High Impact G-Loading Data Acquisition System (HI-G-DAS)

A system is proposed for high-performance wireless data acquisition in high-impact environments, specifically the launch environment of Naval payloads. The High Impact G-Loading Data Acquisition System (HI-G-DAS) is a miniature, low power instrumentation system designed to maximize flexibility by combining precision data gathering capability, user programmability, and long battery life. HI-G-DAS will use state of the art techniques for component selection, PCB design, and modeling of critical elements to withstand acceleration on the order of 1000 g's. The robust system will be capable of interfacing with multiple types of sensors through the use of proven modular techniques and channel-specific programmability. Using wireless communication and battery charging techniques, the system can be fully protected from water ingress in harsh sea conditions. Additionally, its automated underwater beacon will help to locate the device in the event that recovery is necessary. The use of standard software & hardware interfaces as well as common wireless protocols will help to ensure that operation of the system is simple and intuitive.
