% Compute the ascending node for the desired local time. The mean sun is computed using the Simon Newcomb equations which are also used in the Astronomal Almanac. The local time is just the difference between this mean sun angle and the right ascension of the ascending node. See also LTAN. -------------------------------------------------------------------------- Form: W = SunSyncNode( lt, jd ) -------------------------------------------------------------------------- ------ Inputs ------ lt (1,1) Local time, expressed in hours (0-23) jD (1,1) Julian date ------- Outputs ------- W (1,1) Right ascension of the ascending node --------------------------------------------------------------------------
