High resolution and high speed, combined with low weight and power consumption, make NEO’s HySpex cameras very well suited for airborne data acquisition.
Position- and attitude logging systems (IMU/GPS) from leading manufacturers can be integrated and supplied with the cameras. Alternatively, the HySpex systems can be interfaced with the customer’s existing navigational hardware.
For airborne systems, NEO supplies dedicated software and a touch screen for ease of operation. A high performance rack computer is standard, but customized light-weight computers are available for smaller aircrafts, UAV's etc.
Airborne Data Acquisition Unit
A customized high performance DAU is supplied to ensure the fastest possible data rates, and easy operation from the day of installment.
The DAUs will be completely assembled and all necessary software and drivers (for e.g. camera, scanning stage) as well as hardware (e.g. frame grabber) will be installed and correctly configured on the computer. The computer will be equipped with the customized HySpex interface, set-up to accommodate up to two HySpex cameras. As the camera is powered directly from the data acquisition unit, no external camera power supply is needed.
To accommodate any aircraft platform preferred by the end-user, NEO offers a selection of DAUs ranging from ultra-compact, low power DAUs to 19” rack solutions.
All HySpex Airborne DAUs are equipped with frequency dividers to correctly register INS/GPS data to the acquired HySpex flight lines.
A daylight readable, high performance touch screen is recommended for airborne operations. The airborne data acquisition software is designed for a touch interface.
To mount the cameras for airborne applications, NEO has designed a variety of mounting plates to fit the available space and/or existing equipment in the customer's aircraft.
Mounting plate for stabilized platform
RT-GEO is a real time processing software. Originally developed for HySpex ODIN in the SYSIPHE project, RT-GEO will be available for all HySpex models and has been adapted for the HySpex Mjolnir cameras to allow real time visualization of results for the drone operators.
RT-GEO allows real-time georeferencing, NDVI, CRX Anomaly Detection and spectral angle mappers, all computed real time, allowing the user to switch between views/detection results. More algorithms will be added in the future, and the framework will be configured to allow user input algorithms.
ReSe - Remote Sensing Applications
The field expander doubles the pixel FOV (along and across track) as well as the total FOV of the camera. The field expander is easily mounted onto the camera by the user, and is available for all classic HySpex models.
Prior to delivery, the camera will be calibrated with the field expander.
Why Field Expander?
The benefits of the field expander are mainly related to cost of the airborne campaign:
- Increasing the field of view increases the ground area covered for a given flight time.
- Air speed can be increased for the same flying altitude.
