HySpex Mjolnir VS-620

For applications requiring low mass, combined with high-performance specifications and scientific grade data quality on the full VNIR-SWIR range, HySpex Mjolnir VS-620 is an ideal solution. Sharing the onboard data acquisition unit and navigation system, HySpex Mjolnir VS-620 is both space-efficient and cost-effective.

The VNIR and SWIR optical axis are coaligned in the along-track direction, assuring perfect coregistration in the flight direction. In addition to the high-quality hyperspectral data cube, covering the spectral range from 400 - 2500 nm, with 490 bands, double resolution data in the VNIR range is always readily available. With smile and keystone less than 0.1 pixels for each spectral range, the merged Mjolnir VS-620 data product will have coregistration/keystone better than 0.2 pixels for the full VNIR-SWIR range.

HySpex Mjolnir VS-620 configuration

UAV - BFD XQ-1400S

HySpex can be mounted on any UAV platform capable of lifting the total payload.

  • BFD XQ-1400S provides ~30 min. flight endurance with Mjolnir payload
  • Ground control software for advanced flight plans
  • High stability in wind

GIMBAL

The advanced 3-axis digital stabilizer, gStabi H16, weighs only 2.2 kg (4.85 lbs). NEO delivers the gStabi H16 with a circular quick release, allowing it to be seamlessly fit on a wide range of multi-rotors. Capable of handling payloads up to 7 kg (15.43 lbs), the gimbal can support all HySpex Mjolnir models.

  • Gimbal and Mjolnir powered by the same battery
  • Encoder with resolution up to 0.005°
  • Ultra accurate IMU sensor with temperature compensation

APPLANIX APX-15/20 UAV

  • Advanced Applanix IN-FusionTM GNSS-Inertial integration technology
  • 100 Hz real-time position, roll, pitch and heading output for direct georeferencing of sensor data
  • IMU data rate 200 Hz
  • 336 Channels (GPS, GLONASS, BeiDou, Galileo, QZSS, SBAS)
  • Solid-state MEMS inertial sensors w/Applanix SmartCalTM compensation technology
  • Unfiltered, unsmoothed pseudo-range measurements data for low noise, low multipath error, low time domain correlation, and high dynamic response

UAV configuration

All Mjolnir systems can easily be deployed for fieldwork by mounting it on a tripod with a rotation stage.

  • Lightweight, robust, compact and self-contained design
  • Working distances: 20 m –
  • Can be fully battery powered
  • Quick mounting and easy operation with scan speed fully synchronized with the camera frame rate
  • Easy wireless operation from tablet or laptop

A 1m close-up lens is also available for closer range ground measurements.
