Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. Such as figure 1 As shown, the present invention includes three parts: a landmark 1, a terminal 2 and a monitoring center 3. The landmark 1 is arranged on the ground or near the ground of all places where its coordinate position needs to be clarified or has a prompt meaning, and the terminal 2 is placed on the carrier 4. ,in

[0036] 1. Landmark 1 consists of the following parts (see figure 2 ):

[0037] (1) Antenna 11:

[0038] It is used to receive work instructions and energy radiation from the terminal 2, and transmit the attribute information 110 of the landmark 1 on the transmission carrier frequency. The antenna 11 can also be set independently according to the receiving antenna and the transmitting antenna.

[0039] (2) Modem 12:

[0040] The commands received from the terminal 2 are demodulated and the transmitted landmark codes ar...

Abstract

A multifunctional ground positioning system is composed of ground beacons, terminals and monitor center. Said beacon contains its attribute information, powered by external radiation and arranged at the desired point on ground. Said terminal installed on moving carrier can excite said ground beacon to receive its attribute information and obtain the coordinate and navigation information after its internal processing. Its advantages are high positioning precision, and low cost.

Description

technical field [0001] The invention relates to a positioning system, in particular to a multifunctional ground positioning system. Background technique [0002] If people need to determine the orientation of their location, they generally use GPS terminal devices. This device is used to simultaneously receive the same-frequency signal parameters of 3 to 4 satellites among the 21 dedicated satellites launched by the US military, and obtain the real-time positions of these satellites in space and the unified time when sending signals after demodulation. Its built-in calculation unit obtains the earth's longitude, latitude and altitude of the location according to complex processing methods. The characteristic of this system is that precise coordinate values ​​can be obtained in real time anywhere in the world. However, because the GPS system uses the microwave frequency band to send positioning information, microwaves have the characteristic of traveling in a straight line ...
