The GPS based shallow water high-precision positioning and navigation system has the beneficial effect of ability of effectively solving a problem of underwater positioning and navigation in a wide range, and has the advantages of simple structure, high positioning and navigation efficiency in a wide range and the like.
Description
Technical field
The utility model belongs to the Position Fixing Navigation System field, especially relates to a kind of shallow water hi-Fix navigational system based on GPS.
Background technology
Along with the demand of world economy and military developments, the research of modern marine new and high technologies such as marine resources development, marine energy utilization has become one of main field of world's new science and technology revolution.The ocean location navigation is the basis of all ocean development activities and the development of ocean hi-tech.
Location technology aspect under water, though developed Underwater Acoustic Positioning Systems such as long baseline, short baseline and ultra-short baseline, because these systems difficulty relatively aspect laying, safeguarding.And reach is limited, can't satisfy the requirement of the location navigation in big zone.
Summary of the invention
Problem to be solved in the utility model provides a kind of shallow water hi-Fix navigational system based on GPS, especially is fit to the navigator fix in marine site on a large scale.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of shallow water hi-Fix navigational system based on GPS, described Position Fixing Navigation System comprises that GPS buoy, Data Control Center, underwater transceivers, wireless data chain waterborne reach underwater sound data chain under water, described GPS buoy is connected with Data Control Center by wireless data chain waterborne, and described underwater transceivers is connected with Data Control Center by underwater sound data chain under water.
Further, described system comprises at least one GPS buoy.
Further, described GPS buoy is the self-floating anchored structure.
Further, described GPS buoy comprises GPS receiver, digital compass, data radio station, nautical receiving set, described GPS receiver is connected with data radio station, described digital compass is connected with data radio station, described nautical receiving set is connected with Data Control Center by underwater sound data chain under water, and described data radio station is connected with wireless data chain waterborne.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, can effectively solve on a large scale in the problem of location navigation under water, have simple in structure, on a large scale in location navigation efficient advantages of higher.
Description of drawings
Fig. 1 is structural representation of the present utility model
Embodiment
As shown in Figure 1, the utility model has comprised that GPS buoy, Data Control Center, underwater transceivers, wireless data chain waterborne reach underwater sound data chain under water, described GPS buoy is connected with Data Control Center by wireless data chain waterborne, and described underwater transceivers is connected with Data Control Center by underwater sound data chain under water.As shown in Figure 2, described GPS buoy is anchored structure, and all marine equipments all fixedly are arranged on the buoy, and buoy connects by wirerope and anchor chain, in order to the position of fixed buoy, makes it not move with ocean current and wind-force effect.The GPS buoy comprises GPS receiver, digital compass, data radio station, nautical receiving set.Described GPS receiver is connected with data radio station, and described digital compass is connected with data radio station, and described nautical receiving set is connected with Data Control Center by underwater sound data chain under water, and described data radio station is connected with wireless data chain waterborne.
The course of work below in conjunction with this example is further described the utility model: Data Control Center sends positioning request signal to underwater transceivers (being installed on carrier under water), underwater transceivers is after GPS buoy emission positioning signal, it is carried out time delay estimates, and result and gps data sent to data processing centre (DPC), data processing centre (DPC) draws the exact position of underwater transceivers according to above overall treatment.Underwater transceivers is received the request signal of a more than GPS buoy sometimes, and Data Control Center can automatic selection receives the buoy of request of underwater transceivers signal earlier as first-selection.Carry out large tracts of land when locating under water like this, only needing once configure according to the signal intensity of setting range and underwater transceivers position and the quantity of buoy, just can satisfy the needs of locating fully under water.Be specially adapted to the investigation in intensive area, large tracts of land subsea pipeline position.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
