WebApr 10, 2024 · This safety mechanism is mainly through orbit design and prediction. In the design phase, the distance between any two satellites must be greater than the minimum safe distance (MSD). For this optimization goal, some design item in Table 3 are iterated and simulated by commercial software STK. RAAN means the right ascension of the … WebDefinition. An ephemeris is a tabulation of computed positions and velocities (and/or various derived quantities such as right ascension and declination) of an orbiting body at specific times. The plural form of ephemeris is ephemerides.
