Description
Technical field
The utility model relates to satellite navigation locating verification device technique field, is specifically related to a kind of low cost, portable real-time satellite navigation and positioning algorithm demo plant.
Background technology
At present, the checking of satellite navigation location algorithm is mainly through carrying out afterwards.First be data acquisition, satellite navigation location receiver receives dependent observation data and is stored in the storage medium that receiver carries with the form of binary data file, after data acquisition completes, binary data file imported personal computer and utilize software to convert thereof into general format (RINEX) file, then algorithm research personnel with afterwards or ex post simulation real-time mode general format (RINEX) file is resolved, thus the validity of verification algorithm.This process can lose some important informations in process binary data file being converted to general format (RINEX), and afterwards or in the real-time verification mode of ex post simulation, algorithm performance present the larger time delay of existence, algorithm research, tester cannot know algorithm performance immediately, and the R&D cycle extends greatly.
Therefore, be necessary to verify that the information dropout that occurs and the larger problem of time delay propose a kind of real-time satellite navigation and positioning algorithm demo plant for current satellite navigation location algorithm.Owing to carrying out the mainly individual of satellite navigation location algorithm research, therefore this device should be with low cost under the prerequisite ensureing each module quality as far as possible.
Utility model content
In order to overcome existing satellite navigation location algorithm verification mode drop-out, the deficiency of real-time verification can not be realized, the utility model proposes a kind of low cost satellite navigation location algorithm demo plant.
For achieving the above object, the technical solution adopted in the utility model is a kind of low cost real-time satellite navigation and positioning algorithm demo plant, comprise navigation antenna, GNSS navigation positioning module, pocket computer, Serial Port Line, navigation antenna is connected with navigation positioning module, and navigation positioning module and pocket computer adopt Serial Port Line to be connected.
And the binary data that described GNSS navigation positioning module exports is input to pocket computer by Serial Port Line.
And described pocket computer comprises display screen.
The beneficial effects of the utility model are, this satellite navigation location algorithm real-time verification apparatus structure is simple, easy to use, cheap, carry out the research of satellite navigation location algorithm individual can fast construction success, use this device that algorithm research personnel can be made immediately to know its algorithm performance, and carry out corresponding improvement, accelerate research and development speed; And avoid important information to lose, improve data precision, ensure to use reliably.
Accompanying drawing explanation
Fig. 1 is the structural drawing of the utility model embodiment.
Fig. 2 is the data flow figure of the utility model embodiment.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the technical solution of the utility model is described in further detail.
The utility model uses low cost GNSS navigation positioning module, navigation antenna, Serial Port Line, pocket computer.See Fig. 1, navigation antenna (101), the GNSS satellite navigation positioning module (102) of the utility model embodiment are linked in sequence with pocket computer (104), use Serial Port Line (103) to connect GNSS satellite navigation positioning module (102) and pocket computer (104).
See Fig. 2, GNSS satellite signal is received by navigation antenna and enters GNSS navigation positioning module, in GNSS navigation positioning module, export the information such as binary satellite signal to noise ratio (S/N ratio), observation data, broadcast ephemeris after the process such as gain amplification, analog to digital conversion; These information enter pocket computer by Serial Port Line.During concrete use the utility model institute generator, first navigation antenna can be accessed GNSS navigation positioning module, and use Serial Port Line to connect navigation positioning module and pocket computer; Then original observed data (the satellite signal to noise ratio (S/N ratio) of binary format, observation data and broadcast ephemeris data) is directly exported by GNSS navigation positioning module by serial ports.Run GNSS navigation and positioning algorithm in pocket computer, resolve and successfully afterwards calculation result is converted to NMEA form (satellite navigation receiver standard output form).Described pocket computer comprises display screen, directly can show positioning result, in pocket computer, such as configure correlation map software (as Google Earth, u-center etc.) can fix on map by algorithm real-time resolving fructufy markers, thus obtains algorithm performance intuitively.During concrete use the utility model institute generator, user can voluntarily as required configuration virtual serial ports to A and B, virtual serial port A is sent to after the real-time resolving results conversion of navigation and positioning algorithm is become NMEA form, the virtual serial port B that correlation map software monitors and virtual serial port A bind, then can algorithm real-time resolving fructufy markers be fixed on map, without the need to dumping to other equipment in addition.
Process, GNSS navigation and positioning algorithm, map software, the virtual serial ports such as gain amplification, analog to digital conversion are to being configured to prior art, during concrete enforcement, those skilled in the art utilize the utility model institute generator product can arrange realization voluntarily, and the utility model only provides the improvement project of hardware aspect.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
