An Aerostat/Elevated Antenna Component to Aid VHF Radiotelemetry and Tracking of Right Whales in Critical Habitats

Abstract

Elevating the receiving antenna in projects to monitor movements and behaviors of right whales, Eubalaena glacialis, in critical habitats will increase range and efficacy. This was accomplished by mounting the antenna and receiver on an aerostat (tethered balloon). At altitudes of 200 ft or greater, ranges of 15-20 miles can be expected. This project evolved to include other applications, and demonstrated the use of aerostats for carrying antenna arrays, instrument packages, sensors, and cameras to altitudes of several thousand feet. An emerging area in the field of environmental technology has been identified.
