The Australian Defence Satellite Communications Station (ADSCS) is located at Kojarena, near Geraldton. The ADSCS is part of the US signals intelligence and analysis network ECHELON. The station has four satellite tracking dishes which intercept communications from Russian, Chinese, Japanese, Indian and Pakistani regional satellites[1] and international communications satellites (INTELSATs and COMSATs), throughout the Indian Ocean and South-East Asian regions. Staff are drawn from the American National Security Agency and the Australian Defence Signals Directorate, and the site is operated under the UKUSA Agreement
