PreviSat (may be the successor of TLE Analyser) is a free, open-source and multi-functional satellite real-time tracking software for Windows, Mac and Linux platforms, developed by astropedia from France. By analyzing the Two-Line Element (TLE) data published and updated regularly by United States Space Surveillance Network (SSN), it can achieve accurate prediction and tracking of satellite orbit, and simultaneously analyze the TLE parameters of hundreds of in-orbit targets.

PreviSat can display the position and trajectory of the satellites on a world map or sky map (for selected observation points), enabling users to see the position of satellite in a variety of coordinate systems. It has two modes of operation: real-time mode and manual mode, the latter can display the location of satellite of any date. In addition, it also provides many options for customizing the display of graphical interface elements, and allows to group the most commonly used observation points.

PreviSat is able to help user mark the coordinates of artificial satellites in real time, and calculate the orbit of satellites through its powerful AI computing technology, so as to meet users’ needs for tracking and management of artificial satellites. At the same time, it can also help users collect the location info of the sun and moon, so as to meet the diversified needs of astronomy enthusiasts.
