SKY SPOTTER is a passive EO early warning system with a high probability of detection and a very low false alarm rate. The system tracks multiple targets simultaneously with a 24/7 persistent capability. The use of highly sensitive MWIR, SWIR and day sensors – as well as WFOV and NFOV multispectral sensors – allows detailed investigation of selected targets. Advanced algorithms of automation, image processing, and Artificial Intelligence (AI) enable multiple targets to be detected, tracked and managed simultaneously.
