Direct Readout Ground Station (DRGS)

    • Pilot tone (beacon) tracking & DCP demodulators are implemented completely in software on PCs.
    • Implemented entirely in software on the PC
    • Antenna, 5 meter prime focus
    • A single PC supports up to 100 channels of any baud (100, 300 or 1200).
    • No proprietary hardware used in demodulators
    • Integrated feed/LNA/ downconverter (LNB)
    • Multiple PCs can support 100 channels or more! Once the DSR II receiver is installed, standard PCs plus DSR software support as many channels as needed.
    • Control via Windows program or LAN through socket protocol
    • DSR receiver (Digital Satellite Receiver) with a network connection
    • Pilot Tracking DSR Specifications Required PC – 16 Channels
      Dual Pilot Tracking Support The DRGS system tracks 2 pilot signals at the same time. In the event of a failure of the primary pilot signal, the system will perform a ‘NO BREAK’ transition to the backup pilot signal with no loss of data. Currently the system supports the original pilot signal in addition to the new pilot signal found below channel 1. Size Standard 19” rack mount (1HU) Rackmount, desktop or mini-tower design
      Failsafe Tracking Mode The system operates continuously in the event of a failure in both pilots at the same time.In the event of dual failure, the system will track the channel frequency based on averagefrequency reception of the messages on the channel. This yields performance almost asaccurate as the actual pilot based tracking and permits operation indefinitely until NESDIScorrects any problem with the Pilot. Once the Pilots return to service, the system automaticallyswitches over to the original pilot with no loss of data. Supply Voltage 85-250 VAC 1 processor @3.0 GHz or dual processors @1.5GHz with hyper-threading
