Abstract
Describes the development of a baseline system architecture designed to meet the basic requirements of an all-terrestrial backup communications system linking the Canadian North Warning System radar sites with the Regional Operations Control Centre. The system, which includes sufficient capacity to carry all radar data and several digital voice channels, consists of approximately 100 low-power T1 UHF digital repeater located at each radar site and one or more bent-pipe repeaters between radars as required. The system is designed for low primary power consumption and installation using light helicopters only. An experimental UHF digital radio system was designed and built to demonstrate the baseline system architecture. The system, installed and operated in the western arctic, links two radar sites with the terrestrial telephone system at Inuvik. The system features full duplex data transmision at 256 kb/s with data insertion and retrieval at any repeater, measurement of received signal strength and system status at each repeater, data acquisition and storage at Inuvik for subsequent retrieval using the terrestrial telephone system, and a unique, efficient power supply system incorporating solar panels, lead-acid storage battery, backup primary battery and controller. Primary power consumption of a bent-pipe repeater is less tham 3 Watts. TRUNCATED.
