stationkeeping

stationkeeping

[′stā·shən‚keep·iŋ]
(aerospace engineering)
Keeping a satellite in geosynchronous orbit within assigned boundaries, typically within a few tenths of a degree of longitude, generally with the assistance of jet thrusters.

The miniscule thrust level is, however, sufficient for the important job of north-south stationkeeping (NSSK) in geosynchronous orbit, said John Beattie, manager of the plasma source research department at Hughes Research Laboratories in Malibu, Calif.
There are generally only three types of measurable partial losses that affect a satellite after launch: transponder failures(s); insufficient stationkeeping fuel, which results in a reduction in mission life; and insufficient power, which results in either an immediate or future quantifiable reduction in the satellite's transponder or mission life.
The satellites are designed to achieve long useful orbital life, precise stationkeeping, excellent fuel economy and orbital stability by using advanced propulsion and stabilization systems.
