Description
Technical field
The present invention relates to satellite technology field, more particularly to a kind of magic square satellite.
Background technology
Since nineteen fifty-seven, first artificial satellite was sent into space by the Soviet Union, aerospace industry after the development of whole 60 years,
Thousands of satellites subsequently enter space, to communicate, navigating, remote sensing, the development in the field such as meteorology bring subversive change
Leather.But these satellites similarly bring the problem of unprecedented and chosen while great convenience is brought to human lives
War.
As number of satellite in orbit is growing and increased, the quantity of extraterrestrial target of mankind's space operation
It is increasingly huge, also cause space environment to become more complicated.Around the earth flight extraterrestrial target show quantity it is more, distribution extensively
The characteristics of.It is tens of thousands of away from the earth that the distribution of these extraterrestrial targets from liftoff ball only has the Low Earth Orbit of hundreds of kilometer to extend to
The geostationary orbit of kilometer.The change of the variation tendency and extraterrestrial target total quantity of nearly 60 years different types extraterrestrial target quantity
Trend.The general trend of sustainable growth is generally showed, is not only as the growth year by year of number of satellite, in addition to space mesh
The reasons such as the mutual collision between target self-decomposition and extraterrestrial target.
The increasingly complexity of space environment, the normal solar-system operation of the mankind is not only had a strong impact on, also greatly threatened
The safety of satellite in orbit.On 2 10th, 2009, the U.S. " satellite of iridium 33 " and Russia " satellite of universe 2251 " touches
Hit, this is satellite accidents first in history.According to the U.S side, this satellite collision once detected about generates thousands of
Space debris, these chip distributions are in 500 kilometers to 1300 kilometers of space, to the peace of all satellites in this altitude range
All bring great threat.
In addition to above-mentioned great space safety accident, other different security incidents of the big and small order of severity be even more without when without
Quarter is not occurring, and how to ensure that the problem of national space resources is safe becomes ever more important.Threatened to tackle space, avoid sky
Between accident, it is necessary to the Space Target Surveillance system for setting up complete set carries out detection Tracking Recognition to extraterrestrial target, obtains mesh
Target orbit parameter, contour structures, using characteristic informations such as function, optical infrared Radar Objective Characteristics, or even obtain these targets
Information is attempted in the mission planning and action of the owner, predicts the potential danger that may occur.It is this extraterrestrial target is detected,
The behavior for identifying and obtaining characteristic information is exactly space situation awareness (Space Situation Awareness).Utilization space
Situation Awareness, the satellite of this country in orbit can be effectively protected, the satellite of other countries can be carried out again tight
Close monitoring, it is to ensure that space safety is stable, obtains the foundation stone of space advantage.
Space Target Surveillance system is divided into space-based monitoring system and the major class of ground monitoring system two, the extraterrestrial target prison in the U.S.
View (SSN) is the most strong ground Space Target Surveillance system of current observing capacity, can trace back to nineteen fifty-seven earliest.The Soviet Union is at this
During year first artificial satellite of transmitting, the U.S. just starts with target range theodolite to be tracked detection to extraterrestrial target.At present
The U.S. relies on ground-based radar detection system and Photodetection system, realizes the Detection And Tracking to extraterrestrial target substantially, wherein
Radar-probing system is main force's detector of middle low orbit target acquisition, such as air force's space surveillance system (SSS) in deployment in 1961
(AFSSS) and in the Eglin radar (Eglin Radar) disposed in 1969.And on the ground of early deployment the 1980s
Base photoelectricity deep space monitoring system (GEODSS) and 2011 deployment Space Surveillance Telescope (SST) be then to high rail space
The main force member that target is detected, the acquisition available for high rail target orbit determination and characteristic information.But ground monitoring system
There is its natural limitation：
1) single earth station to extraterrestrial target especially in low rail target observation segmental arc it is shorter, to reach higher orbit determination essence
Degree then needs that number is more, the support of widespread earth station, that is, establishes the tracking and command network of distribution on global, cost is of a relatively high.
2) ground installation in observation process easily by atmospheric propagation shake, astronomical refraction, ionization flicker etc. factor shadow
Ring.In addition, the limitation of the condition such as earth curvature, sky brightness, weather so that ground monitoring system can not accomplish whole day
When, round-the-clock monitoring.
3) due to being limited to detection range, ground based observa tion is also exactly in the presence of a weak point can not be to the space mesh of high rail
Mark implements effectively observation.
The defects of in order to make up ground monitoring system, in the last few years, the U.S., are continuing to improve and develop ground based detection system
While, started the construction to space-based monitoring system, transmitted respectively at 2003 and 2005 SDI XSS-10,
XSS-11, demonstrate the ability that low rail extraterrestrial target is approached, is diversion, closely observed.The U.S. transmits after this
ANGELS satellites, geostationary orbit target can be completed approach, be diversion and observation mission.It may be said that space-based monitoring system is
It is the necessary component for strengthening space situational awareness capabilities as the important step in whole Space Target Surveillance system.My god
Although base monitoring system compensate for the defects of ground monitoring system to a certain extent, due to the development of current space-based monitoring system
The starting stage is still in, so there are still in place of some shortcomings for current space-based surveillance satellite：
1) single space-based surveillance satellite can not observe the extraterrestrial target in multiple orientation simultaneously.The space-based monitoring of Most current is defended
Star follows the design concept of traditional earth observation satellite, and observation load mounting surface is single, and sensing is relatively fixed, and the side of load
Swinging is limited.When the relative position of different extraterrestrial target and satellite differs greatly, single satellite can not be simultaneously effectively simultaneous
Care for the observation mission of multiple extraterrestrial targets.
2) do not possess the ability traced and monitored for a long time to close-in target.It is relative with extraterrestrial target in space-based surveillance satellite
When closer to the distance, satellite entirety attitude stabilization and camera side-sway is limited, observation segmental arc of the satellite that can be provided to target is shorter.
And relative distance closely causes both larger with respect to angular speed, so observation time is also very limited, fine must can not meet to track
The demand of monitoring.If carrying out the motor-driven long-time tracking observation to realize to target to whole star posture, not only controllable velocity it is slow and
And cost is high.
3) payload influences the Years Of Service of satellite for a long time in the complicated space environment of electromagnetic environment.Currently
The payload that space-based surveillance satellite carries, often in the long-term exposed space environment complicated in electromagnetic environment, load easily by
To space charged particle and the influence of electromagnetic radiation, the working time of load and the useful life of satellite are then influenceed.
With the transmitting successively of big-dipper satellite, high score series of satellites, wind and cloud series of satellites, the activity of China in space
Become increasingly frequently, but China does not possess the ability that continuous multidimensional observation is carried out to extraterrestrial target still, more lacks complete set
Space-based monitoring system.
