Abstract Energetic particles represent an important component of the plasma in heliosphere. They range from accelerated at impulsive events solar corona and large scale structures interplanetary medium, to anomalous cosmic rays boundaries In-situ satellite observations, numerical simulations theoretical models have advanced, often a cooperative way, our knowledge on acceleration processes invol...

Virtually all Satellite Laser Ranging (SLR) stations produce a real-time display known as an Observed-Minus-Calculated (OMC) plot. In such a plot, illustrated in Figure 1, the horizontal axis displays the elapsed time during the track while the vertical axis displays the measured ranges to the target plus any false alarms as points on the plot. The vertical axis is dynamically centered on the p...

Satellite thermal control ensures safe operating temperature ranges for satellite components throughout the mission life. Effects of altitude, spin, and position of satellite radiator(s) on the thermal control of a small Low Earth Orbit (LEO) satellite have been studied. Results show that change in satellite altitude, in the range considered here, does not produce critical thermal conditions. H...

Abstract In this work, the Precise Science Orbit (PSO) of Gravity Field and Steady-State Ocean Circulation Explorer Mission (GOCE) satellite, acquired via European Space Agency, served as reference orbit for testing various variants GOCE satellite modeling. The positions along reduced-dynamic PSO were treated pseudo-observations in improvement process least squares sense. This was realized usin...

Countermeasure for round trip delay which occurs in between satellite and ground with network accelerator is investigated together with operating system dependency on effectiveness of accelerator. Also disaster relief data transmission experiments are conducted for mitigation of disaster together with acceleration of disaster related data transmission between local government and disaster preve...

In sport science, Global Navigation Satellite Systems (GNSS) are frequently applied to capture athletes' position, velocity and acceleration. Application of GNSS includes a large range of different GNSS technologies and methods. To date no study has comprehensively compared the different GNSS methods applied. Therefore, the aim of the current study was to investigate the effect of differential ...
