Building on the Work of THEMIS

The MMS mission will expand on the work of the previous THEMIS missions. The four satellites will fly in formation and be able to maintain their alignment with respect to each other by using GPS and sharing their location data with each other. Before I moved on to work on the ASTRO-H mission, I worked on the development of the prototype GPS receivers and other navigation radios for MMS.

  1. I’m confused – I thought Themis was a conspiracy against Kimberlin and his ilk. Is he claiming satellites are being used in some sort of anti-“progressive” surveillance scheme? And that MMS is a current expansion of that program? ;>
