Product Information

The Trimble Digital Sensor System (DSS) 439 is a complete end-to-end solution for producing highly accurate, high-resolution color and CIR digital orthophotos and orthomosaics.

The system uses a 39-megapixel, metric, medium-format camera, GNSS-aided inertial technology, flight management system, and complete software workflow to generate ortho and stereo products for fast and efficient mapping. User-interchangeable lenses (40mm, 60mm, 250mm) allow flexibility in flying height and field of view, along with RGB and CIR configurations. DSS is certified as mapping-grade by the USGS.

Features

  • Simple to use, yet highly accurate: Rugged system architecture is shock, vibration and pressure tested—perfect for airborne environment
  • Mapping grade camera: USGS certified, calibrated, stable over time
  • Direct georeferencing: AT (Aerial Triangulation) not required
  • Choice of Inertial Measurement Units (IMUs)
  • Professional installation, crew training, and 2 years of ongoing customer support included with every system
  • Flexibility: Custom lenses and lens-mount configuration allows for easy removal and replacement, in flight, without recalibrating
  • Modular, expandable, customizable system. Can be flown with:
    • Dual cameras for greater productivity
    • Simultaneous CIR/NIR, or VIS/Hyperspectral
    • Laser scanner
    • Oblique camera
    • Rapid ortho development
  • Pilot controlled operation: Built-in automated Flight Management System (FMS)
  • Quick data turnaround: End-to-end digital processing and direct data import into photogrammetric and GIS systems

System Components

Trimble DSS integrates all the hardware and software components required for aerial imaging with high accuracy, reliability, and ease-of use. A typical configuration includes:

  1. Applanix POSTrack touch screen: allows users to pre-plan flight paths and reduce flight times to fly missions

  2. Camera: mapping grade quality; USGS certified; Camera Sensor Head (CSH) has fully calibrated camera/digital back/exoskeleton assembly

  3. Inertial Measurement Unit (IMU)

  4. Azimuth Mount: single axis, automatically controlled mount; 3-axis stabilized mount also available with built-in Inertial Measurement Unit

  5. Flight Management System: integrated Applanix POSTrack Flight Management System (FMS)

  6. Data Storage Unit (DSU): removable, pressurized and temperature - controlled ruggedized disk drive; 7000 image capacity per drive (2 supplied, 500 GB each)

  7. Camera Computer System (CCS): electronically guides all assets for airborne environment

  8. Applanix POS AV Direct Georeferencing System: specifically designed for direct georeferencing of airborne sensor data

  9. Power Distribution Unit (PDU): controls power to all systems and provides an LED display to the operator

  10. Trimble INPHO software: high processing speed and automation in orthophoto and mosaic production, DEM extraction, and seamlessly integrated with the Trimble DSS workflow

  11. Applanix POSPac MMS software: post-processing software bundle; includes mission planning software, carrier phase DGPS processing, integrated GNSS+Inertial processing, photogrammetry tools for EO generation, IMU boresight calibration and quality control, Trimble DSS tools for mission management and image development
