The TLE format is a de facto standard for distribution of an Earth-orbiting object's orbital elements. A TLE set may include a title line preceding the element data, so each listing may take up three lines in the file, in which case the TLE is referred to as a three-line element set (3LE), instead of a two-line element set (2LE). The title is ...
Offline since April 2010, replaced by NASA Skywatch web application. [4] NASA Skywatch, Java based web application. Predicts visible passes for spacecraft, satellites and space debris. [5] AMSAT Online Satellite Pass Predictions. N2YO provides real time tracking and pass predictions with orbital paths and footprints overlaid on Google Maps. [6]
Systems Tool Kit (formerly Satellite Tool Kit), often referred to by its initials STK, is a multi-physics software application from Analytical Graphics, Inc. (an Ansys company) that enables engineers and scientists to perform complex analyses of ground, sea, air, and space platforms, and to share results in one integrated environment. [1]
Single-pass collection of mosaics (strip-mapping) with a footprint up to a square degree Maximum theoretical acquisition capacity of 1,000,000 km 2 per day and per satellite Optimized daily acquisition capacity (taking into account genuine order book, weather constraints, conflicts...) reaching 300,000 km 2 per day and per satellite
FreeFlyer has been used to support many spacecraft missions, for mission planning analysis, operational analysis, or both. Specific mission examples include the International Space Station (ISS), [7] the JSpOC Mission System, [8] the Earth Observing System, [9] [10] Solar Dynamics Observatory (SDO), [11] and Magnetospheric Multiscale Mission (MMS).

For orbit propagation purposes, there is a field for BSTAR drag in two-line element set (TLE) files, where it is to be given in units of inverse Earth radii. [2] The corresponding reference air density is given as 0.15696615 kg / ( m 2 ⋅ R Earth ) {\displaystyle 0.15696615{\text{ kg}}/(\mathrm {m} ^{2}\cdot R_{\text{Earth}})} . [ 3 ]
