Smart Planetarium Reference
by: Klaus Becker





Description
Smart Planetarium is an astronomy app for Symbian smartphones which has almost the same capabilities as Google-Skymap. It shows all stars up to a magnitude of 5.0 and the positions of the sun, the moon and the planets. If you switch on the GPS and step up to a star, the app will show the sky in that direction. If you hold the screen of the smartphone against the sky, the acceleration sensors in the phone will position the star in the midst of the display.- $ 1.99

Gauss-Krueger to UTM Reference
by: Klaus Becker





Description
This program calculates UTM-Coordinates based on the GRS80-Ellipsoide (ETRS89) from Gauss-Krueger-Coordinates base on the Bessel 1841-Ellipsoide (DHDN). For the calculation it uses a combination of Helmert-Transform and a modification of BeTA2007. The goal is to have a good transfomation that also works in the mountains. The calculation is conform with all 31 test data from BeTA2007 within a precision of 0.5mm.- $ 2.99
