OEM Flashcards
what is the process of moving a satellite due to changes in the mission requirement?
Station Changing
What COE difference causes a 2X1 Ellipse in the relative motion?
eccentricity
In relation to the RSO, what will happen to the chaser satellite if it misses a burn during an R-Bar Hop?
drift away
A Drifting 2X1 in plane ellipse has a difference in which 2 COEs?
semi major axis and eccentricity
For a combined plane change, when is the 2nd Hohman transfer conducted?
apogee of the transfer orbit
During a plane-matching rendezvous when would this maneuver use the lease amount of fuel?
apogee of the transfer orbit
what two variables must be known to complete a rendezvous?
time and burn
Perch is when all COEs match except?
true anomaly
Two satellites are in the same orbit with different true anomalies.
What is it called when the chaser rendezvous with the RSO?
Co-orbital
This RPO technique creates additional waypoint around an RSO to better approximate a circle.
(FMC) Forced motion circumnavigation
When launching a satellite into a _______orbit place -matching rendezvous is always required.
Geo Stationary
Which 2 COEs will change durning a cross-track maneuver?
inclination, RAAN
Name the 2 COE’s two satellites must have in order to preform a co-planner rendezvous.
inclination, RAAN
What maneuver is conducted to preform a co-planner rendezvous?
Hohmann transfer
A satellite with an inclination or RAAN difference will oscillate in which direction.
cross-track
What does a phasing orbit alter?
the angular distance between two satilites
What difference in COE causes a permanent in-track drift?
semi major axis
How long is the time of flight for a v-bar hop?
half the RSO’s period
Which ric direction must a satellite maneuver in order to change semi-major axis?
in-track
What maneuver changes a satellite inclination or RAAN without Semi-major axis or eccentricity?
simple plane change
In what direction will a co-orbital chaser maneuver if it is behind the RSO?
negative in track
