Navigation method for flowing object based on GPS tracking

Abstract

The invention relates to the technical field of object tracking, in particular to a navigation method for a flowing object based on GPS tracking. The method comprises the steps of digital signature: signing a flowing object through a digital message, and embedding a positioning unit in the signature, wherein the positioning unit is used for positioning the position information of the flowing object; signal receiving: receiving a position signal of the flowing object of the positioning unit; signal measurement: measuring the received position signal by using a navigation unit, and calculating the three-dimensional position of the flowing object; and position query: performing real-time query on the position of signal measurement so as to timely obtain the digital signature of the position of the flowing object. The flowing object is signed by using the digital message, the positioning unit is embedded in the signature, and the positioning unit is used for positioning the position information of the mobile object, so that the mobile object is accurately positioned, and meanwhile, the feature information and the position information of the mobile object can be known through query.

Description

technical field [0001] The invention relates to the technical field of object tracking, in particular to a navigation method for floating objects based on GPS tracking. Background technique [0002] At present, the Global Positioning System (GPS) is a high-precision radio navigation positioning system based on artificial earth satellites. It can provide accurate geographic location, vehicle speed and precise time anywhere in the world and in near-earth space. information. Since its inception, GPS has attracted many users with its high precision, all-weather, global coverage, convenience and flexibility. GPS is not only the patron saint of cars, but also the wisdom of logistics industry management. With the rapid development of the logistics industry, GPS plays a pivotal role and becomes the second major consumer group after the automobile market.

Problems solved by technology

[0003] However, in many cases, the mobile objects are fixed with the location information of the car and cannot be accurate to each object. If the object in the car is lost or omitted, the location cannot be obtained, so the receiver and sender must bear the loss of the loss, and the object cannot be returned.
