Satellite description
The satellite was 1.2 m in diameter, 2.3 m in height. It weighed 260 kg at launch.[7] The design was based on the military reconnaissance satellite Ofeq-3, which was previously built, also by Israel Aerospace Industries (IAI) for Israeli government use.

Following its launch, the first customer announced was the Ministry of Defense of Israel, which paid about $15 million for the exclusive rights to receive all images of Israel's territory and an area within a radius of about 2,000 km. The need for the satellite's capabilities was due to the failure of the launch of the Ofek-4 satellite, two years earlier and the decay of Ofek-3.[9][10] Other customers of the satellite were the Taiwan Defense Ministry,[11] India,[12] and media organizations that purchased footage from the battlefield at the start of the Afghan war, footage that competitor "Space Imaging" (Owner of Ikonos) was banned from selling by the US government.[13] Additionally, a database was established with photographs of the satellite that were sold to companies around the world on demand.[14]
The satellite increased its orbital altitude for the last time on 24 April 2012 and reentered on 7 July 2016.[1]
