An Australian company has acquired imaging technology used on NASA's deep space probes to Mars to develop a $275 million high-resolution, full-colour satellite imaging system capable of identifying a 10-metre fishing boat lurking in the north Australian mangroves from an altitude of 36,000 kilometres. Astrovision Australia, a 51 per cent-owned subsidiary of listed technology company Horizon Global, is developing the system, which will provide emergency and defence imaging and high bandwidth video services to mobile phone carriers.
