Application of cloud particle sensor sondes for estimating the number concentration of cloud water droplets and liquid water content: case studies in the Arctic region [PDF]

open access: yesAtmospheric Measurement Techniques, 2021
A cloud particle sensor (CPS) sonde is an observing system attached with a radiosonde sensor to observe the vertical structure of cloud properties. The signals obtained from CPS sondes are related to the phase, size, and number of cloud particles.

ON CONTROL OF TETHERED SATELLITE SYSTEMS

open access: yesIFAC Proceedings Volumes, 1985
Abstract The dynamics of tethered satellite systems is rather complex and consists of various rotational and vibrational degrees of freedom. While designing its control system, some of these degrees of freedom may be modeled while the others are likely to be left unmodeled to reduce complexity and cost.

The flight of the tethered satellite system

open access: yesEos, Transactions American Geophysical Union, 1992
The first Tethered Satellite System (TSS‐1) Electrodynamics Mission is scheduled for launch aboard the space shuttle ST‐46 on July 31, 1992, as a joint mission between the United States and Italy. A 500‐kg, 1.6‐m‐diameter satellite, attached to the shuttle by a thin (.24 cm), conducting, insulated wire (tether), will be reeled upwards from the orbiter ...

Dynamics and Control of Tethered Satellite System in Elliptical Orbits under Resonances

open access: yesInternational Journal of Aerospace Engineering, 2020
This paper studies resonance motions of a tethered satellite system (TSS) in elliptical orbits. A perturbation analysis is carried out to obtain all possible resonance types and corresponding parameter relations, including internal resonances and ...
