It is equipped with a SYERS 2A sensor.[6] ORS-1 satellite is designed to provide orbital space imagery of Southwest Asia and to enhance battlespace awareness to operational field commanders. The ORS-1 will undergo a 30-day trial and adjustment check before the ORS Office turns over it operations to USAF’s 1st Space Operations Squadron at Schriever AFB, Colorado.[2] SYERSSYERS 2 is an optical and infrared camera with a 40 cm aperature and a field of view larger than 2 degrees. It uses Time Delay and Integration CCD sensors to compensate for ground motion, resulting in a resolution of 1m (NIIRS 4) from a nominal 300 km orbit.[7] SYERS 2 is supplied by the Goodrich Corporation. SYERS is also carried by the Lockheed U-2 reconnaissance aircraft.[8] See also{{Portal|Spaceflight}}
