COLUMNS FORMAT DESCRIPTION DEFAULT VALUE & UNITS
1-6 A6 DSTATE - Requests estimation of
an instantaneous state difference at
a specific time. This capability is
extremely useful with thrusts
7 I1 Dstate Component
1 = x
2 = y
3 = z
.
4 = x
.
5 = y
.
6 = z
8 I1 Coordinate system of input indicator
=1 Inertial TOR coordinate system
=2 Position and velocity are in the
satellite along track, cross track
and radial directions.
18-24 I7 Satellite ID. 0
25-44 D20.8 Dstate value 0.0
45-59 D15.3 Dstate time (YYMMDDHHMMSS.SS)
60-72 D13.1 Dstate sigma 1.D-25
NOTE 1: The DSTATE option requires that all the data from one satellite
should be input together and in advanced time order. Also all
the satellites must be in the same order as on the SATPAR input
cards.
Not all 6 components of the DSTATE at a specific time must be
present if the user does not wish to solve for them, however
GEODYN will use a tight sigma for those components that are
not present in the estimation process
