High Altitude Research Project (HARP) firings were conducted both at Wallops Island, Virginia and Barbados, West Indies during the months of June through October 1964. A substantial number of these firings included high-'g' telemetry experiments. Three telemetry payloads were flown at Wallops in June and July, and three more in October. During the month of July, thirteen telemetry vehicles were flown at Barbados. The telemetry experiments were highly successful. Five of the six payloads flown at Wallops functioned and four gave data. Nine of the thirteen units fired at Barbados survived the high-'g' launch. Seven of these successfully transmitted data. The results of measurement are presented and include sunseeker data, event monitoring, temperature data, and the performance of magnetometers and pressure gates.
