Problems solved by technology

[0011] However, in order to use DGPS, expensive DGPS receivers and additional transmitters must be used, and many mobile stations are operated, which unnecessarily increases costs
In order to reduce the above additional costs, a post processing DGPS (Post processing DGPS) scheme is proposed, but this scheme is not suitable for real-time processing and has serious defects

[0081] In the above example, "AAA" and "ABB" are "information headers", which are separated by the discriminator "-". That is: in the case of example 1), the data string of the location data is listed, the GPS number is listed after the first specifier, and the local area coordinate value of the position to be displayed is listed after the second specifier . In contrast, in the case of example 2), the data string of the task control server data is listed, and the type of the task is indicated after the identifier.

[0082] The above detailed description shows that the existing position recognition system GPS has a large error, and DGPS must be equipped with expensive equipment, which is not easy for users in industrial sites to choose.

[0083] In particular, DGPS, which overcomes the huge error range of GPS, still depends on the distance of the reference station. In order to improve its accuracy to the expectation of precise position rec...

Abstract

A position identifying system, includes an abbreviated base station (10) having a base station GPS receiver (11) with a predetermined position, a moving station GPS receiver (31) for determining the position by the satellite, a first radio MODEM (32) for transmitting GPS signal comprising a position parameter and satellite time parameter from the moving station GPS receiver and a moving station (30) therebetween, a second radio MODEM (43) for carrying out close-distance radio communication with the first radio MODEM (32), a server (41) for identifying the position, and a central control server (42) and a central control center (40) therebetween. In the central control server (42), the server (41) for identifying the position calculates a correcting value, based on the position parameter transmitted from the moving station (30) to the moving station in the GPS signal, correcting the error to produce the correct parameter of the actual position of the moving station.

Description

technical field [0001] The invention relates to a technology for real-time position recognition of a mobile object (mobile base station) in a local area (with a radius of about 1-several kilometers). Background technique [0002] In the past, there was a bias in the development of new products in the industry, but in recent years, the development of new products has been given priority in the leading industries, and the existing products should also be intelligent, automated, and simplified. From this point of view, GPS (Global Positioning System), which is a position recognition technology for mobile objects, will definitely become an important technology for improving existing industries. [0003] GPS receives parameters about position, speed and time from at least 4 satellites through a receiver, and is a system that can identify the position of a mobile station. However, GPS is subjected to satellite orbit, ionospheric delay, tropospheric delay, and intentional error op...
