The company says its sub-metre Kuanfu 02B series can cover large and medium-sized cities – such as Beijing and Taipei, for example – in a single pass, eliminating the need for multi-orbit stitching and enabling fast, large-scale monitoring. The high-definition imagery achieved by the satellite’s 0.5m (1ft 7.
7in) resolution supports multispectral fusion, allowing for precise identification of surface features across a swathe of 150km (93.2 miles). This makes the Kuanfu 02B 10 times more efficient than its competitors, which typically have swathes of 5-20km, giving it the capacity to cover more than 2 million square kilometres (0.
77 million square miles) in a day. At the same time, the weight of the new satellite has been slashed from the hefty 1,200kg (2,650lbs) of its predecessor Kuanfu 01 to just 230kg, making it the lightest of its kind on the market, and drastically cutting production and launch costs. Chief engineer Zhang Lei said that one of the company’s main challenges since its founding 11 years ago had been to produce satellites with high specifications while keeping costs, weight, and power consumption low.
