ESA cryosat vs Celestia

CryoSat is ESA’s (European Space Agency) first ice mission. Launched in April 2010, it provides multi-year elevation data at latitudes never reached before by a satellite altimeter. The satellite has sophisticated technologies to determine variations in the thickness of polar sea ice to monitor changes in the vast ice sheets that overlie Greenland and Antarctica. This application is a gateway to knowing what the mission is about, how it works and what the elements of the space and ground segment that makes this mission unique are. It includes also a dedicated section that allows one to discover and visualize real CryoSat measurements over our planet: a remarkable tool for students and scientists engaged in using CryoSat products or interested in satellite engineering. Features: - Description of the CryoSat mission: space and ground segment - Large selection of photos and videos on a wide range of topics related to CryoSat - Latest mission operations news - Striking CryoSat 3D model with explanations of the different platform and payload elements - World map with orbit position of the satellite - Satellite visibility over selected ground stations and local position - Automatic update of the CryoSat orbit - Impressive visualization of real Cryosat measurements over the Earth with vertical profiles and easy geographical localization - Access to several geophysical parameters measured by the satellite …and much more Continued use of GPS running in the background can dramatically decrease battery life. In the 3D environment: - swipe/pinch to rotate/zoom the satellite model - triple touch to reset position

Celestia — real-time 3D visualization of space 3D Space Simulator | Celestia lets you explore our universe in three dimensions. Celestia simulates many different types of celestial objects. From planets and moons to star clusters and galaxies, you can visit every object in the expandable database and view it from any point in space and time. The position and movement of solar system objects is calculated accurately in real time at any rate desired. Interactive Planetarium | Celestia serves as a planetarium – for an observer on any celestial object. You can easily navigate to any world and land on its surface. When used as a planetarium, Celestia shows accurate positions of solar system objects in the sky. You can switch labels and other supporting features on and off with hotkeys, or zoom in and out on an object of interest, for example Jupiter’s system of moons. Expandable Content | Customize Celestia according to your needs. Celestia’s catalogues can be easily expanded. There are many different add-ons available containing new objects like comets or stars, high-resolution textures of Earth and other well mapped solar system bodies, as well as 3D models for asteroids and spacecraft on precise trajectories. Even fictional objects from well-known sci-fi franchises can be found. EULA(End User License Agreement): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
