Sensis Corporation has been selected by the Air Navigation Service Provider (ANSP), Avinor to provide an Automatic Dependent Surveillance – Broadcast (ADS-B) system for enhancing helicopter traffic safety in the Norwegian area of the North Sea.
The ADS-B system will provide accurate identification and precise location of helicopter flights serving the oil and gas platforms during the day and night times.
Avinor's Modified – Automatic Dependent Surveillance and partial radar coverage are currently being used in the Ekofisk airspace, which handles more than 160,000 annual helicopter passengers from the Stavanger Airport. The surveillance system uses a geostationary satellite communications link and GPS to provide flight alerting and information services.
The Sensis ADS-B deployment will upgrade the airspace and enable it to support Air Traffic Control Service with a five nautical mile separation. The system will feature several ground stations formed at onshore and offshore installations.
Sensis ADS-B transceivers provide transponder multilateration, which allows independent assessment of the ADS-B system data. The broadcast system meets all ED-129 requirements and provides ASTERIX CAT21 output.
