MIR track prediction for INTMINS campaign APRIL98

The predicted MIR's ground tracks, which pass near INSPIRE net, are available in this home page.
The track consists from magnetic footprints calculated by magnetic mapping from MIR positions with 30 s step.
This tracks are precalculated on the base of the orbital elements detrmined by the KIAM RAN Ballistic center.

During INTMINS operations scheduling this calculations are taken into account by PIs in parallel with its own MIR track predictions based on the MIR's TLE elements. See the operations schedule ftp://nssdc.gsfc.nasa.gov/multidis/inspire/intmins/April98ops

The cojugations criteria

To find the magnetic cojugations the calculations as follows are used:

Track file parameters

For each selected time the parameters as follows are shown:

Date : - YYYYMMDD
Universal time: - hhmnss
Satellite altitude (above reference ellipsoid), km - Hs
Geographical longitude and latitude of the satellite, deg - GLONS, GLATS
Geographical longitude and latitude of the footprint, deg - GLONF, GLATF
Magnetic field line length (earth radii), Re - arcln
Angular distance between footprint and SP, deg - angdst
Selected place (SP) number and country code - #-CC
The selected place name - place

The used state vector

The calculations was done on the base of the orbital elements, determined by the Ballistic center of the KIAM RAN Keldysh Institute of Applied Mathematics Russian Academy of Sciences The last predictions was done on the base of the following state vector (shown in the Greenwich rotated coordinate system)
Epoch 19980415 (YYYYMMDD)
UT 051703.87 (HHMNSS.MS)
x 847.29144 km
y 6704.49285 km
z 0.00000000
vx -4.23768255 km/s
vy 0.53122598 km/s
vz 6.02709700 km/s
Balllistic coefficient 0.02828898 (CD*FM(m^2)/M(kg)*g0(m/s^2))
