The phrase "apogee perigee" is correct and usable in written English.
It is typically used in the context of astronomy to refer to the highest and lowest points in an object's orbit around a celestial body.
Example: "The satellite reached its apogee before descending to its perigee for a closer observation of the Earth."
Alternatives: "highest point and lowest point" or "farthest and closest point".
The guidance algorithm targets apogee, perigee, inclination and right ascension of ascending node.
During this stage, the apogee (perigee) of three satellites, namely, THA, THD, and THE, was approximately 12 R E (1.5 R E) and was located on the dusk (dawn)side of the magnetosphere.

Another version of the model, suitable for the Moon, had the direction of the line from apogee to perigee gradually shift.
The two satellites of KuaFu-B are in the same polar orbit with apogee 7.0RE, perigee 1.8RE.
Finally, the simulation results at apogee and perigee prove the correction of the slant range model and imaging algorithm.
The Moon isn't always at apogee or perigee during specific phases, either.
We usually obtain about six spectrograms between the apogee and perigee per day.

The spacecraft attained an orbit with an apogee and perigee altitude of approximately 32,000 and 400 km, respectively.
Because the Moon is roughly spherical, this corresponds to a difference of up to 30% in brightness between an apogee and perigee full Moon.
