Embodiments of the present application provide a target detection method, system, and equipment based on navigation satellite signals. The target detection method based on navigation satellite signals includes: the missile-borne equipment obtains the first original observation of the navigation satellite signal; The device sends the first parameter information carrying the first raw observation, wherein the first parameter information is used by the receiving device to determine the position of the projectile equipped with the missile-borne device, so that the receiving device can determine the miss-target amount of the projectile. The missile-borne equipment on the shell in the embodiment of the present application does not need to locate itself, it only needs to send the acquired first original observation to the receiving device, and the receiving device determines the position of the shell. Based on the GPS measurement system, the missile-borne equipment on the shell in the embodiment of the present application does not need to perform a positioning process, thereby realizing fast positioning, and further solving the problem of long positioning time existing in the existing missile-borne equipment.
Description
technical field [0001] The present application relates to the field of shell target detection, in particular, to a target detection method, system and equipment based on navigation satellite signals. Background technique [0002] At present, in the target detection process of the shell, the existing GPS (Global Positioning System, Global Positioning System) measurement system on the shell needs to add ephemeris information before the shell is launched, and after the shell is launched, the bomb-borne equipment on the shell still needs to be added. The process of searching, receiving and positioning is required, that is, the on-board equipment on the shell is required to realize the positioning of the shell, and then send the position of the shell to the receiving device. [0003] However, in the above solution, the positioning of the projectile can only be realized after the missile-borne equipment needs to perform multiple steps. Therefore, the existing missile-borne GPS me...
