The Dartcom X-Band EOS System comprises the following:

Outdoor equipment
  • 2m diameter radome with hydrophobic coating to minimise signal loss caused by standing water during rainfall.
  • 1.5m prime focus aluminium parabolic dish antenna.
  • Rotator/pedestal and controller (land-based and marine options).
  • Scalar feed horn and low-noise block downconverter (LNB).
  • Rugged, weatherproof GPS antenna (mounted outside radome).
  • Optional radome environmental control unit for hot climates.

All outdoor equipment is housed in the radome, except the GPS antenna which is mounted externally.

Indoor equipment
  • Modular receiver rack.
  • Demodulator.
  • Uninterruptible power supply (UPS).
  • Optional temperature sensor unit.
  • Ingest and processor PCs.
  • Optional visualisation PC.

All units are rack-mountable and can be supplied in an optional floor-standing cabinet for a complete rack-mounted system.

Features

  • Automatic data reception from Terra, Aqua, Suomi-NPP, JPSS-1 and FengYun-3A/B/C (FY-3) X-Band Earth observation satellites.
  • Complete end-to-end solution with automatic data processing to level 0, 1 and 2 (currently level 0 and 1 only for FY-3).
  • Affordable to meet the limited budgets available for X-Band systems in universities and research institutions.
  • Simple installation with minimal civil engineering works.
  • 1.5m antenna system enclosed in a radome to allow normal operation at wind speeds up to 185km/h (100kt or 115mph).
  • State-of-the-art RF components, allowing good data reception from 15° satellite elevation. In practice good quality data can be received from Terra, Suomi-NPP and JPSS-1 at 7° elevation and from Aqua and FY-3 at 5°.
  • Automatic daily prediction data updates from the internet.
  • Optional temperature monitoring for radome and equipment rack with automatic tracking lockout if limits exceeded.
  • All external components designed and treated to survive tropical and marine environments, with at least IP65 protection rating.
  • Modular construction for easy maintenance and future upgrades.
  • Comprehensive hardware and software diagnostics at all levels.
  • Cost-effective migration path for existing L-Band systems to the next generation of X-Band Earth observation satellites.
  • Combined X/L-Band option allowing reception from X-Band and L-Band satellites using the same antenna system.
