This article contains orbital elements but does not include an epoch, or date when those elements, which typically vary over time, were correct. Please help by adding the epoch for the current data, or changing the orbital elements to ones with a known epoch. |

USA-231,[3] formerly ORS-1 (Operationally Responsive Space) is an American reconnaissance satellite which was launched in 2011 from NASA’s Wallops Flight Facility, Virginia by a Minotaur I launch vehicle.[1] It is the first operational satellite of the Operationally Responsive Space Office. It is equipped with a Senior Year Electro-Optical Reconnaissance System (SYERS) 2A.[4]
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.[1]

SYERS functions[]
SYERS 2 is a optical and infrared camera with a 40 cm aperature and a field of view larger than 2 degree. 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.[5] SYERS 2 is supplied by the Goodrich Corporation.
SYERS previous version has also been used with the Lockheed U-2 reconnaissance aircraft.[6]
