R&D Qib

(1) Chaw Taws Teeb Pom Kev Satellite

In terms of satellite R&D, in accordance with the judgment of satellite technology development trend and commercial development mode, the core technical team has broken through the traditional design concept and adopted the technical route of "satellite platform and load integration". After four times of progress in ten years, the weight of the satellite has been reduced to 20kg from 400kg of the initial generation.

At present, SpaceNavi has an annual output of more than 200 satellites, and has achieved self-developed mass production of core single machines, including magnetic torquer, magnetometer, central computer, star sensor and imaging processing box, etc., and gradually formed a whole industrial chain cluster with satellite R&D and production as the core.

(2) Kev sib txuas lus satellite

With a mature technical foundation in satellite R&D, SpaceNavi has undertaken and completed several national communication satellite R&D tasks since 2019. Currently, SpaceNavi has become a key supplier to China Satellite Network in the development of communication satellites. Now, Changguang Satellite is actively planning to establish a communication satellite production line. So far, it has initially developed an annual R&D capability of 100 communication satellites.

Tsis tas li ntawd, SpaceNavi tau ua tiav R & D ntawm satellite-rau-hauv av laser davhlau ya nyob twg, inter-satellite laser davhlau ya nyob twg thiab hauv av laser chaw nres tsheb, ua tiav tag nrho cov txheej txheem kev xeem ntawm satellite-rau-hauv av thiab inter-satellite 100Gbps laser cov ntaub ntawv xa mus, thiab tsim ib qho chaw high-ceev laser cov ntaub ntawv kis tau tus mob network xeem system.

(3) Satellite Constellation Management

SpaceNavi tau tsim ib qho kev tsis siv neeg digital satellite constellation tswj kev ua haujlwm, paub txog kev ua haujlwm satellite tsis siv neeg, kev xav tau, cov ntaub ntawv tsim tawm thiab kev faib tawm, thiab muaj peev xwm ua tau zoo ntawm kev tswj hwm telemetry thiab satellite ua haujlwm. Cov ntaub ntawv duab tshiab ntawm 10 lab square kilometers tuaj yeem tau txais txhua hnub, thiab kev ua haujlwm txhua hnub ntawm 1,700 zaug tuaj yeem ua tiav. Lub sijhawm xa tawm tsawg dua 1 feeb, cov haujlwm niaj hnub kis tau tus mob tuaj yeem yog 300 lub voj voog. Hauv ib hnub, txhua qhov chaw hauv ntiaj teb tuaj yeem tuaj xyuas 37-39 zaug hauv ib hnub, thiab SpaceNavi muaj peev xwm npog tag nrho lub ntiaj teb 6 zaug hauv ib xyoos thiab npog tag nrho Tuam Tshoj txhua ib nrab hli.

(4) Cov ntaub ntawv khoom

Relying on "Jilin-1" satellite constellation, SpaceNavi has gradually established a mature product system: The first is basic data product of 6 categories, including panchromatic data, multispectral data, nighttime light data, video data, spatial target data and DSM data; The second is thematic product of 9 categories in the fields of agriculture and forestry production, environmental monitoring and intelligent city, etc.; The third is platform product of 20 categories, including data access system, earth remote sensing emergency service system and remote sensing monitoring and supervision, etc. SpaceNavi is committed to "serving 7 billion people in the world with remote integrated space-air-ground sensing information products", and has successively provided more than 1 million high-quality remote sensing information services to users in more than 70 countries.

Cov xwm txheej ntau lawm

(1) Optical Processing Area

Tag nrho cheeb tsam ntawm qhov chaw kho qhov muag yog 10000m². Cov cheeb tsam no muaj peev xwm ua tiav cov khoom loj ntawm cov khoom siv kho qhov muag siab, thiab muaj peev xwm ua cov khoom siv kho qhov muag ua los ntawm cov iav ceramics thiab silicon carbide, thiab lwm yam los ntawm ntxhib mus rau nplua, nrog rau kev kuaj pom zoo.

(2) Lub koob yees duab sib dhos thiab qhov chaw hloov kho

The total area of the camera assembly and adjustment area is 1,800m2. Here, re-test of optical camera components before assembly and adjustment, optical assembly, commissioning and testing of camera system are conducted. This area has the capacity of small batch production of small and medium-sized optical cameras.

(3) Satellite zaum kawg Assembly Area

Tag nrho cov cheeb tsam ntawm lub satellite kawg sib dhos cheeb tsam yog 4,500m². Cov cheeb tsam no muaj peev xwm ua tau raws li qhov yuav tsum tau ua ntawm pawg zaum kawg ntawm satellites.

(4) Satellite Test Area

Tag nrho cheeb tsam ntawm qhov chaw kuaj satellite yog 560m². Ntawm no, ib qho kev sim tshuab ib zaug, kev ntsuas qhov system, tag nrho satellite duab sib xyaw ua ke kev sim thiab cov qauv davhlau sim tuaj yeem ua tiav. Qhov chaw no muaj peev xwm ntsuas ntau tshaj 10 satellites synchronously.

(5) Lub koob yees duab Radiometric Calibration Area

Thaj tsam ntawm lub koob yees duab radiometric calibration cheeb tsam yog 500m². Ntawm no, radiometric calibration cov hauj lwm ntawm aerospace lub koob yees duab thiab so thiab tshuaj ntsuam ntawm cov focal dav hlau ntes chips yuav ua tau.

(6) Environmental Test Area

Tag nrho cheeb tsam ntawm ib puag ncig kuaj yog 10,000m², Environmental tests, suav nrog kev vibration test, modal test, atmospheric thermal cycle test, vacuum thermal cycle test, thermal balance test, thermo-optical test, sound test, strain test and micro-vibration test, etc. thaum lub sij hawm tsim cov satellites thiab cov khoom yuav ua tau.
