Mjolnir S-620

The HySpex Mjolnir S-620 hyperspectral imaging system for UAVs is the SWIR version of the Mjolnir camera series. Similar to the VNIR version, it provides a unique combination of small form factor and low mass, combined with high-performance specifications and scientific grade data quality.

With a weight of less than 4.5 kg and less than 50 W power consumption, HySpex Mjolnir S-620 is very well suited for a wide range of UAVs.

NEO offers high-performance unmanned aerial vehicles, fully integrated with the HySpex Mjolnir S-620. The UAV is fitted with a standard battery package allowing up to 30 minutes of flight time. All HySpex Mjolnir systems can also be mounted on a tripod and rotation stage for ground use.

HySpex Mjolnir S-620 configuration

UAV 

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

  • BlackSquare X8 multi-rotor provides great flight endurance with Mjolnir payload
  • Ground control software for advanced flight plans
  • High stability in wind

GIMBAL

NEO recommends using a gimbal, to compensate for the pitching of the multicopter. The advanced 3-axis digital stabilizer weighs only 2.63kg (5.8 lbs). NEO delivers the AEVO with an anti-vibrational mount and circular quick release, allowing it to be seamlessly fit on a wide range of multirotor platforms. Capable of handling payloads up to 9 kg (20 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.
