Step one, system identification large angle maneuver high-resolution microwave remote sensing satellite has satellites in technical merit compared with other
Difference, it is determined that wanting key problems-solving；
Step 2, according to the specific requirement of large angle maneuver, it is determined that the axis of rolling around satellite carries out motor-driven scheme；
Step 3, the Sensitive Apparatus investigative range being fixed on star brought for large angle maneuver is with satellite is motor-driven and changes
Feature, invents a kind of sensor blinding analysis method based on the digital ball in space, satellite and too when each side view work
The mode of the geometrical relationship utilization space geometry of sphere cutting of sunlight is rejected, and forms a star sensor available fields, then will be each
Available fields combination under maneuvering condition, it is exactly the star sensor available fields that can be used under many attitude that it, which occurs simultaneously, at this
Layout of the star sensor on star is determined in orientation again；
Step 4, the navigation antenna for determining rail precision is improved as High Resolution Remote Sensing Satellites, in the feelings of satellite large angle maneuver
, it is necessary to which inventing a kind of suitable bilateral regards the method that work remote sensing satellite navigation antenna is laid out under condition, work is regarded for satellite bilateral
Residence time, selection for a long time stop right side regard work as main attitude, will originally should be arranged in left and right sides regard satellite
The navigation antenna of operating attitude intermediateness to the right side-looking direction biasing certain angle, make right side regard state under measurement performance more
Excellent, the left side stopped temporarily under state depending on can also take into account, to meet the measure rail precision under different flight attitudes；
Step 5, satellite is during large angle maneuver, and the light conditions of solar battery array can change, from energy balance
Angle is, it is necessary to invent energy discretionary security method for designing on a kind of star, and the light conditions to sun battle array are designed under a protection
Limit, when satellite is in illumination period and illumination angle is less than the thresholding, judges that the attitude of satellite is abnormal, takes closing institute in need on star
The tasks of a large amount of consumption energy, heater, as much as possible save energy resource consumption, are to take emergency processing to stop after ground-level finding
Response time；
Step 6, large angle maneuver needs each organic cooperation of subsystem on star to cooperate, it is necessary to invent a kind of efficient remote sensing
Being calculated on satellite multisystem task cooperation integrated control method, being proposed according to user for task, star needs which point is
System participates in work, according to the mode of task, time, independently calculates the internal cohesion sequential that each subsystem cooperates, according to
The task chain of generation is performed in order, and script is needed into the troublesome operation of user on foreground step by step, is converted on the star of backstage and is calculated
Machine is from host computer and control；
Step 7, required precision of the high-resolution imaging satellite to the time is higher, it is necessary to which the equipment to each use time on star is built
A unified accurate benchmark is found, high-precision calibration method during a kind of pulse per second (PPS) school based on global positioning system is invented, will
All time users directly receive the pulse signal of GPS units output per second on star, realize time high unity；
Step 8, High Resolution Remote Sensing Satellites are big to the demand of electric energy, and high current can produce larger electromagnetic field through celestial body, no
Magnetic is only reduced as far as possible by design away from but also inventing a kind of radar satellite remanent magnetism based on high current away from test side
Method, high current is delivered to the front end disconnection that loaded antennas carries out wireless transmission on star, is returned electric current using load absorption device
Receive, be maintained to flow through on star electric current inside cable it is true while, it is to avoid the body wound that wireless transmission is caused to tester
Evil；
Step 9, high-resolution imaging proposes high requirement to the beam-pointing accuracy of satellite, and sensor is accurately obtained in development
Installation situation, also data precision is improved by the selection of measuring basis, invent a kind of precision measure reference design method,
The primary standard mirror of Satellite observation is designed in the structural body of loaded antennas, it is all in master to obtain all precision measure data
Data under reference mirror coordinate system；Meanwhile, load also builds the sensing of electric wave beam with primary standard mirror when carrying out electric performance test
Direct relation is found, the optical axis of electric axis and prism is set up into direct correlation, transmission link is reduced, beam-pointing accuracy is improved；
Step 10, the broader bandwidth of High Resolution Remote Sensing Satellites, frequency are high, are passed with the number on star, relaying subsystem easily occurs
Radio frequency interference to broadband with the satellite Electro Magnetic Compatibility of frequency range multi-load, it is necessary to be designed, and number is passed into antenna first utilizes exhibition
Antenna is stretched out celestial body by opening mechanism, and the method for utilization space decay reduces signal intensity of the number biography at loaded antennas, secondly existed
Increase wave filter in the receiving channel of load, the signal that logarithm passes frequency range is suppressed, and relay antenna finally is arranged on into celestial body
Upper one end away from loaded antennas, controls the sensing of relay antenna dorsad loaded antennas, reduces influence therebetween；
Step 11, the equipment amount of high-resolution satellite is big, during vacuum thermal test it is wireless change cable status do not only exist it is larger
Operational risk, and need to take the longer development time, it is necessary to invent a kind of wireless high-power whole star vacuum thermal test of transmitting
Method avoid above mentioned problem；The device of microwave can be absorbed using a kind of, the problem of microwave leaks can not only be solved, moreover it is possible to
Make the Orbital heat flux around satellite truer, meet the purpose of experiment.
2. large angle maneuver high-resolution microwave remote sensing satellite overall control method according to claim 1, its feature exists
In, in the step one determine want key problems-solving including whole star need solution attitude maneuver, configuration of star sensor head
With installing, navigation antenna energy security method for designing, magnetic moment test and compensation when installing with layout method, high-precision school, on star,
Precision measure reference design, multisystem task cooperation integrated control method, with frequency range multi-load EMC Design, wireless big work(
Rate is launched whole star vacuum thermal test, large angle maneuver microwave satellite and constituted.
3. large angle maneuver high-resolution microwave remote sensing satellite overall control method according to claim 1, its feature exists
In the specific requirement of, the step 2 according to large angle maneuver, it is determined that the axis of rolling around satellite carries out motor-driven scheme, attitude machine
It is dynamic to provide torque by counteraction flyback.
4. large angle maneuver high-resolution microwave remote sensing satellite overall control method according to claim 1, its feature exists
In, two secondary navigation antennas are configured in the step 4, it is full in the case of satellite large angle maneuver by layout optimization design
Foot is regarded and the measure rail precision under right passing flight in left side.
5. large angle maneuver high-resolution microwave remote sensing satellite overall control method according to claim 1, its feature exists
In the step 5 Satellite is during large angle maneuver, and the light conditions change of solar battery array is violent, to prevent electric power storage
Batteries, by power supply slave computer and house keeping computer, are implemented over-pressed, under-voltage, excessively stream and protected by pond group overcharge and overdischarge
Shield measure, it is ensured that the energy safety of supply.
