Pseudo-Stochastic Orbit Modeling Techniques for Low-Earth Orbiters [PDF]
Journal of Geodesy, 2006 The Earth’s non-spherical mass distribution and atmospheric drag cause the strongest perturbations on very low-Earth orbiting satellites (LEOs). Models of gravitational and non-gravitational accelerations are utilized in dynamic precise orbit determination (POD) with GPS data, but it is also possible to derive LEO positions based on GPS precise point ...

Low Earth Orbit Satellite Systems
Journal of Telecommunications and the Digital Economy, 2022 Satellites have been around for many decades, yet the low Earth orbit (LEO) was avoided as the cost exceeded the demand until recently. This paper is based on a live presentation to the Australian Telecommunications Association (TelSoc) by Ruth Pritchard-Kelly, Senior Advisor on Regulatory Affairs for OneWeb, and was chaired by TelSoc Broadband Futures

GPS-SBAS-Based Orbit Determination for Low Earth Orbiting Satellites
International Journal of Aerospace Engineering, 2023 A space-based augmentation system (SBAS) provides real-time GNSS correction signals via geostationary satellites for near-ground GNSS users. To use the SBAS correction for low Earth orbit (LEO) satellites, the correction, especially the ionosphere ...

Microlensing planet detection via geosynchronous and low Earth orbit satellites [PDF]
, 2015 Planet detection through microlensing is usually limited by a well-known degeneracy in the Einstein timescale $t_E$, which prevents mass and distance of the lens to be univocally determined.

Asteroid resource map for near-Earth space [PDF]
, 2011 Most future concepts for the exploration and exploitation of space require a large initial mass in low Earth orbit. Delivering this required mass from the Earth’s surface increases cost due to the large energy input necessary to move mass out of the ...
