A magnetorquer or magnetic torquer (also known as a torque rod) is a satellite system for attitude control, detumbling, and stabilization built from electromagnetic coils. The magnetorquer creates a magnetic dipole that interfaces with an ambient magnetic field, usually Earth's , so that the counter-forces produced provide useful torque .
A spacecraft's attitude must typically be stabilized and controlled for a variety of reasons. It is often needed so that the spacecraft high-gain antenna may be accurately pointed to Earth for communications, so that onboard experiments may accomplish precise pointing for accurate collection and subsequent interpretation of data, so that the heating and cooling effects of sunlight and shadow ...
This was in part due to the distance of the spacecraft from the planet, noise within the magnetometer, and a very weak Venusian magnetic field. [2] Pioneer 6, launched in 1965, is one of 4 Pioneer satellites circling the Sun and relaying information to Earth about solar winds. This spacecraft was equipped with a single vector-fluxgate ...
Overview. A spacecraft's attitude must typically be stabilized and controlled for a variety of reasons. It is often needed so that the spacecraft high-gain antenna may be accurately pointed to Earth for communications, so that onboard experiments may accomplish precise pointing for accurate collection and subsequent interpretation of data, so that the heating and cooling effects of sunlight ...
SROSS-C2 or Stretched Rohini Satellite Series C2 was a satellite developed by the Indian Space Research Organisation. It conducted research on Gamma Ray Bursts in Low Earth Orbit. It was launched on 4 May 1994 using an ASLV rocket from Satish Dhawan Space Centre. The first two satellites in the SROSS series failed to attain orbit. The third one ...
The EMFF system is most applicable in cases where multiple spacecraft are free-flying relative to one another and there is no need to control the center of mass of the system. NASA’s Terrestrial Planet Finder (TPF) mission and space telescope assembly are just two such types of missions. EMFF provides the foremost advantage of reduced ...
Professor Brij Agrawal at the Naval Postgraduate School has built two spacecraft simulators, at least one of which uses CMGs: [permanent dead link ] Honeywell Defense and Space Systems performs research in [broken link] Control Moment Gyros They also have developed a spacecraft simulator driven by CMGs: [broken link] CMG Testbed Video
Explorer 32, also known as Atmosphere Explorer-B (AE-B), [2] was a NASA satellite launched by the United States to study the Earth's upper atmosphere.It was launched from Cape Canaveral on a Delta C1 launch vehicle, on 25 May 1966.
