NEW DIGITAL-INPUT TRANSMITTER FOR MISSILE TELEMETRY

Abstract

Telemetry for aircraft and missiles has been in use by the military and its suppliers since the 1950’s, using a variety of frequencies and formats. The relative availability and versatility of digital electronics obviates use of pulse-code modulation (PCM) schemes, rather than analog-based formats used more commonly in the past. The digital-input transmitter described accepts binary format directly from a TTL source and has applicability in both standard telemetry and encrypted systems.
