Broadband satellite multimedia [PDF]

open access: yes, 2010
The broadband satellite multimedia (BSM) architecture standardised by ETSI defines a satellite independent service access point (SI-SAP) interface layer that separates the satellite independent features of the upper layers from the satellite dependant ...

Satellite RNAs and Satellite Viruses [PDF]

open access: yesMolecular Plant-Microbe Interactions®, 2016
Satellite RNAs and satellite viruses are extraviral components that can affect either the pathogenicity, the accumulation, or both of their associated viruses while themselves being dependent on the associated viruses as helper viruses for their infection. Most of these satellite RNAs are noncoding RNAs, and in many cases, have been shown to alter the

Research on BeiDou anti-spoofing technology based on comprehensive radio determination satellite service

open access: yesSatellite Navigation, 2020
The BeiDou system (BDS) plays a significant role in people’s lives, but its security is easily affected by spoofing attacks. The radio determination satellite service (RDSS) is a special service of BDS that provides two-way communication, positioning ...

Spectral Synthesis for Satellite-to-Satellite Translation

open access: yesCoRR, 2020
Earth observing satellites carrying multi-spectral sensors are widely used to monitor the physical and biological states of the atmosphere, land, and oceans. These satellites have different vantage points above the earth and different spectral imaging bands resulting in inconsistent imagery from one to another.

A delay model for satellite constellation networks with inter-satellite links [PDF]

open access: yes, 2009
Within this paper we examine a non-geostationary satellite constellation network with inter-satellite links (ISLs) for global air traffic control (ATC) and air passenger communication (APC).

BOC Signal Acquisition Algorithm Based on Similar Enfoldment

open access: yesInternational Journal of Aerospace Engineering, 2020
A BOC signal has been widely used in the Global Navigation Satellite System (GNSS). Although the BOC signal has many advantages, the autocorrelation function (ACF) of the BOC signal has lots of peaks, which makes signal acquisition difficult.
