Real-time locating system. 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. Wireless RTLS tags are attached to objects or worn by people, and in most RTLS, fixed reference ...
Uphere.Space real time tracking and predictions. As soon as new satellites are launched this application begins tracking them. ISS Tracker, since 2015 the most popular ISS Tracker and passes list. Heavens-Above, called "the most popular website for tracking satellites" in 2007 by Sky and Telescope magazine and referenced by NASA websites.
800 kilometres (500 mi) Inclination. 100.2ยบ. Period. 100.7 minutes. PicoSAT, launched on September 30, 2001, is a real time tracking satellite. The name "PICO" combines the first letters of all four of its experiments (see below). PICOSat series are designed for a minimum of one year of on-orbit operations.
The Baker-Nunn system, like Minitrack, provided little real-time data and was additionally limited to night-time, clear weather operations. [4] Beyond the problems in acquiring data on satellites, it became obvious that the US tracking network would soon be overwhelmed by the tremendous number of satellites that followed Sputnik and Vanguard.
