ACTS has been used for a bunch of stuff, but you're probably thinking of the
high data rate experiments. The home page for ACTS HDR is

You'll find this on on the Experiments page, number 101.

Well, maybe. ACTS is a GEO satellite, and interactive use is painful. On the
other hand, it's enabled people to do interesting things with bulk data
transfer, and it was probably the first system that got you OC-12 across
any significant distance. There's an IETF WG working on the issues posed by
IP over satellites, whose home page is http://www.isr.umd.edu/CSHCN/Links/IPoS/
