OrbitSmith vs CALINT Satellite View

OrbitSmith is a free, open-source space situational awareness toolkit that puts the orbital environment at your fingertips. REAL-TIME 3D TRACKER Visualize 30,000+ objects orbiting Earth — active satellites, rocket bodies, and debris — rendered in real-time 3D with Blue Marble Earth textures. Tap any object to see its orbital details, search by name or NORAD ID, and track conjunction events from Space-Track CDM data. VISIBLE PASS PREDICTIONS Know exactly when to look up. OrbitSmith predicts visible passes of ISS, Tiangong, Starlink, and hundreds of bright satellites using SGP4 orbital propagation with real TLE data. Interactive sky charts with 44 reference stars help you find the satellite in the sky. NOTIFICATIONS & WIDGETS Never miss a bright pass. Receive push notifications before ISS and other satellites become visible, and check your next pass at a glance with lock screen and home screen widgets. MISSION DESIGNER Design satellite missions with a 5-step wizard. Choose from 7 mission templates, configure orbital parameters, run power/link/thermal/mass/orbit decay analysis, and find compatible launch vehicles from a database of 10 rockets. SATELLITE IMAGERY Browse 21 layers of satellite imagery from NASA, ESA, and ESRI — including MODIS true color, VIIRS night lights, sea surface temperature, vegetation health, and Sentinel-2 cloudless. All orbital data sourced from the U.S. Space Force via Space-Track.org.

CALINT Satellite View is an application for visualizing information about GNSS (Global Navigation Satellite System) satellites. Based on your current location, the app provides an intuitive view of where positioning satellites are located in the sky. It also helps users better understand satellite positioning systems, including Japan's Quasi-Zenith Satellite System (QZSS), known as Michibiki. Key Features: • Display GNSS satellite information • Visualize satellite positions • View satellite information on a map • Filter displayed satellites • Explore satellite positions at different times CALINT Satellite View is designed for anyone interested in satellite positioning, GNSS, and location-based technologies. CALINT is a series of applications designed to make location-based technologies more accessible, understandable, and useful.
