geometric distance The relationship of and the target relationship determine the position of the positioning terminal. The technical solutions provided by the embodiments of the present invention can efficiently utilize precious orbital resources and frequency spectrum resources in space, and can realize high-precision positioning.
Description
technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a position positioning and speed positioning method, device, and positioning terminal. Background technique [0002] With the development of satellite technology, some terminals can rely on the existing satellite network to realize the functions of positioning, voice, and graphic communication, and can also realize communication with other devices. [0003] Among them, the terminal can perform navigation and positioning through the satellite navigation and positioning system, and can also communicate with other equipment through the satellite communication system. In the process, the above two systems need to be used respectively to realize positioning and communication. The orbital resources and spectrum resources in space cannot be effectively used, and the positioning accuracy is limited in the existing positioning process. Contents of the...
