Abstract
City CDR wireless broadcast system GNSS differential data transmission methods are based on the invention provides one kind, are comprised the following steps：Based on CORS data station output difference data；Obtain CORS data station output difference data and be transmitted by radio broadcasting in selected frequency range；GNSS receiver is attached with the radio broadcasting signal of above-mentioned selected frequency range and received the differential data of the radio broadcasting signal, GNSS receiver can realize that difference is resolved based on above-mentioned differential data, the present invention transmits GNSS differential data methods using city CDR (Chinese Digital broadcast) wireless broadcast system, customer using cost can be reduced, as long as the place of city wireless broadcast singal can be received in theory, GNSS receiver can freely use GNSS differential datas, reduce customer using cost.Because city wireless broadcast system can cover each corner of city, user job distance is so greatly increased.
Description
Technical field
The present invention relates to GNSS differential data transmission technical fields, and in particular to one kind is based on city CDR radio broadcastings system
System GNSS differential data transmission methods.
Background technology
Traditional GNSS differential data transmission modes have two kinds：One kind is based on wireless network transmissions；One kind is based on without line number
The platform that conducts electricity is transmitted.Wireless network transmissions differential data, user needs to pay wireless network data flow expense, and a user
Name synchronization can only be used in a GNSS receiver.Wireless network is transmitted using radio station, due to common data radio station work(
Rate is limited, and, in 3-10KM or so, such user job distance is limited, influences Consumer's Experience for transmission range.
The content of the invention
It is poor based on city CDR wireless broadcast systems GNSS the invention provides one kind in order to solve the defect of above-mentioned deficiency
Divided data transmission method, can reduce customer using cost, as long as the place of city wireless broadcast singal can be received in theory,
GNSS receiver can freely use GNSS differential datas, reduce customer using cost.Because city wireless broadcast system can
To cover each corner of city, user job distance is so greatly increased.
City CDR wireless broadcast system GNSS differential data transmission methods are based on the invention provides one kind, including it is following
Step：
Based on CORS data station output difference data；
Obtain CORS data station output difference data and be transmitted by radio broadcasting in selected frequency range；
GNSS receiver is attached with the radio broadcasting signal of above-mentioned selected frequency range and received the radio broadcasting
The differential data of signal；
GNSS receiver can realize that difference is resolved based on above-mentioned differential data.
Above-mentioned method, wherein, the acquisition CORS data station output difference data are simultaneously led in selected frequency range
In crossing the step of radio broadcasting is transmitted, the selected frequency range is 430-440.
Above-mentioned method, wherein, the step of the data station output difference data based on CORS in, the CORS data stations
It is any one the CORS data station in Chinese Digital broadcast.
Above-mentioned method, wherein, the selected frequency range be 430-440 in, to select frequency range in choose
By radio broadcasting be transmitted differential data by any frequency.
The present invention has advantages below：GNSS difference is transmitted using city CDR (Chinese Digital broadcast) wireless broadcast system
Data method, can reduce customer using cost, as long as can receive the place of city wireless broadcast singal in theory, GNSS connects
Receipts machine can freely use GNSS differential datas, reduce customer using cost.Because city wireless broadcast system can be covered
Each corner of city, so greatly increases user job distance.
Brief description of the drawings
By the detailed description made to non-limiting example with reference to the following drawings of reading, the present invention and its feature, outward
Shape and advantage will become more apparent upon.Identical mark indicates identical part in whole accompanying drawings.Not deliberately proportionally
Draw accompanying drawing, it is preferred that emphasis is purport of the invention is shown.
Fig. 1 is that a kind of flow based on city CDR wireless broadcast system GNSS differential data transmission methods of the invention is shown
It is intended to.
Specific embodiment
In the following description, a large amount of concrete details are given to provide more thorough understanding of the invention.So
And, it is obvious to the skilled person that the present invention can be able to without one or more of these details
Implement.In other examples, in order to avoid obscuring with the present invention, do not enter for some technical characteristics well known in the art
Row description.
In order to thoroughly understand the present invention, detailed step and detailed structure will be proposed in following description, so as to
Explaination technical scheme.Presently preferred embodiments of the present invention is described in detail as follows, but in addition to these detailed descriptions, this
Invention can also have other embodiment.
Shown in reference picture 1, city CDR wireless broadcast system GNSS differential data transmission sides are based on the invention provides one kind
Method, comprises the following steps：
Step S1：Based on CORS data station output difference data, wherein specifically including, CORS data stations are that Chinese Digital is wide
Any one CORS data station in broadcasting.
Step S2：Obtain CORS data station output difference data and carried out by radio broadcasting in selected frequency range
Transmission.Wherein, selected frequency range is 430-440, more preferably, to choosing any frequency in selected frequency range
Differential data is transmitted by radio broadcasting.
Step S3：GNSS receiver is attached with the radio broadcasting signal of above-mentioned selected frequency range and received the nothing
The differential data of line broadcast singal.
Step S4：GNSS receiver can realize that difference is resolved based on above-mentioned differential data.
The course of work of the invention is：CORS data station output difference data, are input into city CDR wireless broadcast systems,
Then a certain frequency can receive CDR frequency ranges to whole city's radio broadcasting, now each in city in 430-440
GNSS receiver can realize that difference is resolved.As long as so user, can using the GNSS receiver that can receive CDR frequency ranges
The free differential data broadcast using city CDR wireless broadcast systems.Such that it is able to realize, customer using cost can be reduced,
As long as can receive the place of city wireless broadcast singal in theory, GNSS receiver can freely use GNSS difference numbers
According to reduction customer using cost.Because city wireless broadcast system can cover each corner of city, use is so greatly increased
Family operation distance.
Presently preferred embodiments of the present invention is described above.It is to be appreciated that the invention is not limited in above-mentioned
Particular implementation, wherein the equipment and structure that do not describe in detail to the greatest extent are construed as giving reality with the common mode in this area
Apply；Any those of ordinary skill in the art, in the case where technical solution of the present invention ambit is not departed from, all using the disclosure above
Methods and techniques content make many possible variations and modification to technical solution of the present invention, or be revised as equivalent variations etc.
Effect embodiment, this has no effect on substance of the invention.Therefore, every content without departing from technical solution of the present invention, foundation
Technical spirit of the invention still falls within the present invention to any simple modification, equivalent variation and modification made for any of the above embodiments
In the range of technical scheme protection.
