A VHF electronic polarimeter for total electron content (TEC) measurements has been in operation at Troms0 Telemetry Station (69 deg 39'N, 18 deg 56'E) in Northern Norway for the period April 1980 to April 1981. The polarimeter has been receiving data from the geostationary satellite SIRIO, which is situated almost due south of Troms0 at 8 deg elevation. Except for loss of data during periods when the satellite was eclipsed by the Earth's shadow, continuous data coverage was maintained. Preliminary analysis of the obtained TEC data and similar data deduced from NAVSTAR-GPS measurements reveal acceptable agreement. (Author)
