ANSI-C program: ORB_prop.c
NAME
ORB_prop -Calculate
additional state vectors using orbit propagation and
interpolation
SYNOPSISORB_prop <PROC_par>
[nstate] [interval] [extra]
| <PROC_par> | MSP processing parameter file |
| [nstate] | number of state vectors to calculate (enter - for a value determined from the duration of the existing state vectors) |
| [interval] | time interval between state vectors (default: input state vector time interval) |
| [extra] |
extra time for state
vector coverage at start and end of image (default= 30.0
s.) |
EXAMPLE
ORB_prop p05263.slc.par - 10. 30.
DESCRIPTION
ORB_prop calculates additional state vectors given at
least one state vector in the MSP image parameter file. This
program is useful in generating state vectors that extend outside
of the image bounds that are required for geocoding applications.
New state vectors are calculated by polynomial interpolation if
there are more than 1 existing state vector. If there is only one
state vector, then the new state vectors are generated by
integration of Newton's equation of motion.
