bi-elliptic transfer
noun
(astronautics)
A
type
of
movement
of
a
spacecraft
from
one
orbit
to
another,
in
which
the
spacecraft
first
raises
its
apoapsis
to
an
extremely
high
altitude,
then,
at
the
new,
higher,
apoapsis,
performs
an
engine
burn
to
change
its
periapsis
to
that
of
the
desired
orbit,
and,
finally,
upon
reaching
the
new
periapsis,
performs
a
third
burn
to
lower
the
eccentricity
of
its
orbit
and
circularize
in
the
desired
orbit,
or
performs
these
steps
in
reverse
to
move
from
a
higher
to
a
lower
orbit.

(astronautics) A type of movement of a spacecraft from one orbit to another, in which the spacecraft first raises its apoapsis to an extremely high altitude, then, at the new, higher, apoapsis, performs an engine burn to change its periapsis to that of the desired orbit, and, finally, upon reaching the new periapsis, performs a third burn to lower the eccentricity of its orbit and circularize in the desired orbit, or performs these steps in reverse to move from a higher to a lower orbit.
The bi-elliptic transfer is a trajectory used in space missions.
