Monitoring and Control of Each Nanosatellite within a Cluster of Nanosatellites

About this technology

Overview

NASA has developed an innovative combination of a Magnetometer, low-powered ElectroMagnets, and Resonant Inductive Coupling (MEMRIC) to create and control relative positioning of nano satellites within a cluster. This is a game-changing approach to enable distributed nanosatellite (nanosat) clusters. The focus is on low-cost propulsion, navigation, and power sharing. Each of these functions can share the same basic technology. With the combination of a magnetometer, low-power electromagnets, and resonant inductive coupling, several nanosats can be clustered without the need of propellant-based propulsion systems, or GPS for relative positioning. By separating distinct subsystems into their own nanosat and producing them as generic, off-the-shelf components, the mission-design process is simplified, enabling the selection of the number of subsystem components that is most beneficial to the mission. The cost saving in the design cycle will pay for the extra, off-the-self power unit.
