纯引力轨道飞行器在精密导航、重力场测量以及基础科学研究等方面具有重要意义,辐射计效应是纯引力轨道验证质量的重要干扰力之一.针对内编队重力场测量系统,利用解析和数值计算相结合的方法,分析了内卫星辐射计效应与内编队系统参数的关系,并给出了适宜于工程计算的内卫星辐射计效应近似函数及其修正因子.分析可知,内卫星辐射计效应与腔体平均压力成正比,与腔体平均温度成反比;随腔体温差的增加而增加,随外卫星腔体半径的增加存在极小值,并且取极小值时外卫星腔体半径和内卫星半径比为常数1.189 4,这一常数是由内外卫星的球形腔体构型决定的,与腔体内温度和压力无关.当内外卫星半径比大于10时,可认为外卫星腔体充分大,此时内卫星辐射计效应与内卫星半径的平方近似成正比,随外卫星腔体半径的变化可忽略.
The pure gravitational orbiter is of great significance in precision navigation, gravitational field measurement and basic scientific research, and the radiometer effect is one of the important disturbances in the pure gravitation orbit verification quality.According to the internal formation gravitational field measurement system, the analytical and numerical calculation The relationship between the internal satellite radiometer effect and the parameters of the internal formation system is analyzed and the approximate function of the internal satellite radiometer effect and its correction factor suitable for engineering calculation are given.It can be seen from the analysis that the internal satellite radiometer effect and The average pressure of the cavity is proportional to the average temperature of the cavity, inversely proportional to the average temperature of the cavity, and increases with the increase of the temperature difference of the cavity. There exists a minimum value with the increase of the radius of the external satellite cavity. The satellite radius ratio is constant 1.189 4. This constant is determined by the spherical cavity configuration of the inner and outer satellites and is independent of the temperature and pressure in the cavity.When the radius ratio of the inner and outer satellites is greater than 10, In this case, the satellite radiometer effect is approximately proportional to the square of the radius of the internal satellite, with variations in the radius of the external satellite cavity being negligible.
