Quick Reference

A mode of spacecraft communications that uses two ground stations. One station receives a downlink from the craft, and the other station provides an uplink. For example, a three-way situation would occur if a spacecraft approaching Australia sent telemetry to a deep-space network (DSN) station in that country, while still receiving an uplink from a station in the USA.
