Welcome to Star Trek Answers. What would you like to know?

Short-range sensors (typically located in the rim of the hull as well as upper and lower sensor platforms) consist of astronomical and planetary sensor arrays that can give detailed information on planetary bodies or astronomical phenomena at a distance of one light-year. Additionally, the long-range sensors (normally located behind the ship's navigational defector dish) have three resolutions: low, medium, and high. In low resolution, they scan at distances over 17 light-years. In medium resolution, they scan distances from 10 to 17 light-years. At this range, the sensor beam (traveling at warp 9.9997) takes approximately 45 minutes to reach its destination and another 45 minutes to return. In high resolution, the long-range sensors scan at a maxium distance of 5 light-years. Within the confines of a solar system, the long-range scanners in high resolution mode can give instantaneous information. However, they are not designed to give as detailed a scan as the short-range planetary arrays. If, for some reason, the ship could not get close enough to use the short-range sensors, most starships carry a wide assortment of probes. Admiral William Thomas Riker 02:26, October 16, 2011 (UTC)
