Power/Voltage-curve of a partially shaded PV system, with marked local and global MPP. Maximum power point tracking (MPPT), [1] [2] or sometimes just power point tracking (PPT), [3] [4] is a technique used with variable power sources to maximize energy extraction as conditions vary. [5]
A GPS tracking unit, geotracking unit, satellite tracking unit, or simply tracker is a navigation device normally on a vehicle, asset, person or animal that uses satellite navigation to determine its movement and determine its WGS84 UTM geographic position (geotracking) to determine its location. [1]
Early uses included the Nike Ajax missile, which demanded very high accuracy, or for tracking radars used for measuring various rocket launches. The world's first airborne monopulse radar system was the British Ferranti-designed AIRPASS system which went into service in 1960 on the RAF's English Electric Lightning interceptor aircraft.
Real-time locating systems (RTLS), also known as real-time tracking systems, are used to automatically identify and track the location of objects or people in real time, usually within a building or other contained area.
The effective collection area of a flat-panel solar collector varies with the cosine of the misalignment of the panel with the Sun.. Sunlight has two components: the "direct beam" that carries about 90% of the solar energy [6] [7] and the "diffuse sunlight" that carries the remainder – the diffuse portion is the blue sky on a clear day, and is a larger proportion of the total on cloudy days.
GPS animal tracking is a process whereby biologists, scientific researchers, or conservation agencies can remotely observe relatively fine-scale movement or migratory patterns in a free-ranging wild animal using the Global Positioning System (GPS) and optional environmental sensors or automated data-retrieval technologies such as Argos ...
Application of tracking is a substantial basis for vehicle tracking in fleet management, asset management, individual navigation, social networking, or mobile resource management and more. Company, group or individual interests can benefit from more than one of the offered technologies depending on the context.
GPS aircraft tracking is a means of tracking the position of an aircraft fitted with a satellite navigation device.By communication with navigation satellites, detailed real-time data on flight variables can be passed to a server on the ground.
