11 – Use of ultrasonic waves to transfer data, alarm, and follow operators in the launch zone 

Name of the system:

Use of ultrasonic waves to transfer data, alarm, and follow operators (geolocation and authentification) in the launch zone.

Lead entity within the SAMMBA consortium:

Air Liquide (reach out to us here)

Attachment point within the process chain of the Spaceport operator:

Systems using ultrasound waves can be used to collect data from sensors, detect workers in the launch zone area, and to send alerts, data, or alarms to employees. Attachment points with the spaceport are propellant storage tanks and the fluid handling system.

Major benefit within the process chain:

The use of ultrasonic waves to transfer data has benefits for the safety of operations, data security, and the business case of spaceports. Safety is increased as the concept allows operators to work in a safe environment by using equipment with a high/higher degree of equipment for potentially explosive atmospheres (ATEX) compatibility. Alerts to workers via ultrasonic waves help to move workers out of the danger zone faster. In addition, the concept reduces the time spent by operators in the dangerous launch zone. Costs can be reduced by lowering the risk of launch postponement, abortion, or delay due to sensor anomalies.

Anticipated R&D vector for the near/mid/long-term:

Further research is required to mature the concept and to ensure that the system has no negative impact on other systems, e.g., via interference.

Modularity granted with the following standards:

The use of ultrasonic waves might require minor modifications to the fluid system in order to be used at any spaceport.

Interoperability granted with the following standards:

Standardised data transmission is required when transmitting information via ultrasonic waves.

Systems interfaced:

Depending on the implementation, the system is interfacing with propellant storage tanks, the fluid management systems as well as the launch control center when being used for worker/operator safety applications.
