situation analysis

Auroral Probe is one of the satellites of the INTERBALL program. This program includes two satellites Tail Probe (launched at 3 August 1995), Auroral Probe (launched at 29 August 1996), and its subsatellites.

  • About accuracy of the orbit determination and spacecraft positions calculation
  • Flight situation analysis during operations scheduling

  • Aposteriory situation analysis
Two stages of the orbital situation analysis are presented:
  • The flight stage - for using during the flight operations monthly (m) planning,
  • The afterflight aposteriory (a) stage - for using during scientific data treatment and archiving.
The satellites motion calculation during the flight situation analysis is based on the orbital elements, determined by the Ballistic center at KIAM RAN.
The modified (by backward integration) orbital elements are used during the aposteriory situation analysis. See collection of the orbital elements and the accuracy problems of the SC motion calculations.

The satellite position in the various coordinate systems and different parameters along the orbit as a function of time are shown on the plots and represented in the numerical files.

The footprints magnetic mapping and magnetic conjugations with ground based magnetic observatories and with the other related Interagency missions are shown as well. The simulative magnetic conjugations are calculated for the following groundbased magnetic observatories: EISCAT (Northern Scandinavia) and SUPER-DARN net, and for the following Interagency missions: POLAR (NASA) and GEOTAIL (NASA, ISAS).
