Abstract
Once the satellite is in space, it is very important to
make sure that it is in its correct and prescribe orbit, along with
the appropriate attitude, at any given point of time. Orbit
propagators are used to determine propagated position and
velocity of the satellite. Various perturbations, faced by the
satellite in the space, are also incorporated to portray the actual
picture. An on-board implementation of the orbit propagator is
desired for real time propagation of the orbit. All the algorithms
are developed for the low earth orbit (LEO) satellites. The
propagator is implemented on performance efficient and high
speed digital signal processor (DSP) TMS320C6713, a product
of Texas Instrument. The key feature of this processor, real time
data exchange (RTDX), is exploited to show our results on the
host on-board computer.
