4 Frequently Asked Questions about “Tethered Solar Power Station Satellite - ID Solar Energy Systems”
What is tethered SPS?
Ishimura and Higuchi (2008) studied the coupled phenomenon among attitude motion, tether vibration, and orbital motion by treating Tethered SPS as a tethered satellite system (two tip particles connected by a massless spring). Li et al. (2018) established a dynamic model of Tethered SPS by simplifying the solar panel as a rigid body.
Is tethered SPS a dynamic system?
A new dynamic model of Tethered SPS is proposed based on ANCF and the orbit-attitude-vibration coupled dynamic phenomena are studied. Simulation results revealed that the attitude of the system is unstable when the mass of the bus system is relatively small, because the attitude of the solar panel is in an unstable equilibrium point.
Are non-space-based power beams included in NASA's SBSP project?
Countries with non-space-based power beaming efforts are not included. The idea of SBSP is not new to NASA, which conducted feasibility studies first in the 1970s (NASA & DoE, 1980) and again in the 1990s (Mankins, A fresh look at space solar power: New architectures, concepts and technologies, 1997).
Which space systems have significant mass and solar panel area?
To provide context, consider two examples of space systems with significant mass and solar panel area: an aggregated mass, the International Space Station (ISS); and a distributed mass, a constellation of 4,000 Starlink v2.0 satellites4. The solar panel area is 11.5km2 for RD1 and 19km2 for RD2.
