Measurement Technics

Equipment

The measurement system consists of a NaI detector with a volume of 16.8 l; a spectrometer with 256 channels and automatic gain control;industrial computers for the control of the measurements, for data collection, processing and storing. For positioning a GPS receiver is used. Together with the spectra and the position, air pressure, air temperature and radar altitude of the aircraft is stored. The data is processed and mapped online during the flight. The measurement system is installed in a Super Puma helicopter of the Swiss Air Force. This helicopter provides very good navigation tools and allows emergency missions also in bad weather conditions.
