Introduction
A geostationary (Earth) satellite is a satellite that rotates around Earth in a certain orbit such that it is always positioned above the same point on the Earth’s surface. Hence from the point of view of an observer standing at that point, the geostationary satellite appears to be always ‘stationary’ above him/her (but actually, both observer and satellite are rotating at the same angular speed). In order for a satellite to be moving in such a geostationary orbit, there are certain conditions to meet:
placed vertically above the equator
same directional sense as the rotation of the Earth (determine through axis of rotation)
same orbital period of Planet, in our case, Earth, thus the orbital period of approximately 24 hrs
The simulation has a Earth and a Satellite object Menu Drop Down Allows for selecting what motion of Satellite is simulated.
Geostationary near Singapore
Geostationary near Africa
Geostationary near America
Non-geostationary due to direction
circular motion r=3*Re, T =7.30 hr
circular motion r=10.5*Re, T = 48 hr
Non-Geostationary generally
Unlikely Orbits
Options added are:
Show:equator Plane, for visualising the Earth's rotating equator plane
Geo stationary, for visualising a geostationary object (RED) for comparative observation with the other modes.
Show text: 35 700 km fixed position of object relative to planet earth.
Axes earth: show spin axes of the rotation of earth in GREEN
Axes satellite: show spin axes of the rotation of satellite in MAGENTA
Force: pair of action reaction force of equal magnitude, opposite direction and on different bodies. (Newton's 3rd Law)

Questions & Answers
Q: What is an APK File?
A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.
Q: If I install an APK from this website, will I be able to update the app from the Play Store?
A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.net goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.
Q: Why ApkClean.net can guarantee APK 100% safe?
A: Whenever someone wants to download an APK file from ApkClean.net, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.
Q: What are Android App permissions?
A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.
Don't hesitate to contact us if you have any questions or concerns.
