Abstract
The utility model provides an ocean measuring -signal long distance transmission device, relates to communication field signal transmission device technical field. Include outdoor choke coil antenna and indoor external radio station, GNSS reference station receiver, connect the GNSS ANT serial ports and the DLPW1 serial ports of choke coil antenna end mouth and GNSS reference station receiver and the D data port in external radio station of GNSS reference station receiver through the cable respectively, wherein, GNSS reference station receiver and external radio station insert the direct current. Have that signal transmission distance is far away, the positive effect of the accurate location of RTK of being convenient for.
Description
Technical field
This utility model is related to communication field signal transmission apparatus technical field, especially belongs to a kind of Ocean Surveying signal
Long distance transmitter.
Background technology
When carrying out operation on the sea in sea area, positioning measurement need to be carried out by RTK.RTK measurement on the market at present
Orientation distance is less than 10 kilometers, and general ocean engineering job site apart from land base station distance more than 10 kilometers, because
This existing equipment cannot meet remote Ocean Surveying location requirement.
Content of the invention
The purpose of this utility model is to provide a kind of Ocean Surveying signal long distance transmitter, practical, can
High by property, to reach the purpose realized sea area signal long-distance transmissions and be easy to marine measuring point positioning operation.
Ocean Surveying signal long distance transmitter provided by the utility model is it is characterised in that include outdoor gripping
The plug-in radio station of stream circle antenna and interior, GNSS reference receiver, connect GNSS reference receiver respectively by cable
GNSS ANT serial ports and choke coil antenna port and GNSS reference receiver DL/PW1 serial ports and plug-in radio station D number
According to port, wherein, unidirectional current is accessed in described GNSS reference receiver and plug-in radio station.
Preferably, described GNSS reference receiver is VNET6 type receiver.
Ocean Surveying signal long distance transmitter provided by the utility model, by choke coil antenna, GNSS benchmark
Stand receiver, receive domestic satellite-signal, and the data calculation function through GNSS reference receiver, by defending of receiving
Star signal processing becomes differential signal, and the strength of differential signal because obtaining is weaker, need to pass through high-power plug-in radio station, increases difference letter
Number intensity, then by choke coil antenna by the differential signal after increasing to emission, now, shifting in this signal coverage areas
Dynamic station can carry out RTK engineering measuring point operation.There is long distance of signal transmission, be easy to the good effect of RTK precise positioning.
Brief description
Accompanying drawing part discloses this utility model specific embodiment, wherein,
Fig. 1 is fundamental diagram of the present utility model.
Specific embodiment
As shown in figure 1, Ocean Surveying signal long distance transmitter provided by the utility model, including outdoor chokes
The plug-in radio station 2 of circle antenna 1 and interior, GNSS reference receiver 3, by cable 4 respectively by GNSS reference receiver
GNSS ANT serial ports and choke coil antenna port and GNSS reference receiver DL/PW1 serial ports and plug-in radio station D number
Couple together according to port, unidirectional current 5 is accessed in described GNSS reference receiver and plug-in radio station.Preferably, described
GNSS reference receiver is VNET6 type receiver.
By choke coil antenna, GNSS reference receiver, receive domestic satellite-signal, and connect through GNSS base station
The data calculation function of receipts machine, the satellite-signal receiving is processed into differential signal 6, because of the strength of differential signal that obtains relatively
Weak, need to pass through high-power plug-in radio station, increase the intensity of differential signal, then by choke coil antenna by the differential signal after increase
To emission, now, the movement station 7 in this signal coverage areas can carry out RTK engineering measuring point operation.This device achieves
Do not have signal cover marine site in remote signal transmission, there is long distance of signal transmission, be easy to RTK precise positioning, from
And be conducive to the good effect of marine measuring point positioning.
