Method of Tower-less Calibration for Phase Parameter of Tracking System
MATEC Web of Conferences, 2015 This paper introduced the principle of angle errors in tracking system. The demodulation was only related to signal envelop, and supported the phase calibration of radio star.

Assessment of tomographic window and sampling rate effects on GNSS water vapor tomography
Satellite Navigation, 2023 The ground-based Global Navigation Satellite System (GNSS) water vapor tomography is increasingly important in GNSS meteorology. As the multi-GNSS and more ground-based GNSS sites can be incorporated into the regional water vapor tomographic model ...

Culture conditions influence satellite cell activation and survival of single myofibers [PDF]
, 2018 Single myofiber isolation protocols allow to obtain an in vitro system in which the physical association between the myofiber and its stem cells, the satellite cells, is adequately preserved.

Amplification and adaptation of centromeric repeats in polyploid switchgrass species. [PDF]
, 2018 Centromeres in most higher eukaryotes are composed of long arrays of satellite repeats from a single satellite repeat family. Why centromeres are dominated by a single satellite repeat and how the satellite repeats originate and evolve are among the most

On the Orbits of Infalling Satellite Halos [PDF]
, 2010 The orbital properties of infalling satellite halos set the initial conditions which control the subsequent evolution of subhalos and the galaxies that they host, with implications for mass stripping, star formation quenching, and merging.

2021 IEEE International Conference on Communications Workshops (ICC Workshops), 2021 Twenty years of technological improvements have raised once again the question of the economic viability of offering Internet access from space using non-geostationary orbits (NGSO). Trying to answer this question, many established satellite operators (e.
