Furthermore establish baseline measurement (UCs) conducted organised WP3. UCs involving field applications carried out using distinct from those employed indoor installations. activi-ties at sites (permanent semi-permanent but stationary survey-mode) allow evaluation additional instrumental properties device performance. These include setup time temperature-related issues stability natural environment conditions (e.g. precipitation snow wind). duration required ease instrument handling by operators requirements on on-site power availability versus operation via batteries on-the-fly data processing judge quality measurement must considered. OBQS developed tested firstly laboratory dedicated platforms before being onboard-ed. No flight mission performed capabilities can guaranteed.
