The General Dynamics SATCOM Technologies Digital Tracking Receiver (DTR) is a fully synthesized tracking receiver developed for satellite tracking and uplink power control applications. This DSP-based receiver accepts wideband RF inputs, performs frequency selection, and digitally processes the selected signal.

  • L-band range of 950 - 2050 MHz
  • L,S,C,X,Ku, and Ka-band single and multi-band configurations available
  • Single/Dual direct-connect polarization inputs
  • Wide input signal dynamic range (70 dBm nominal)
  • Outstanding sensitivity (minimum C/No is better than 35 dB-Hz)
  • Fully synthesized tuning with 1 kHz tuning steps
  • User-selectable tracking slope
  • Spectral Display

 

Product Details

Features

The DTR can be configured for numerous input frequency ranges from L-band to Ka-band. Multi-band applications are also readily accommodated. DDS techniques facilitate 1 kHz frequency resolution for any input frequency range.

The use of DSP technology, rather than conventional analog radio techniques, provides outstanding linearity and operational flexibility. Software controlled signal detection can accommodate virtually any modulation scheme.

A powerful and intuitive user interface provides the ability to custom configure specific applications in a very straightforward manner. The user settings provide easy configuration of tracking signal slope to match a wide range of next-level system components. A “Spectral Display” function allows the user to view real time amplitude vs. frequency data.

The flexibility and unparalleled attributes, resulting from state-of-the art concepts and components, places the DTR at the forefront of receiver technology.

  • Contextual menus, spin knob and keypad aid user interaction
  • Monopulse capability (optional)
  • Excellent tracking signal linearity
  • Absolute input power level display
  • Serial and parallel remote control capability (contact closure; RS-232, RS-422)
  • Front Panel 70 MHz monitor port (50 Ω BNC female)
  • Bandwidth filter options as low as 16 kHz to maximize C/No
  • Bandwidth filter options for standard configurations as wide as 500 kHz to supported modulated carriers
