SASISA (Small-Aircraft Service for Instant Situational Awareness) is an ARTES 20 Demonstration Project for establishing a reliable, affordable and commercially viable airborne sensing service for first responders and other civil security-sector users to supply them with a new dimension of situational awareness information in the most critical initial phase of disaster response operations.
In current practice, airborne sensing is a non-real-time activity, with results often only available days later. The SASISA service's near real-time delivery of georeferenced imagery offers transformational change for improved emergency response, while complying with established operational modes and financial limitations of civil public sector user agencies.
For airborne situational awareness support, SASISA combines existing technologies in a flexible, modular system that is designed to make the benefits of digitally networked, integrated technology available to civil emergency and disaster response communities in the EU.
Capabilities are demonstrated in realistic demo utilisation deployments in several countries to strengthen awareness, acceptance and support of the new service in emergency and disaster management communities, based on the integrated use of applied space technologies.
The demonstration system uses a Diamond DA42M multi-purpose small aircraft with pilot and operator, carrying a multisensor payload for still and moving images. Images are orthorectified on board and downlinked for visualisation in near real time during the mission over a Viasat Ku-band airborne satellite terminal for in-flight beyond line-of-sight Internet connectivity.
This enables the Mapping Production Centre at e-GEOS to generate integrated value-added post-processing products from aerial and satellite data, to and deliver them to users significantly faster than current rush-mode services.
The SASISA service is designed for institutional users in the civil security sector with responsibility for disaster and emergency response and humanitarian assistance. The focus is on the European Union, but the geographical scope is not limited.
The participating and contributing users in the SASISA Demonstrations are:
To respond to disasters, users need
Bringing the benefits of real-time airborne sensing to the civil security sector empowers responders and lets them handle emergency situations more effectively and more confidently.
Relevant usage scenarios include:
Responding to landscape-changing disasters (e.g. landslide, earthquake).
Both participating Austrian user agencies operate a state-wide alarm centre with the task to coordinate and direct emergency response operations based on an integrated situational picture. In practice, they lack the means to establish this picture quickly enough, at the risk of missing opportunities to save lives or putting first responders into unknown danger.
Disaster scenarios reveal the need to reduce the gap between available resources and the capabilities required by the users' given objectives: gain situational awareness for mission control and decision-making; understand the dynamics and risks of the given situation; identify the right measures to minimise damage to humans, property, infrastructure and the environment.
Real-time airborne sensing empowers responders and lets them handle emergency situations more effectively and more confidently. Realising the importance of satisfying the described needs, emergency.lu works toward integrating airborne situational awareness with imagery and maps in its own service offerings for disaster response management.
The modular system architecture with various sensor payloads and satellite communication beyond line of sight permits fast, effective emergency response and also facilitates other commercial utilisations of the same aircraft between activations in disaster events.
The solution demonstrated in SASISA offers three main benefits:
The airborne SASISA service uses two space technologies (Telecommunication and Navigation) and in addition, its operation and resulting data are closely combined with space-based Earth Observation to produce an integrated service and suite of products for users.
These three space technologies enable decisive improvements over current practices in terms of timeliness, reach and quality of situational awareness information.
High-resolution Earth observation from satellites (radar and optical) is already established as a key enabler for European emergency management, and can be further strengthened by integrating it with an in situ instant-reaction airborne element that also improves performance under cloud cover and adds rapid oblique-view capability.
Airworthiness of the DA42M aircraft "G-PEEK" with the specialised SASISA mission payload configuration was certified by EASA in March 2015. This is the regulatory precondition for using it commercially.
Trials in support of integrating and testing the image capturing, processing, transmission and visualisation workflows were performed successfully in 2014/15.
The first SASISA demonstration deployment campaign was combined with a large, multi-scenario exercise on 15/16 May 2015, led by the Austrian Red Cross and the Lower Austrian civil protection agency, at Allentsteig training ground in Austria.
The second demo campaign was performed with the Italian National Civil Protection Department on 20/21 July 2015, operating the aircraft from Rome and covering wildfire scenarios in Campania and Calabria. More than 20 active wildfires in Southern Italy were spotted, captured and reported during the mission.
Key achievements of the project include:
The project was concluded with the Final Review meeting on 17 December 2015.
