All components on the tangent plane

S2016-107-1
Propagation of the solutions
We use all orbits from 1,2 and 3 sigma issued from Genetical algorithm, and we see where the satellite is for the occultation date. North on top, and East on right.
  • Center at coordinates 0,0 is Primary
  • Black dots show the orbit with the best solution at the date of occultation
  • Green zone show orbits covering 1-sigma error
  • Blue zone for 2-sigma
  • Red zone for 3-sigma

S2001-107-1

S2001-107-1
This figure represent 194736 orbits computed to the occultation date. Each orbit is classify throw its performance, given an accuracy in kilometer :
  • 1-σ error = 73 km
  • 2-σ error = 77 km
  • 3-σ error = 85 km

S2016-107-1

S2016-107-1
This figure represent 194736 orbits computed to the occultation date. Each orbit is classify throw its performance, given an accuracy in kilometer :
  • 1-σ error = 935 km
  • 2-σ error = 935 km
  • 3-σ error = 1071 km
