Assuming that self-adaption control system is used for
stationkeeping of a constellation.
In a series of tweets, the mission management team said the bullet had been fired and the spacecraft was heading back to its
stationkeeping position, 12.4 miles above the asteroid.
Once separated from the launch vehicle, the 18 thrusters on the GEO Flight 3 satellite provide
stationkeeping, three-axis control and de-spinning of the reaction wheels throughout the mission.
[Stationkeeping] if S1-S2 (i) break to maintain position within a 10 x 10 m box around S2 and velocity lower than 10 cm/s (three axes) if S2-S3 (i) break to maintain position within a 5 x 5m box around S3 and velocity lower than 5 cm/s (three axes) when
Stationkeeping is reached goto [ZEM/ZEV Guidance] End.
The effect of orbital perturbations and
stationkeeping on geosynchronous orbit has been discussed in [3].
A real-time vision-based
stationkeeping system for underwater robotics applications, Proceedings of the MTS/IEEE Conference on OCEANS, Vol.
(19) This number is based on a
stationkeeping multiplier of 4.4 for Norfolk-based DDG-51s deploying to the European Command's area of responsibility on seven-month deployments.
SS/L's satellites are designed to achieve long useful orbital life through use of bipropellant propulsion and momentum-bias systems for excellent
stationkeeping and orbital stability.
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.
