Maritime Data Collection and Communications USV

The SeaTrac SP-48 is an open persistent Uncrewed Surface Vehicle (USV) used to efficiently, safely and cost effectively perform real-time data collection and communications in all marine environments. Powered by solar energy with a large payload capacity and power, the platform enables the use of best-in-class combinations of payloads including high-powered sensors during any one mission. The sensor agnostic, low logistic SP-48 is self-righting and can autonomously operate continuously over long durations reducing the risk and costs for marine data collection over conventional methods.
