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.
Right Now is the title of a number-one R&B single by singer/actor Al B. Sure!. The hit song spent one week at number-one on the US R&B chart and peaked at number forty-seven on the Billboard Hot 100 .
Al B. Sure! has three sons. [11] His eldest son Albert Joseph Brown IV, as Al B. Sure Jr, was featured on the MTV series Rock the Cradle. [11] His second son Devin Brown is a hip hop singer and goes by the name of Devin LOUD. [12] While publicly dating Niki Haris in 1991, he had a son by Porter, Quincy Brown who was later allegedly adopted by ...
We now know that every day, magnetic north traces an elliptical path of about 75 miles (120 kilometers). Since its discovery, magnetic north has drifted away from Canada and toward Russia.
The orbit allowed the satellite to map a majority of the Earth's surfaces except the geographic poles. [3] After launch the payload was brought to an orbit of 96.80° facing the Sun as the Earth rotated underneath. It was kept in a close Earth orbit, with vector magnetometers capable of sensing magnetic fields closer to Earth's surface.
A magnetometer is a device that senses magnetic field strength and, when used in a three-axis triad, magnetic field direction. As a spacecraft navigational aid, sensed field strength and direction is compared to a map of Earth's magnetic field stored in the memory of an on-board or ground-based guidance computer. If spacecraft position is known ...
