gLISA: geosynchronous Laser Interferometer Space Antenna concepts with off-the-shelf satellites
, 2014 We discuss two geosynchronous gravitational wave mission concepts, which we generically name gLISA. One relies on the science instrument hosting program onboard geostationary commercial satellites, while the other takes advantage of recent developments ...
