The content of the invention
The purpose of the present invention is to propose to a kind of lunar base addressing scheme based on moon base earth observation optics coverage, energy
It is enough when moonscape carries out base addressing, realize the optimization of optics coverage over the ground.To achieve these goals, the present invention
The technical scheme of use is as follows：
Whole techniqueflow is broadly divided into three steps, first to the DE series almanac datas of U.S. jet propulsion laboratory
Processed, obtained real-time day ground moon positional information, and using the conversion of dependent coordinate system, further obtain same reference
Ground day, the position moon and attitude information under system；A moon base earth observation geometrical model is then set up, corresponding geometric properties are obtained；So

Brief description of the drawings
Fig. 1 is a month base earth observation geometrical model.
Specific embodiment
DE series almanac datas are obtained from American Space General Administration jet propulsion laboratory first, nutating and libration is taken into account
Influence, Selection utilization DE430 calculated as initial data (W.M.Folkner, J.G.Williams, D.H.Boggs,
R.S.Park,and P.Kuchynka,The Planetary and Lunar Ephemerides DE430and DE431,
vol.196.2014).Main data handling procedure is as follows：(1) ephemeris header file and data file are read first, by ASCII
Binary file is converted into BIN files, while checking every piece of number of days, and the time discontinuity between upper and lower block is entered
Row verification, repeatable block should be ignored, and finally according to time sequencing successively by each data block write-in BIN files, be synchronously written number
According to header file；(2) JPL ephemeris uses scholar and omits the time, according to the time sequencing, calculates data block number, then reads data
Block, the then position of each celestial body of interpolation calculation and speed, while coordinates computed number, every time, segment number, the start position of section
And the time that unitization Chebyshev inserts, calculated using these parameters and Chebyshev's interpolation algorithm, so as to count
The planet and sun coordinate in solar system coordinate system are calculated, the wherein earth is provided with sun geocentric coordinate system, and the moon is with geocentric coordinates
System is given；(3) on the basis of second step calculates moon geocentric coordinates, libration and nutating, the earth and the moon are calculated
Solar system center-of-mass coordinate.It is terrestrial coordinates by ground month center-of-mass coordinate reduction, then the moon with sun center-of-mass coordinate as origin
Coordinate is converted to solar system barycenter by the earth's core.So it is achieved that real-time ground day, the positional information moon of acquisition.Followed by correlation
The conversion of coordinate system, including sun celestial coordinate system, earth celestial coordinate system, moon celestial coordinate system, earth agreement coordinate
Conversion between system and moon ball spindle referential, it is achieved thereby that the unification of coordinate system, and can obtain in real time
Attitude information (P.G the é rard and B.Luzum, " IERS Conventions (2010), " Bur.Int.DES of ball and the moon
POIDS Mes.SEVRES,pp.1–179,2010)。
Then set up a moon geometrical model for base earth observation, it is assumed that the earth and the moon are spheroid, as shown in Figure 1.OmIt is the moon
The observation station in ball base, i.e. moonscape.BmIt is a month heart, OeIt is the earth's core, OsIt is the sun.M1And M2It was OmWith cutting for earth section
Point, they characterize a moon bounds for base earth observation.And S1With S2It is side that the sun illuminates earth scope and the earth section
Boundary's intersection point, L is OmWith OeThe intersection point of line and earth section, it is also the substar of lunar observation point.So earth surface is by too
Positive illuminated area can observe the common factor in region, that is, figure top shadow region with the moon, be only actual base last month earth observation
The region that can really observe.
It is different from traditional spaceborne airborne sensor because moon base earth observation yardstick is larger, therefore moon base pair is defined here
The optics coverage of ground observation is the ratio that the effective overlay area that can observe accounts for hemisphere surface product.Also, moon base is seen over the ground
Survey visual angle smaller, approximate consideration is done here, it is believed that moon base earth observation is observed for hemisphere, and the earth surface for shining upon
It is a hemisphere, then the overlay area that can effectively observe is then for two overlapping regions of hemisphere (do simplification to examine here
Consider, ignore solar eclipse influence).In order to characterize two normal directions of hemisphere, that is, moonscape observation station and the earth's core and too
The positive centre of sphere and the line direction in the earth's core, are changed using almanac data and coordinate system, can be obtained under same coordinate system (with the earth
As a example by celestial coordinate system) the coordinate O of menology observation stationm(x1,y1,z1) and sun sphere centre coordinate Os(x2,y2,z2), then two methods
Line direction is：
Recycling the cosine law, the angle theta between this two normals can obtain：
C=x1x2+y1y2+z1z2
θ=arccos (c/a/b)
The optics coverage of so moon base earth observation can be calculated：
C=(180- θ)/180
However, when lunar base i.e. when being closely located to the far-side of the moon of moonscape observation station, being seen to the earth sometimes
Survey occurs situation about being blocked, and we further analyze the optics coverage of the addressing to moon base earth observation of lunar base
Influence.Obviously, from from the point of view of optics over the ground, it is clear that the back side of the moon is not within consideration category, therefore we will select
Candidate's scope of location is first locked near side of the moon.Can be obtained from the geometrical relationship of Fig. 1, as ∠ BmOmM1With ∠ BmOmM2It is more than
At 90 °, the observation station of moonscape cannot observe the nearly lunar surface (not considering solar irradiation) of the whole earth.Simultaneously as the moon
The angle of visual field of base earth observation is very small, in order to convenience of calculation is made to simplify consideration, ignores the part earth and is blocked what cannot be observed
Situation, not good observation is considered as by this situation, and note coverage is 0.In order to more comprehensively embody the shadow of lunar base addressing
Ring, be interval with 1 ° of longitude and latitude and 1 day, the optics coverage to each position of near side of the moon is calculated, and obtained each
The average value of point.Because the difference between each time is little, therefore select to be calculated as a example by 2015 here.Then again
Row interpolation is entered to result of calculation, the retrievable entirety of earth observation in 2015 coverage of moonscape diverse location can be obtained and put down
Average.As can be seen from the results, it is clear that the central area of near side of the moon can obtain highest coverage, and in certain model
In enclosing, coverage difference very little is all substantially 0.49, and subsequent coverage is obviously reduced with the increase of longitude and latitude.Especially
It is the area more than 73 ° for some longitudes or latitude, and obtainable coverage starts to be decreased obviously.And longitude and latitude is simultaneously big
In 84 ° of area, the sight line of earth observation was always blocked for some time in 1 year, and coverage and central area difference are bright
Aobvious, average value is both less than 0.41.
Therefore according to our experimental result, when optics earth observation is considered, the addressing of lunar base is not suitable for being placed on
The far-side of the moon, near side of the moon is a good addressing.In addition to a certain extent for, the center of near side of the moon, i.e.,
The less region of longitude and latitude is adapted to the addressing of lunar base.The marginal position of near side of the moon, especially longitude and latitude are simultaneously greater than 84 °
Area, the coverage of earth observation can reduce substantially, it is not recommended that deployment lunar base.And other regions of near side of the moon, can
To combine other demands, consider, it may have the potentiality of certain lunar base addressing.
