Embodiment Construction

[0032] The invention provides an on-site target positioning system, which includes an unmanned aerial vehicle system and a control system. Among them, the UAV shoots and returns the on-site image; the control system identifies and accurately superimposes the on-site image data on the original terrain database collected by the satellite in the early stage, and automatically generates the coordinates of the on-site image; the output module converts the processed on-site image and its coordinates are transmitted to the command center. NSSPS operators discover and transmit images and coordinates of target personnel, equipment or facilities to the command center through the positioning screen.

[0033] The specific implementation method can refer to the following methods:

[0034] 1. Establish the original terrain database

[0035] 1) Use satellites to collect raw topographic maps;

[0036] 2) Establish the original terrain database.

[0037] 2. Control system settings

[0038...

Abstract

The invention relates to a positioning system without satellite support. The positioning system without satellite support is a remote sensing measuring system used for accurate positioning on target people, equipment, or facilities, and comprises an unmanned plane and a control system. A method comprises following steps: an original landform database collected using a satellite at an early stage is adopted to establish an on-site coordinate system in the control system; the unmanned plane is used for taking and sending on-site images; the control system is used for identifying the on-site images, and realizing accurate stacking of image data onto the original landform database, so that on-site image coordinates are generated automatically; when target people, equipment, or facilities are detected, the control system is used for sending the related images and coordinates to a command center. The positioning system without satellite support is capable of providing real-time on-site images at the same time.

Description

technical field [0001] The invention relates to remote sensing measurement, in particular to a system for precise positioning of target personnel, equipment or facilities in the absence of satellite support. Background technique [0002] In the civilian and military fields, the application of satellite positioning technology is more and more extensive. [0003] With the support of satellites, the technology of using UAVs for remote sensing measurement is also becoming more and more perfect and reliable. It is mostly used for measurements in areas that are difficult to cover by satellites, precise measurements under special requirements, and so on. However, without the support of satellites (such as satellite equipment failures, communication failures, or technical failures, etc.), the accuracy of drone measurements is limited. [0004] In modern warfare, the use of military satellites is equally important. Compared with countries without military satellites, countries with...
