The units of a correlator, an adjuster, a processing IC unit and the like are reduced, and therefore, the volume is small, the power consumption is low, the structure is simple and the cost is low, and furthermore, the utility model can have a more extensive application scope.
Description
Technical field
The utility model relates to the navigator field, particularly a kind of USB location navigation device.
Background technology
The satellite navigation system that formally puts into operation in the world at present has " No. one, the Big Dipper " three big systems of GPS of USA, Muscovite GLONASS and China, but really reaches the GPS that has only of industrialization level.It with distinguishing features such as round-the-clock, high precision, robotization, high-level efficiency and many-sided power such as unique location navigation, time service calibrating frequency, precision measurement, the application that involved is numerous makes the gps satellite navigational system become the 3rd IT point of economic increase in the whole world after cellular mobile communication one internet.
The satellite positioning navigation product all is used widely in the civil and military field at present, when seeing huge market potential, each GPS location navigator manufacturer and consumer pursue the more location navigation device of low price, but the location navigation device of prior art is owing to comprise correlator, regulator, baseband processing unit, analog radio frequency IC and USB interface switching controller etc., complex structure, cost height have limited usable range.
The utility model content
The utility model provides a kind of simple in structure, USB location navigation device that cost is low.
USB location navigation device provided by the utility model is achieved through the following technical solutions:
A kind of USB location navigation device comprises antenna element, radio frequency unit and interface unit, and described radio frequency unit is connected with interface unit, and described antenna element is connected with described radio frequency unit, wherein:
Described antenna element is used to receive gps signal, and described gps signal is sent to radio frequency unit;
Described radio frequency unit is used to receive the gps signal that described antenna element sends, and described gps signal is handled the back send to described interface unit;
Described interface unit is used for the gps signal that the received RF unit sends, and described gps signal is sent to external equipment after transforming.
According to above-mentioned principal character, described interface unit also comprises expansion interface, is used for being connected with other external equipments, expands described USB location navigation device.
According to above-mentioned principal character, described radio frequency unit also comprises antennal interface, is used for the strong antenna assembly of outer signal receiving ability.
From technique scheme as can be seen, the USB location navigation device that the utility model provides is owing to only comprise antenna element, radio frequency unit and interface unit, reduced correlator, regulator, baseband processing unit, etc. the unit, thereby volume is little, low in energy consumption, simple in structure, cost is low, thereby can be more widely used.
Description of drawings
The structure principle chart of the USB location navigation device that Fig. 1 provides for the utility model.
Embodiment
In order better to understand the technical solution of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.
