The project's sponsor, the West and Rhode Riverkeeper, needed to identify and implement mitigation measures to improve water quality in the subestuary...
High Altitude Airships (HAA) provide affordable, long duration, loitering platforms for communication and surveillance in both military and civilian markets. HAAs offer a potentially lower cost alternative to current unmanned aerial vehicles (UAV) and satellites. The objective of the HAA is to loiter above a given point at flight level (FL) 650 for a one year period before descending back to base...
