De gebeurtenissen aan de sterrenhemel in Nederland en België op je mobiel! SterHemel toont in een handomdraai wat er aan de sterrenhemel te zien is met het blote oog, een verrekijker of een kleine telescoop. De app is bedoeld voor waarnemers in Nederland en België en is daarom in het Nederlands/Vlaams gemaakt. De app toont de gebeurtenissen aan de sterrenhemel onder andere in de vorm van een astrokalender, de tab "Vannacht aan de hemel" met inforatie over Zon, Maan planeten en deepsky-objecten, een hemelkaart, een maanfasekalender, waarneemweer en meer. SterHemel is de app van hemel.waarnemen.com en net als de website is de app gratis en zonder reclame. De inhoud bestaat uit een selectie van de belangrijkste webpagina's van hemel.waarnemen.com, geoptimaliseerd voor het schermformaat van een telefoon. Voor een tablet geniet het gebruik van een webbrowser de voorkeur.

Wo ist Io ist eine Android Astronomie Anwendung, die Daten über Himmelskörper im Sonnensystem berechnet. Es bietet Auf- und Untergangs Visualisierungen und -Zeiten für alle Planeten und eine Spiral-Graph Ansicht der Jupitermonde für nächsten Tagen

Technological demo of OpenGL ES 2 for Android platform. It reads public NORAD satellite database and shows the satellite positions and altitude related to Earth in the form of beams (the height of the beam represents the relative altitude). NOTE: The project has been moved to GitHub: https://github.com/nuald/glSatellite-Demo The old one stays here just for the historical reasons. The 3D features present: - OpenGL ES 2; - rotating, multi-touch zooming and moving the globe; - stars on a fixed background; - each satellite is represented by a beam with a unique color; - identifying the corresponding satellite if a beam has been tapped (based on color picking method). Additionally to 3D features presented the application is: - using NDK with C++11 features compiled by LLVM clang; - mixing Java views with OpenGL views (Java is used for settings activity, information and ads panels); - using Android custom message queue to send asynchronous messages from Java to JNI
