Measuring a Low-Earth-Orbit Satellite Network
2023 IEEE 34th Annual International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC), 2023 Starlink and alike have attracted a lot of attention recently, however, the inner working of these low-earth-orbit (LEO) satellite networks is still largely unknown. This paper presents an ongoing measurement campaign focusing on Starlink, including its satellite access networks, gateway and point-of-presence structures, and backbone and Internet ...

Balanced Low Earth Satellite Orbits [PDF]
Advances in Astronomy, 2020 The present work aims at constructing an atlas of the balanced Earth satellite orbits with respect to the secular and long periodic effects of Earth oblateness with the harmonics of the geopotential retained up to the 4th zonal harmonic. The variations of the elements are averaged over the fast and medium angles, thus retaining only the secular and ...

Low Power LoRa Transmission in Low Earth Orbiting Satellites [PDF]
, 2021 In the recent past, a modulation technique called “LoRa” has become popular in the communication industry due to its long range capabilities with low power consumption, a few satellites have carried LoRa and worked successfully inspite of being skeptical about Doppler shift, packet loss, etc.

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 ...
