Embodiment 1
[0028] Such as Figure 1-3 As shown, a method for improving the accuracy of navigation mark positioning by using partitioned networking includes the following steps:
[0029] Step 1. First, divide the water area to be located according to the water area. First, divide it into several medium-sized areas, and then divide each medium-sized area into several small areas; Base station equipment; when there is no base station equipment in the medium-sized partition, then select a suitable fixed position in the medium-sized partition and install a base station equipment; the base station equipment automatically calculates the positioning deviation, generates differential correction parameters and It is transmitted to the remote server through the 3G communication module;
[0030] Step 2, installing a positioning device in each small partition; the positioning device includes a master device and more than one slave device; wireless data transmission is performed between the master de...

The invention discloses a method for improving navigation mark positioning precision through sub-area networking. The method includes the steps that step1, firstly, according to water area conditions, a water area is divided into multiple middle-sized sub-areas and then divided into multiple small sub-areas, and then reference station equipment is installed in each middle-sized sub-area and used for generating difference deviation correcting parameters; step2, a positioning device is installed in each small sub-area and comprises main equipment and one or more auxiliary equipment, and the main equipment is in communicated with the auxiliary equipment through wireless local area networks; step3, the main equipment receives the difference deviation correcting parameters issued by a remote server and transmits the parameters to the auxiliary equipment, the main equipment and the auxiliary equipment correct own positioning data, and then the data are uploaded to the remote server through the main equipment. High cost for establishing a CORS difference station can be reduced, the same positioning effect can be achieved, burdens of the server and network communication cost can be reduced through sub-area networking, and power consumption of the auxiliary equipment can be lowered.
Description
technical field [0001] The invention relates to a positioning technology, in particular to a method for improving the positioning accuracy of navigation marks by using a partitioned network; it is mainly applied to the control and positioning of navigation marks in inland waterways and coastal waterways. Background technique [0002] Now, GPS satellite positioning technology has been well applied in many industries, and the positioning accuracy of ordinary civilians has reached about 10 meters. If differential technology is used, it can be raised to about 5 meters. However, the positioning accuracy of 5 meters is far from enough for the positioning requirements of natural waterways. In natural waterways, the channel is often very narrow, and the ship often sails against the rocks beside the channel, especially in some dangerous shoals. Therefore, the positioning accuracy of 5 meters often cannot meet the needs of waterway management and ship navigation, and it is necessary ...
