A TRAJECTORY ANALYSIS PROGRAM (TRAP)

Abstract

A FORTRAN IV program package has been written for the generation, analysis, and estimation of re-entry trajectories. The following functions may be performed by the program: (1) Generation of simulated noiseless trajectory data by integrating the differential equations of motion, using a predictor- corrector method. (2) Error analyses on trajectories generated by the program, in which the effects of hypothetical errors in the initial state and subsequent measurements may be studied. (3) Estimation of state vector quantities, using a recursive Kalmanfilter scheme, from (a) Simulated noisy data generated by the program. (b) Noisy radar measurements, supplied externally to the program.
