To enable serviceable satellites and persistent orbital platforms, the need exists for simple, robust and lightweight modular interfaces. Such interfaces allow for a variety of functions to be upgraded at low-cost using affordable commercial satellite servicing vehicles. Given the large number of LEO constellations in development, such modular interfaces provide a low-cost way of restoring degraded functionality, enabling constellation operators to extend the productive lifetime of their satellites (e.g. plug-and-play modules for replacement batteries, reaction wheels, etc). This eliminates the need to de-orbit and replace satellites which otherwise may be completely functional.
Altius has developed an electropermanent-magnetically coupled electrical and/or fluid connection “MagTag™” interface that is robust and lightweight. The proposed MagTag interface provides the following benefits:
These interfaces will allow for enhanced serviceability and upgradability of future space assets for NASA, DoD, and commercial interests.
The MagTag offers a highly modular, lightweight, and capable interface that is suited for the following NASA applications:
