Copernicus Sentinel vs Satellite Chasers

The Sentinel App is a gateway to knowing the Copernicus Sentinel satellites. It lets users track the satellites in real-time, discover their key elements, read the latest news and learn more about their products. Users can, among other things, explore detailed 3D models of the satellites, see the last and next time they have been and will be over the user's location, move the satellites to the time of the last data transmission and smoothly move them back to their current location over the 3D globe. Notifications can also be set to be warned when the satellites are flying by. ESA is developing a series of next-generation Earth observation missions, on behalf of the joint ESA/European Commission initiative Copernicus (previously GMES - Global Monitoring for Environment and Security). The goal of the program is to replace current and older Earth observation missions, such as ERS and Envisat, which have reached or are close to reaching the end of their operational life span. This will ensure a continuity of data so that there are no gaps in ongoing studies. Each mission will focus on a different aspect of Earth observation, such as Atmospheric, Oceanic or Land monitoring, and the data will be of use in many applications.

Satellite Chasers lets you explore the real satellite catalog from your phone, including active satellites, rocket bodies, debris, and newly added objects soon after launch. Point your phone at the sky in AR to see what is overhead, or explore satellites over the globe. Track satellites, launches, predicted decays, and conjunctions, which are close approaches between objects in orbit that may indicate potential collision risk. Features include: - Track tens of thousands of objects cataloged in Earth orbit - Use AR to see satellites overhead through your phone’s camera - Play SatSpot, a satellite pointing challenge where your aim determines your check-in points - Get notifications for predicted decays, conjunctions, launches, and newly added satellites - Search launches and see what flew together - Read space news connected to satellites, launches, and orbital activity - View satellite images, descriptions, radio/transmitter data from SatNOGS, and select NASA 3D models - Customize filters to show the satellites you care about - Check in with nearby satellites, earn points, and compete on leaderboards - Favorite satellites and organize your personal Orbit of friends Whether you are a space nerd, ham radio operator, sky watcher, or just curious about what is passing overhead, Satellite Chasers gives you a playful way to explore orbit in real time.
