Embodiment Construction

[0024] refer to figure 1 , one aspect of the disclosed system 10 includes a power supply 12 that provides input (eg, current, voltage, power) to a controller 14 . In one example, the controller 14 may be an active or passive voltage or current or power output source based on control inputs such as sensor data obtained from a movable platform (e.g., vehicle, boat, aircraft, spacecraft, etc.) ) adjust the voltage, current and / or power level from its input to its output. In one embodiment, controller 14 energizes electrical coils 16 (coils 16 ) to provide a moveable platform (eg Figure 5 Desired functionality on the satellite 190 shown).

[0025] In one embodiment, electrical coil 16 (eg, coil 160 ) includes a figure 2 and image 3 The multi-layer printed circuit board 140 is shown to provide multi-function capability on a mobile platform such as satellite 190 . For example, controller 14 applies a certain level of direct current (DC) to coil 16 (eg figure 2 and image ...

Abstract

A method and system of using a common set of coils to provide at least two of magnetic flux, heat and degaussing in a mobile platform are provided. In accordance with one embodiment, the method involves oscillation of current in the coils at a frequency higher than a defined pointing requirement to provide heat. In accordance with another aspect, the coil functions as a degausser by energizing the coil with an oscillating current that decreases in amplitude over time.

Description

technical field [0001] This application relates to multipurpose electrical coils as flux generators, heaters or degaussing coils, and more particularly to methods of providing magnetic flux, heating and / or degaussing in mobile platforms using a set of common coils. Background technique [0002] In the operation of satellites in stable orbits, there is always a need to control or limit uncontrolled rollovers of the spacecraft. Such runaway motion of a satellite that is expected to be stabilized in orbit makes the satellite effective only for its planned operation. Furthermore, prolonged flipping at excessive angular momentum could compromise the structural integrity of the spacecraft as well as the thermal and power balance of the spacecraft. Therefore, expect the recovery of the satellite to occur a short time after the rollover begins. [0003] Flip control can be accomplished with large propulsion devices such as rocket thrusters or ejectors. The use of such devices to ...
