Lake flights to explore water/air interface

Headwall Photonics' integration partner Alava Ingenieros is aiming to provide a completely integrated airborne remote sensing solution, using the Micro-Hyperspec VNIR sensor.

The Swiss educational establishment Ecole Polytechnique Federale de Lausanne is sponsoring an exploration programme featuring a sensor-packed ultralight aircraft that will analyse the phenomena occurring at the interface between air and water.

Flights are underway over Lake Geneva in Switzerland, and will be repeated over Lake Baikal in Russia later this year. The airborne technology will allow scientists to gather data concerning bacteria, sediments, and dissolved gasses. While satellites can analyse these variables now, low-flying ultralight aircraft can collect this data more precisely and put it into the hands of researchers sooner.

Micro-Hyperspec is a remote sensing instrument specifically designed for high-resolution spectral and spatial imaging aboard small, tactical airborne vehicles. It provides excellent spatial and spectral resolution and a wide field of view, meaning a more efficient flight path over areas of interest.

Alava is packaging Micro-Hyperspec with the software needed to handle radiometric calibration, flight data acquisition, ground data acquisition, atmospheric correction, and post-processing of the hyperspectral data.
