Fajr (Persian: فجر‎, meaning "dawn") is an Iranian satellite which was launched in February 2015. An imaging satellite, Fajr also carries an experimental locally made GPS system.[citation needed] The satellite will have a life span of 1.5 years and an imaging resolution of 500 to 1,000 metres (1,600 to 3,300 ft). It is the first Iranian satellite to use cold gas thrusters for attitude control and is equipped with solar panels for power generation.

Fajr was launched by a Safir-1B rocket from the Iranian Space Agency's launch site in Semnan Province.[1][2] The launch took place at around 08:50 UTC on 2 February 2015, Iran's national day of space and the sixth anniversary of the country's first successful orbital launch. The satellite was deployed into a low Earth orbit.

On 26 February 2015 Fajr reentered earth's atmosphere after 23.8 days in orbit.[1] [3]
