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 ...
Former Space Systems Lab associate director Dr. Raymond Sedwick (now at the University of Maryland, College Park) has been awarded the first Bepi Colombo Prize for a paper on electromagnetic formation flight. According to Aero-Astro Professor Manuel Martinez-Sanchez, who worked with Colombo and was a juror in the competition, "The jury was ...
A control moment gyroscope (CMG) is an attitude control device generally used in spacecraft attitude control systems. A CMG consists of a spinning rotor and one or more motorized gimbals that tilt the rotor’s angular momentum.
The Spacecraft Magnetic Test Facility is located about 2 miles (3.2 km) east of the main campus of the Goddard Space Flight Center, in Building 310-20 on the north side of Good Luck Road. The building is a single-story structure, 60 feet (18 m) square, and is built entirely out of nonmagnetic materials.
