The Sun Tracker is one of the reasons today's cruise missiles can fly accurately. [11] Other research using the Sun Tracker technology yielded a substantial amount of data on the general makeup of the upper atmosphere, which was beneficial for many different types of applications such as space travel, and improvements in nuclear fission.
A solar tracker is a device that orients a payload toward the Sun. Payloads are usually solar panels, parabolic troughs, Fresnel reflectors, lenses, or the mirrors of a heliostat. For flat-panel photovoltaic systems, trackers are used to minimize the angle of incidence between the incoming sunlight and a photovoltaic panel, sometimes known as ...
A heliostat (from helios, the Greek word for sun, and stat, as in stationary) is a device that includes a mirror, usually a plane mirror, which turns so as to keep reflecting sunlight toward a predetermined target, compensating for the Sun's apparent motions in the sky. The target may be a physical object, distant from the heliostat, or a ...
Infrared homing is a passive weapon guidance system which uses the infrared (IR) light emission from a target to track and follow it seamlessly. [1] Missiles which use infrared seeking are often referred to as "heat-seekers" since infrared is radiated strongly by hot bodies. Many objects such as people, vehicle engines and aircraft generate and ...
A Sun sensor is a navigational instrument used by spacecraft to detect the position of the Sun. [1][2] Sun sensors are used for attitude control, solar array pointing, gyro updating, and fail-safe recovery. [3][4] In addition to spacecraft, Sun sensors find use in ground-based weather stations and Sun-tracking systems, and aerial vehicles ...
J002E3 is an object in space which is thought to be the S-IVB third stage of the Apollo 12 Saturn V rocket. It was discovered on September 3, 2002, by amateur astronomer Bill Yeung. Initially thought to be an asteroid, it has since been tentatively identified as the third stage of Apollo 12 Saturn V based on spectrographic evidence consistent ...
Mueller whole sky camera (ca. 1905) modified by Fassig. Reported in the 1915 issue of Monthly Weather Review. A whole sky camera is a specialized camera used in meteorology and astronomy for capturing a photograph of the entire sky. Another application is that of hemispherical photography to study plant canopy geometry and to calculate near ...
Sunseeker (solar vehicle) Sunseeker (front) at a midday stop in Sunrayce 1995. The Sunseeker Solar Car Project, Sunseeker for short, is Western Michigan University 's solar car team. Each vehicle is designed, built, maintained, and raced by students. Sunseeker has competed in all of the American Solar Challenge events, going back to 1990.
