The JAS 150 Digital Airborne Scanner

Gerald Albe ASPRS Conference 2007

Jena Airborne Scanner (JAS) Advanced Linescanner Design

… for Photogrammetry and Remote Sensing:

» Resolution 5cm (2 inches) from 1000m flight altitude within reasonable airspeeds » Up to 3cm (1.2 inch) geo-location accuracy » All multi-spectral bands in full resolution » Compatible with existing peripherals and platforms •Nine CCD lines are scanning the surface.

•Multi-spectral Bands: RGB and NIR •Four stereo lines and nadir avoid blind spots especially in cities.

JAS Advantages for our Customers

  Highest resolutions, highest accuracy ensure competitiveness for the next 10 years.

The total cost of ownership are considerable lower because of the easy and robust design.

  The JAS150 is compatible to the most used peripherals.

The pushbroom scanner design with its near-orthogonal view allows cost-effective capturing of Orthophotos and near true Orthophotos as well as capturing all multispectral bands in full resolution for remote sensing applications.
