Description
Technical field
The invention mainly relates to satellite navigation receiver technical field, specifically a kind of fast quickly cooling of satellite navigation receiver is opened
Dynamic method.
Background technology
General satellite navigation receiver is when cold start-up, it is necessary to which the satellite-signal of the long period of collection, could be solved
Calculate accurate navigation results.Because, satellite navigation receiver needs first to obtain the navigation such as ephemeris when cold start-up
Relevant information could resolve navigation results, it is necessary to which complete information could be obtained by gathering the satellite-signal of long period.Generally defend
Star navigation neceiver needs the satellite-signal of collection 30 seconds or so to complete cold start-up.
Some guided missiles or guided cartridge, do not power before transmission.On the one hand, do not powered before launching and avoid abnormal ignition
It is dangerous；On the other hand, cold guided missile or guided cartridge before launching, can use thermal cell as the energy, during with storage
Between it is long, safeguard simple advantage.However, the flying speed of guided missile or guided cartridge is fast, the flight time is shorter, according to common side
Method cold start satellite navigation neceiver, it is necessary to the long period could export effective navigation data, be unfavorable for guided missile or guidance big gun
The control of bullet.
The content of the invention
To solve the deficiency of current technology, present invention combination prior art is led from practical application there is provided a kind of satellite
Navigate the quick cold start-up method of receiver, and this method causes satellite navigation receiver to provide effective navigation rapidly after powered up
As a result.
To achieve the above object, technical scheme is as follows：
The quick cold start-up method of satellite navigation receiver, comprises the following steps：
Step one：Satellite-signal is received by injector, and analyzes from satellite-signal navigation-related information；
Step 2：Missile-borne navigator no power, and injector is provided by wireless power to the memory of missile-borne navigator
Energy, and navigation-related information is write by radio communication by memory；
Step 3：After the satellite navigation receiver of missile-borne navigator is powered, satellite navigation receiver reads from memory and led
Boat relevant information；
Step 4：Satellite navigation receiver navigation relevant information, handles satellite-signal and starts navigation calculation.
Step 2 can repeatedly, and an injector can write the memory of multiple missile-borne navigators.
It can be used RFID technique that navigation-related information is write into memory in step 2.
RFID identifiers built in injector, RFID identifiers provide energy, RFID by sending electromagnetic wave for RFID tag
Label carries memory, and navigation-related information can be exchanged between RFID identifiers and RFID tag, realizes the related letter of navigation
Breath writes memory from injector.
Step 3 Satellite navigation neceiver wirelessly reads navigation-related information from memory.
Beneficial effects of the present invention：The method provided by the present invention, can be in the cold feelings of satellite navigation receiver
Navigation-related information is injected under condition, satellite navigation receiver can directly obtain navigation-related information after being powered and quickly start,
It is exportable effective navigation data in short time, is conducive to the control of guided missile or guided cartridge.
Brief description of the drawings
Accompanying drawing 1 is workflow schematic diagram of the invention；
Accompanying drawing 2 is structural representation of the embodiment of the present invention.
Embodiment
With reference to the drawings and specific embodiments, the invention will be further described.It should be understood that these embodiments are merely to illustrate
The present invention rather than limitation the scope of the present invention.In addition, it is to be understood that after the content of the invention lectured has been read, this area
Technical staff can make various changes or modifications to the present invention, and these equivalent form of values equally fall within scope defined herein.
As shown in Figure 1, it is the workflow diagram of the present invention, the quick cold start-up method of satellite navigation receiver is held successively
Row is Step 1: Step 2: Step 3: step 4.
In step one：Injector first receives satellite-signal, and analyzes from satellite-signal navigation-related information；Navigation
Relevant information includes satellite orbit parameter, current position, current time etc..
In step 2：Missile-borne navigator no power, and injector by memory from wireless power to missile-borne navigator
Energy is provided, the energy work that memory can be provided using wireless power, injector is simultaneously related navigation by radio communication
Information write-in memory.
In this step, RFID (radio-frequency technique) can be used to complete, RFID identifiers can send electromagnetic wave, be RFID marks
Label provide energy.RFID tag carries memory function.Navigation-related information can be between RFID identifiers and RFID tag
Exchange, realize that navigation-related information writes memory from injector.
Injector can only give a memory write information, can also be believed with an injector to multiple memory writes
Breath.Such a injector can just help the satellite navigation receiver of multiple missile-borne navigators to realize quick startup, step 2
Can be repeatedly.
In step 3, after the satellite navigation receiver of missile-borne navigator is powered, satellite navigation receiver is read from memory
Navigation-related information.So satellite navigation receiver just immediately obtained such as satellite orbit parameter, current position, it is current when
Between etc. navigation-related information, it is no longer necessary to receive satellite-signal for a long time to obtain these information.
In step 4, satellite navigation receiver can utilize the navigation-related information obtained in step 3, quick to start, short
The effective navigation data of output in time.
Embodiment：
As shown in Figure 2, injector 10 includes injector loop aerial 11 and injector satellite navigation receiver 12, bullet
Carry navigator 20 and include missile-borne navigator loop aerial 21, missile-borne navigator DVB 22 and memory 23, in step
In one, injector satellite navigation receiver 12 receives the signal that aeronautical satellite 30 is sent first, and calculates navigation-related information,
Injector 10 passes through the transceiving electromagnetic ripple of injector loop aerial 11；
In step 2, the electromagnetic wave that injector loop aerial 11 is sent has two effects, on the one hand, electromagnetic wave can be by
Missile-borne navigator loop aerial 21 absorbs, for the energy needed for memory 23 provides work, and on the other hand, navigation-related information leads to
Electromagnetic wave transmission is crossed, memory 23 is written into；
In step 3, after missile-borne navigator 20 is powered, missile-borne navigator DVB 22 is read from memory 23 leads
Boat relevant information；
In step 4, missile-borne navigator DVB 22 receives the signal of aeronautical satellite 30, and using being obtained in step 3
The navigation-related information obtained quickly starts, and exports effective navigation results.
