4 the determination of lunar gravity field technical requirements of the lunar exploration program and evaluation of 
is determined by the ground tracking lunar satellite observations of deep space network capacity and the following factors of lunar gravity field: the lunar satellite orbit altitude and inclination; the running time of the lunar satellite tracking arc length and lunar satellite; the ground of deep space network tracking lunar satellite sampling rate; the ground of deep space network tracking accuracy.The following combination of Chang'e-1 circular polar orbit satellite are analyzed.4.1 circular polar orbit lunar satellite, the height and the inclination of
in the study of lunar gravity field, because of the sensitive degree of different orbital inclination of satellite gravity field coefficients are different, so usually require emitting a plurality of different angle rings and lunar satellite can obtain more comprehensive lunar gravity field information, only a the moon is very difficult to obtain the overall precision of the lunar gravity field.If only a lunar satellite, the polar circle orbit for lunar gravity field is the best choice, because it can ensure better coverage of the moon.According to the characteristics of
due to gravity with square distance attenuation, so in the detection of the gravity of the moon, lunar satellite height should be as low as possible.Now do a analogy, for 200km and 100km orbit height lunar satellite, the performance of the detection performance of lunar gravity field ring is equivalent to 734km and 367km satellite orbit height of the gravity field of the earth.With the satellite altitude, gravity disturbance acting on the satellites quickly becomes smooth, large amplitude attenuation itself.Specific see Figure 2, bottom are respectively 70km, 100km, 150km and 200km orbit height lunar gravity map, calculated using the LP165p lunar gravity field model.So for the detection of the lunar gravity field satellite, as far as possible to reduce the satellite altitude is very important.4.2 circular polar orbit lunar satellite arc length and the running time of the
if there is no tracking data far moon, only using the observational data of recent moon, so that the maximum tracking arc length can choose to disappear as an arc of satellite, lunar satellite running time is mainly to ensure the observational data of the moon has adequate coverage.In a certain data redundancy, for the calculation of 50 order gravity field goal, at least ensure uniform coverage of 440 arcs, i.e. at least ensure flight 440 times, for the height of the 200km lunar satellite, need at least 40 days running.Similarly, for the calculation of 30 order goal, at least ensure uniform coverage of 260 arcs, for the height of the 200km lunar satellite, it would take at least 24 days running.When the orbit height is reduced to 100km, due to run a lap time is shortened, the time can be shortened to obtain coverage.
