Therefore the team commander will handle the information required for the success of the operation and to avoid any fatalities. It consists of two elements:
Portable system (First Responder): equipped with the AIOSAT advanced positioning system and AIOSAT communication system. The functions of this portable system will be:
- Continuously transmit the position of the first responders. o Allow data communication of the team commander with the firefighters and the Mobile Coordination Centre (MCC) to exchange commands and alerts related to generic mission operations and in particular to prevent rescue workers from entering dangerous locations.
- Firefighters only receive the different sound alerts having not any interaction with the system, brigades and MCC will take advantage of the added value information that AIOSAT provides ensuring also the safety of their dependents.
- Receive required information from the Mobile Coordination Centre (MCC) for positioning augmentation enhancing accuracy (differential correction data on the pseudo ranges) and integrity monitoring techniques, such as different Receiver Autonomous Integrity Monitoring (RAIM) for example eRAIM and ARAIM, mandatory for safety related applications.
Mobile Coordination Centre – MCC: the mobile unit (truck) will be equipped with the AIOSAT positioning system, AIOSAT communication system and AIOSAT TA system. The functions of this mobile coordination centre will be:
- Continuously receive the position of the First Responder cluster (see Figure 1) and track the rescue workers.
- Setup a system to retrieve realtime differential GNSS corrections. The proposed alternative is the use of EGNOS, however to increase the availability of the corrections in harsh environments where EGNOS is not available, NTRIP client (Networked Transport of RTCM via Internet Protocol), such as EDAS is also considered to obtain the differential GNSS corrections.
- Transmit the differential GNSS corrections and integrity over the AIOSAT communication systemTransmit required orders to prevent rescue workers from entering irreversible risky locations (alarms).
- Interface with existing on-board systems and external networks (via SATCOM) to access relevant information needed for the mission, e.g. outdoor and indoor maps.
- Overall management and monitoring of the AIOSAT network and devices.
Supported Use Cases
AIOSAT UC1: tracking the team members
The AIOSAT system will allow the team/brigade commander to track the location, including a confidence margin, the status of the battery and the status of the communication systems of the team members equipped with the AIOSAT portable system.
Moreover, the team/brigade commander will receive messages of a person motionless or entering a dangerous pre-programmed zone.
Related CM functions
AIOSAT UC2: Send commands and alerts to field workers
AIOSAT system will allow the team commander to send commands and alerts to the firefighters and the Mobile Coordination Centre (MCC). This can be, in particular, used to prevent rescue workers from entering dangerous locations.
The information of the task asignment for the first responders and the position of the main hazards (seat of the fire, water hazard, blocking path, proximity to a dangerous substance) could be transmitted to the Mobile Coordination Senter in real time by the team/bridage commander
