The Johns Hopkins University Applied Physics Laboratory has developed a small, lightweight transmitter to track the positions of migratory birds by satellite. Solar-powered prototype units weighing less than 170 grams have been built and used to position free-flying birds. Future plans include the development of smaller, lighter units having microprocessor-based environmental sensors.
