Primary pointing vector #47

Open tpreynolds opened 6 years ago

tpreynolds commented 6 years ago

Primary pointing objective will be to the sun; secondary to UW ground station. the UW vector needs to be made time varying in target generation.

Make a function that computes the inertial vector pointing nadir at UWs lattitude and longitude based on our orbit. The function should output the constant inertial vector for which we will be pointing at UW if it is below us when we cross the lattitude line on our orbit

@bbarzgaran should have mentioned this today - but once you have the inertial vector we want, can you tack on a bit of code that will build a quaternion using the sun vector as primary, seattle/nadir as secondary? That should be our pointing objective for those times (the sun is more important for us now)
