Geoscience Australia's predictive schedules for public good satellites over Australia
Background
Every day more than a dozen foreign-operated, public-good, non-commercial, medium to low resolution satellites fly over Australia and its territories. They cross the continent several times a day and their sensors capture images of the landand coastal waters.
Satellite overpass schedules for each spacecraft are predictable and can be calculated with a degree of accuracy. The Daily SatPaths provides information on which satellite sensors have and will potentially acquire data over Australia during a given date and time interval. It is important to note that actual acquisition schedules may differ from those presented in Daily SatPaths due the operational limitations of the satellite.

What this product offers
Daily SatPaths calculates date-specific predicted schedules for flyovers over Australia for 19 of the most popular public good satellites used by researchers in academia, and by public and private sector organisations.
It also displays, on an interactive map, the portion of Australia that is “visible” to those satellite sensors on each flyover (i.e. the so-called “ground footprint”).
The flight path schedules and sensor specific footprints can be downloaded in a tabular format (.csv file) and polygons in GeoJSON format for use in GIS software.

- Statement
-
Information on start and end times for satellite flyovers, as well as position of satellites at a given time, are generated in real-time in the user browser based on current day two-line element set (TLE) data from SpaceTrack.org and jspredict library with algorithms ported from Predict open source tracking and orbital prediction software ( https://www.qsl.net/kd2bd/predict.html).
Ground footprint information is generated based on published, sensor specific swath widths, using general purpose ellipsoidal geometry spatial libraries latlon-ellipsoidal.js and latlon-vincenty.js
