The purpose of this optimization is to obtain a final stable circular Low Earth Orbit (LEO) with maximum height. A subset of parameterized variables are optimized by the GA in order to achieve the mission purpose while satisfying the constraints and maximizing the final height of the orbit, ...
A single LEO provides around 500 globally distributed occultations per day, and a number of LEO constellations of 6–8 satellites have been proposed. This quantity of data could be used to provide improved initial conditions for forecast runs with a process known as data assimilation. Data ...
, containing an epilithic and endolithic rock-dwelling community of cyanobacteria into low Earth orbit (LEO) at a height of approximately 300 kilometers. ... Olsson-Francis,Karen,de,... - 《Applied & Environmental Microbiology》 被引量: 55发表: 2010年 A Global Distribution of the Stratospheric...
Using GPS receivers on board low Earth orbit (LEO) satellites, this technique is able to detect the RO phase change of two L-band signals (L1 at 1575.42 MHz and L2 at 1227.60 MHz) crossing the atmosphere, transmitted by a GPS satellite. Because of the vertical variations in the ...
Optimization of Hybrid Satellite Constellations using Multiple Layers and Mixed Circular-Elliptical Orbits Previous research in satellite constellation designs has focused on Low Earth Orbit (LEO) communication systems that service a global market of uniform demand. This paper addresses the challenge of des...

The Global Navigation Satellite System radio occultation technique provides materials for the validation of a mathematical description of the topside ionosphere up to the low Earth orbit (LEO) satellite altitude. An attempt to represent the topside electron density profile is using 伪-Chapman function ...
GNSS satellites send signals through the atmosphere of the Earth, and a GNSS receiver mounted on a Low Earth Orbit (LEO) satellite receives them. Through GNSS RO, refractivity will be estimated, which is considered the main parameter in the determination of planetary boundary layer height (PBLH...
