AI summary

The invention is a wireless sensor and telemetry system for use on a vehicle such as an aircraft including at least one sensor node, a gateway, a user control system, data management and analytics means, wherein the sensor node is capable of sensing at least one type of operational performance or structural condition parameter data for the vehicle. Sensor node is attached to the vehicle in a specific location so that the data acquired gives information to the users of the system that relates to the operational performance or structural condition of the vehicle during operation. The sensor node wirelessly transmits the data it acquires to the gateway. The user control system enables person/s, to remotely operate and control the wireless sensor and telemetry system, by sending wireless operational control instructions to the system either via the gateway or directly to a particular sensor node or to a cluster of sensor nodes.
