OrbitDeck vs CloudSatellite

OrbitDeck is a complete amateur-radio satellite station for iPhone and iPad. Track the birds, predict passes, tune your radio for Doppler, decode images, and log your contacts — all from live orbital elements. TRACK & PREDICT • Live look angles, range, range-rate, sub-point, and footprint • Next-pass predictions with quality scoring and elevation profiles • Daily schedule of every favorite's passes, ordered by AOS • Ground-track map, multi-day pass progression, and an all-sky radar • Animated 3D globe and a polar sky plot with AOS/LOS and direction-of-travel arrows WORK THE BIRDS • Four-dial Doppler for DX plus a single-station playbook • Per-satellite calibration shared across every Doppler screen • Link budgets, SatNOGS transponder data, AO-7 mode timer, and mutual-visibility windows RIG CONTROL (CAT) • Doppler-tune your transceiver over a Bluetooth serial adapter or an Icom network (Wi-Fi) radio • Icom CI-V, Yaesu, Kenwood (including TS-2000/790 satellite mode), and any Hamlib radio via rigctld • One full-duplex radio, a separate uplink/downlink pair, or two radios; follows your dial as you tune ROTATOR CONTROL • Azimuth/elevation control via GS-232, Easycomm, SPID, rotctld, PstRotator, SAEBRTrack, and OZ9AAR URC DIGITAL MODES & AUDIO • Over a USB audio interface or Icom network audio: record a pass, decode SSTV (Doppler-aware, with a post-pass re-decode and image fix-up), and work full-duplex FT4 on a linear transponder LOGGING • On-device QSO log with ADIF export and LoTW and Cloudlog/Wavelog upload Plus orbital analysis, live space weather, MUF/propagation, and classic OSCARLOCATOR overlays. OrbitDeck works fully as a tracker with no radio and no account. Rig control, rotator control, SSTV, and FT4 require your own amateur-radio equipment and a valid license; transmit only within your privileges. Orbital elements from AMSAT and CelesTrak; transponder data from SatNOGS; space weather from NOAA SWPC. FT4/FT8 use the MIT-licensed ft8_lib.

CloudSatellite brings satellite pass predictions, live tracking, antenna rotator control, radio frequency coordination and audio decoding together for satellite observers and amateur radio operators. SATELLITE LOOKUP AND PASS PREDICTIONS Find satellites by name or NORAD ID and view orbital information and amateur radio frequencies. Predict pass times, duration, azimuth and maximum elevation for your observing location. LIVE POSITIONS AND TRACKING Use the orbit map and sky view to follow satellite positions, paths and directions relative to your location. ROTATOR AND RADIO CONTROL Connect compatible antenna rotators, amateur radio transceivers or SDR devices for manual control and automatic tracking. Coordinate uplink and downlink frequencies and compensate for Doppler shift as the satellite moves. NEW: CUSTOM EPHEMERIS Import TLE and OMM JSON orbital data and manage custom ephemeris for satellite lookup, position calculations and tracking plans. NEW: SSDV AUDIO DECODING Receive live audio or process audio files to decode supported SSDV signals and reconstruct images for viewing and further processing. AUDIO AND SIGNAL TOOLS On supported devices and connections, view audio spectra and waterfall displays, record audio, and send, receive and manage SSTV images. PERSONAL SETTINGS Save favorite satellites and customize observing locations and prediction ranges. Available in Simplified Chinese, English, Japanese, Spanish, German, Brazilian Portuguese, Russian and French. Equipment control and audio features require compatible hardware and connection settings. Availability depends on the device and platform.
