Geometric albedo node of their orbit, and hence lie on the ecliptic. In practice, measurements at small nonzero phase angles are used to derive the parameters which characterize the directional reflectance properties for the body (Hapke parameters). The reflectance function described by these can then be extrapolated to zero phase angle to obtain an estimate of the geometric albedo. For very bright, solid, airless objects such as Saturn's moons Enceladus and Tethys, whose total reflectance (Bond albedo) is close to one, a strong opposition effect combines with the high Bond albedo to give them a geometric albedo above unity (1.4 in the
Javelin (surface-to-air missile) Javelin (surface-to-air missile) Javelin is a British man-portable surface-to-air missile, formerly used by the British Army and Canadian Army. It can be fired from the shoulder, or from a dedicated launcher known as Javelin LML: Lightweight Multiple Launcher. Capable of being vehicle mounted, the LML carries three rounds. It was replaced in front line British service by the Javelin S-15, sold commercially as the Starburst surface-to-air missile in 1993 (radio frequency guided Javelin was retained for some time thereafter for training purposes), and later by the Starstreak starting around 1997. The Javelin GL was hastily purchased by the Canadian Forces
