Typically, a courier provides their courier service on a commercial contract basis; however, some couriers are government or state agency employees (for example: a diplomatic courier). Duties and functions. [edit] Couriers are distinguished from ordinary mailservices by features such as speed, security, tracking, signature, specialization and ...
Gas-diffusion electrocrystallization ( GDEx) is an electrochemical process consisting on the reactive precipitation of metal ions in solution (or dispersion) with intermediaries produced by the electrochemical reduction of gases (such as oxygen ), at gas diffusion electrodes. [1] [2] [3] It can serve for the recovery of metals or metalloids ...
The United States Space Surveillance Network (SSN) detects, tracks, catalogs and identifies artificial objects orbiting Earth, e.g. active/inactive satellites, spent rocket bodies, or fragmentation debris. The system is the responsibility of United States Space Command and operated by the United States Space Force and its functions are:
The shelter is used by the Marines of the 3rd Remotely Piloted Vehicle (RPV) Platoon to track their Pioneer RPVs during flight. A tracking system, also known as a locating system, is used for the observing of persons or objects on the move and supplying a timely ordered sequence of location data for further processing.
However, since humans reflect far less radar energy than metal does, these systems require sophisticated technology to isolate human targets and moreover to process any sort of detailed image. Through-the-wall radars can be made with Ultra Wideband impulse radar, micro- Doppler radar , and synthetic aperture radar (SAR).
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] Satellite tracking devices may send ...
Infrared search and track. An IRST sensor on a Sukhoi Su-35. An infrared search and track ( IRST) system (sometimes known as infrared sighting and tracking) is a method for detecting and tracking objects which give off infrared radiation, such as the infrared signatures of jet aircraft and helicopters.

Blue force tracking (BFT) systems consist of a computer, used to display location information, a satellite terminal and satellite antenna, used to transmit location and other military data, a Global Positioning System receiver (to determine its own position), command-and-control software (to send and receive orders, and many other battlefield support functions), and mapping software, usually ...
