Satellites of Satellites: The Case for Carina and Fornax [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 Abstract We use the Auriga cosmological simulations of Milky Way (MW)-mass galaxies and their surroundings to study the satellite populations of dwarf galaxies in ΛCDM. As expected from prior work, the number of satellites above a fixed stellar mass is a strong function of the mass of the primary dwarf.

Satellite RNAs and Satellite Viruses of Plants [PDF]
Viruses, 2009 The view that satellite RNAs (satRNAs) and satellite viruses are purely molecular parasites of their cognate helper viruses has changed. The molecular mechanisms underlying the synergistic and/or antagonistic interactions among satRNAs/satellite viruses, helper viruses, and host plants are beginning to be comprehended. This review aims to summarize the

Satellite RNAs and Satellite Viruses [PDF]
Molecular 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

Sea Surface Temperatures Derived From COCTS Onboard the HY-1C Satellite
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021 As one of the key payloads onboard the HY-1C satellite, the Chinese ocean color and temperature scanner (COCTS) was designed for global sea surface temperature (SST) and ocean color detection.

Spectral Synthesis for Satellite-to-Satellite Translation
CoRR, 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.

BOC Signal Acquisition Algorithm Based on Similar Enfoldment
International 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.

EURASIP Journal on Wireless Communications and Networking, 2008 The call for papers resulted in a high number of submis- sions, from which we have been able to select 12 excellent papers dealing with the different aspects of satellite commu- nications and navigation. Multiple-input multiple-output (MIMO) techniques are attracting a considerable amount of attention from within the terrestrial wireless community. The

Dual Quaternion Based Close Proximity Operation for In-Orbit Assembly via Model Predictive Control
International Journal of Aerospace Engineering, 2021 This paper studies the problem of guidance and control for autonomous in-orbit assembly. A six-degree-of-freedom (6-DOF) motion control for in-orbit assembly close proximity operation between a service satellite and a target satellite is addressed in ...
