Anik B1

NSSDCA/COSPAR ID: 1978-116A

Description

Anik B was launched from Cape Canaveral aboard a Thor Delta vehicle. As of February 1979, the spacecraft was successfully placed into a geostationary orbit. The 14/12 GHz transponder system was tested and performed satisfactorily. In April 1979, continuous service to DOC was provided, at which time pilot project activity began. In total, nineteen projects were undertaken. In 1980, the department leased one of the channels back to Telesat, who then re-leased it to La SETTE. The channel was used by La SETTE to distribute videotaped programming from France to cable stations in Quebec. This was the world's first commercial service in the 14/12 GHz band.

Several concepts that were introduced with the Hermes experiments were demonstrated to be operationally feasible during the Anik B trials and were continued on to commercial operation. These included the delivery of TV Ontario educational programming throughout Ontario by satellite; the formation and operation of the Knowledge Network, and educational channel in British Columbia; and the formation of the Inuit Broadcasting Corporation. Other services such as a tele-health network in Newfoundland and tele- conferencing for the Government of Ontario, tried first by satellite, were continued via terrestrial facilities.

There were severl important outcomes of the Hermes and Anik B programs. The concept of satellite communications was revolutionized by the very small earth stations that could easily be erected almost anywhere without being constrained by interference to sites far from cities. In particular, the small TVROs proved the concept of DBS to be technically feasible and less power was required from the satellites than had been originally expected. Of the Anik B projects, the one with the widest impact was the direct broadcasting service to remote areas. For these projects, the DOC purchased one hundred low-cost receivers from SED Systems of Saskatoon, half for use in British Columbia, the Yukon and Northwest Territories, and half for Ontario. The results were encouraging. By the end of the Anik B program, sufficient data had been gathered to allow the user organizations to decide whether or not satellite (or telecommunications) systems were a useful and desirable vehicle to provide services on a long-term basis.

With a de4sign life set to end November 1985, Anik B was decommissioned in 1986.
