The interception and analysis of signals transmitted from test-fired missiles. Throughout a flight downrange, a test missile will broadcast information to engineers who monitor its performance. Before the introduction of international verification procedures, countries often encrypted the telemetry to prevent interception. Initially TELINT was picked up by ground stations or surface platforms such as warships, but the development of satellite surveillance technology enabled interception to be conducted from orbiting RHYOLITE platforms.
