Sentence examples for orbital altitude from inspiring English sources
First the effect of LEO satellite with different orbital altitude and inclination on GPS orbits is analyzed under three ground station networks.
This is an experiment that takes place at a certain orbital altitude in a spacecraft in orbit around Earth, where the acceleration due to the central field is corrected for the oblateness and also the rotation of the Earth.
The extreme ultraviolet spectroscope EXtrem ultraviolet spetrosCope for ExosphEric Dynamics EXCEEDD) on board the SPRINT-A mission will be launched in the summer of 2013 by the new Japanese solid propulsion rocket Epsilon as its first attempt, and it will orbit around the Earth with an orbital altitude of around 1000 km.
As the spacecraft's orbit inclination was only about 30° and the orbital altitude was below 600 km, many high-accuracy ground-based sensors cannot observe or track these objects simply because they never appear above their horizon.
The SELENE lunar orbiter has a lower altitude (100 km) and is thus more sensitive to gravity perturbations, which may account for a less accurate orbit determination compared to that of the Chang'E-1 orbiter, which has a higher (200 km) mean orbital altitude.
We analyze how a 180° separation in the Right Ascension of the Ascending Node (RAAN) between two CubeSats (SatA and SatB) starting in the same orbit can be achieved by modifying one of the spacecraft's orbital altitude, resulting in a difference in their rate of nodal precession (defined as the drift rate) due to the J2 effect, and therefore a difference in their relative RAAN.
Beidou is the regional satellite navigation system in China, consisting of three kinds of orbiting satellites, MEO, GEO and IGSO, with the orbital altitudes of 21500 36000 km.
As the ability to lift larger weights to orbital altitudes increases, the capabilities of the sensors will improve.
The most critical region is found at orbital altitudes near 800 km with high declinations.
Scientists said the detailed studies from both high and low orbital altitudes should help determine the relationships among different layers of the atmosphere and between the atmosphere and the surface.
The acceptable level test results provide good confidence toward robust space-to-earth transmission in variable solar weather at low earth orbital altitudes.
