This document discusses the integration of Unmanned Aerial Systems (UAS) in atmospheric research, particularly focused on predicting environmental crises such as volcanic ash incidents. It covers the generic mission flow, the advantages of UAS, and specific mission examples, including real-time data collection and analysis. With capabilities like high endurance and controllability, UAS serve as critical tools for timely responses to atmospheric disorders. The session was held at the Volcanic Ash Crisis Seminar 2010 in Belgrade, highlighting advancements in flight control, mission planning, and data management.

Content • Generic mission flow of a UA mission • Advantages of UAS in Atmospheric Research • Example Mission • Future UA • Ground Control Station • Volcanic Ash Crisis Seminar 2010
Generic mission flow for a UA in Atmospheric Research Takeoff and landing at the same airport Flight in high altitude (> FL400) to mission area (atmospheric disorder) Loiter at mission area to collect sensor data, duration up to four days Real-Time analysis of collected sensor data is sent to GCS for further evaluation
Advantages of UAS in Atmospheric Research • Reusable - UA can be used multiple times • Controllable - flight parameters (heading, speed, altitude) can be changed during mission • High endurance - UA have an endurance up to 30 hours which will rise up to 10 days in the next few years • Lower risk - no direct human involvement, e.g. tornado research • Immediate data analysis - data obtained from payload sensors can be analysed in real-time; that gives the opportunity to react very quickly on and change mission parameters
Example mission for a UA in Atmospheric ResearchVolcanic ash detection • Takeoff / Landing from several airports in Europe • Climb to affected altitude • Real-time analysis of ash particle density along main ATS routes • Based on results specific routes can be approved for flight operations • Small amount of UA sufficient to cover European continent
Properties of suitable UA for atmospheric research Example Boeing “Phantom-Eye” • Wingspan: 150ft (46m) • Service ceiling: 65.000ft (~20km) • Cruise speed: 150kts • Payload: ~200kg • Endurance: more than four days (larger version with endurance up to ten days in development) • Propulsion: two 2.3 litre motor vehicle engines with 150hp each (1) Picture of NASA “GlobalHawk Atmospheric Research UA” - Property of NASA (2) Picture of Boeing „Phantom Eye“ - Property of Boeing
UA Ground Control Station Consists of several modules: • Flight Planning - Mission • Flight Control • Payload control: • Fusion, evaluation, analysis and interpretation of incoming sensor data • Immediate availability of respective results • Surveillance of sensor performance Picture of future GCS - Property of Raytheon
