RDMS™ Compact Receivers

Quasonix RDMS™ compact receiver

Airborne Accuracy

Quasonix’s multi-mode compact RDMS™ telemetry receiver features an extremely sensitive RF downconverter integrated with the company’s market-leading ARTM demodulator and bit synchronization in a compact 12 cubic inch flight-ready package. When compared to the competition, RDMS™ offers a remarkable 6 to 8 dB sensitivity advantage. What you choose to do with the extra link margin is up to you.

Key Features

  • Complete Receiver – RF to Bits
    A single-box solution that accepts RF signals, and delivers baseband clock and data. No external add-ons required. 
  • Flight-ready package
    Compact 12 in.³ (4.00″ x 3.00″ x 1.00″) enclosure. 
  • True Trellis Demodulation in all ARTM Modes
    Provides true trellis detection in all three ARTM modes for optimal demodulation. 
  • Lower L, upper L, full S, C, or multiple bands available
  • Lowest noise figure
    3.5 dB noise figure bests all other ARTM receivers on the market, hands down.
