Embodiment Construction
[0064] The present invention will be further described below in conjunction with the accompanying drawings.
[0065] refer to figure 1 As shown, the extreme working condition prediction method of the on-orbit temperature of the spaceborne antenna, the steps are as follows:
[0066] (1) Through the given orbital parameters of the spaceborne antenna, calculate the change law of the incident angle β angle of the sun's rays relative to the orbital surface of the spaceborne antenna within a year, as shown in Figure 2-5 shown. The parameters involved include the date of interval with the vernal equinox t, the angle of intersection ε, orbital height H, orbital inclination i, eccentricity e, and the local time of descending node t 0 , the orbital period T, the difference in right ascension of the ascending node of the orbit and the flat sun γ′, the difference in right ascension between the ascending node and the true sun α, the difference in right ascension of the true sun and the ...
