The U.S. Air Force Battlefield Air Operations (BAO) has established a requirement for portable environmental observations that replicate the automated gathering and reporting of the same measurements currently performed by the AN/TMQ-53 for Service Level D airfield support. To address this need, ISI proposes to enhance our existing Macro Weather Sensor (MaWS) system to meet and/or exceed current AN/TMQ-53 capabilities and complete a comprehensive feasibility study to identify prime users, performance and integration requirements, and sustainment/cost tradeoffs to ensure a successful technology transition to the warfighter. ISIs integrated system provides the ability to perform weather monitoring operations both autonomously and with forecaster-in-the-loop capabilities in a very small SWAP-C format compared to the legacy tactical weather equipment. By building on the success of ISIs Micro Weather Sensor, which is already a DoD program of record, the risk of the MaWS development and transition is substantially reduced. By the completion of Phase I, ISI will prepare a fully integrated solution demonstrating the path toward achieving BAO and USAF requirements. During the Phase II, ISI will increase the maturity level of the MaWS system to a TRL-7/8 ready for comprehensive user field testing to validate greater capabilities than the aging AN/TMQ-53 system.Macro Weather Sensor,Weather Sensing,Weather Data Integration
