详细描述

文件后备星历

将星历数据写入二进制文件，查询时从文件读取。使用固定窗口缓存减少磁盘 IO，适合大规模星历存储场景。

二进制文件格式: [Header: 56 bytes] magic(4B) = 0x41535445 ("ASTE") version(4B) = 1 epochInt(8B) = 历元整数部分 (JD day) epochFrac(8B) = 历元小数部分 (day fraction) pointCount(8B) = 星历点数 N startTime(8B) = 首个星历点相对历元的秒数 stopTime(8B) = 末尾星历点相对历元的秒数 frameNameLen(8B) = 坐标系名称长度 [FrameName: frameNameLen bytes] (UTF-8) [Body: N × 56 bytes] time(8B) | px(8B) | py(8B) | pz(8B) | vx(8B) | vy(8B) | vz(8B) (time = 相对历元的秒数, pos = m, vel = m/s)
