Spacecraft beta angle
Web21. sep 2015 · The values in each lookup table are calculated from a flight data set of beta angle, orbit angle, and detector temperature every 15 seconds, discarding periods in which the spacecraft was performing special maneuvers or recovering thermally from such maneuvers. for example, the look-up table used for 2010, 2011, and part of 2012 was … WebAs can be expected, the overall temperature of the spacecraft becomes higher as the beta angle increases. The satellite spends less time in eclipse at higher beta angles, so heating …

WebThe longitude of the ascending node (☊ or Ω) is one of the orbital elements used to specify the orbit of an object in space. It is the angle from a specified reference direction, called the origin of longitude, to the direction of the ascending node, as measured in a specified reference plane. [1]
