ETS 6
Also called Kiku 6
Was designed to demonstrate amongst other things ion propulsion and liquid
bi-propellant GEO orbit insertion. The payload would have supported mobile
communications and inter satellite communication at radio and laser frequencies
in preparation for Data Relay and Tracking Satellite systems.
In mid-1995 it was reported than successful intersatellite communication had
taken place with
UARS
Later in early 1996 bidirectionel laser communications between JPL and the
satellite were carried out.
