Up to the application [J] in meteorological and atmosphere environment supervision. meteorological and environment journal, 2009,25 (05):48-56. "), sounding gas
Ball (" sounding balloon measurement air [J]. Physical Education Teacher, 1991 (Z1). "), additionally using GPS/LEO Radio Occultation skills
Art earth atmosphere is detected (" GPS/LEO Radio Occultations holographic inversion technology [D]. Shanghai University, 2012. ").Sounding
Balloon carries sonde and air is detected, but sonde is subject to the interference of environment than larger, dislikes in altitude low temperature, high temperature
Under bad environment, various kinds of sensors may fail, increase detection difficulty.Meteorological satellite, laser radar and Occultation Technique there is also
Certain defect, they obtain the parameter of air just with single signal inverting, inevitably cause detecting error
【Utility model content】
Technical problem to be solved in the utility model is to pass for earth atmosphere detection system in above-mentioned prior art
Sensor failure and the deficiency of single signal inverting, there is provided a kind of earth atmosphere detection system based on gps signal.
This utility model is employed the following technical solutions：
A kind of earth atmosphere detection system based on gps signal, the system include：Gps satellite, LEO satellite, and ground
Face control station, the LEO satellite and ground control station are included respectively for receiving the first and second of gps satellite position signalling
GPS, the outfan of first and second GPS are connected with the data processing unit of ground control station.
The outfan of the first described GPS passes through the data processing unit phase of communication system and ground control station
Even, second GPS is directly connected with the data processing unit of ground control station.
The LEO satellite further includes dynamic module, supply module and navigation control module.
Compared with prior art, this utility model at least has the advantages that：
The system overcomes existing earth atmosphere detection system sensor failure and single signal inverting and using single
The deficiency detected by detection body, receives the radio signal from gps satellite using earth station and LEO satellite, simultaneously with this
The parameter of earth atmosphere is obtained, Atmospheric Survey precision is improved, using LEO satellite, orbit altitude is low so that transmission delay is short, road
Footpath loss is little, and sending allowance is little, lightweight and small power consumption.
Ground station receiver is arranged on ground diverse location, and gps satellite and LEO satellite be not in the same time relative to earth station
Position also different, can obtain not in the same time, the terrestrial atmospheric parameters of diverse location, in order to carrying out supplementing to detection data and
Perfect, quickly can be accessed using distributed data processing, multi-user use；System design is flexible.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.

Wherein：1.GPS satellites, 2.LEO satellites, 3. earth station.
【Specific embodiment】
This utility model provides a kind of earth atmosphere detection system based on gps signal, in this detection system, ground
Stand and LEO satellite simultaneously radio signal of the reception from gps satellite, by data processing centre by this these radio signal
Contrasted, obtained the parameter of earth atmosphere.
Refer to shown in Fig. 1 to 3, the utility model discloses a kind of earth atmosphere detection system based on gps signal, institute
The system of stating includes：For sending the gps satellite containing satellite position information；For the LEO satellite detected by earth atmosphere；
The earth station of gps satellite time synchronized and Atmospheric Survey is completed for receiving LEO satellite and gps satellite signal；With for receiving
Earth station's information the communication system being transmitted；Wherein, the gps satellite is connected with LEO satellite and earth station respectively, described
Earth station is connected to the communication system；The earth station includes ground GPS receiver and data processing centre, the ground
GPS is used for completing gps signal reception and gps satellite time synchronized, and the data processing centre is used for satellite receiver
All gps signals, and the signal be analyzed obtain atmospheric parameter.
In FIG, the atmospheric sounding systems designed by this utility model have four parts constitute, i.e., gps satellite, LEO satellite,
Ground control station and communication system.Wherein, LEO satellite is mainly by power plant module, supply module, navigation control module and first
GPS is constituted；Ground control station is mainly made up of the second GPS and data processing centre.
Be equipped with the first GPS on the LEO satellite, complete gps satellite time synchronized, gps signal receive and
The function of satellite fix.Ground control station is provided with the second GPS, completes gps satellite time synchronized, and gps signal is received
Function.The gps signal that LEO satellite and ground control station are received all sends data processing centre to, by data processing centre
Coordinate to collect the two signals, and both are analyzed obtain atmospheric parameter, complete the detection to air.
In enforcement example shown in Fig. 2, first according to gps satellite ephemeris, and the first GPS meter of LEO satellite
Calculate the 2 relative position with ground control station 3 of gps satellite 1 and LEO satellite.First GPS of LEO satellite 2 is received
Signal from gps satellite 1 is S1, and the signal from gps satellite 1 that the second GPS of ground control station is received is
S2, and S2 is stored to data processing centre.Signal S1 is forwarded to LEO satellite 2 number of ground control station 3 by communication system
According to processing center.When ground control station 3 is located at diverse location, and gps satellite 1 and LEO satellite 2 relative 3 with earth station
When diverse location, the terrestrial atmospheric parameters of diverse location in the same time can be obtained not.
In data processing principle block diagram shown in Fig. 3, after data processing centre obtains signal S1 and S2, by comparing letter
Number S1 and signal S2, obtains terrestrial atmospheric parameters.
