OrbitDeck vs SSTV+

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.

SSTV+ is a Slow Scan Television audio encoder and decoder designed for amateur radio enthusiasts. Use your iPhone’s microphone to listen for SSTV audio signals. SSTV+ automatically detects the VIS mode and progressively reconstructs the image entirely on your device. You can also select a photo from your library, encode it as standard SSTV audio, play it through the device speaker, or export it as a WAV file. Key Features: • Receive and decode SSTV audio signals in real time • Automatically detect VIS modes • Encode photos as SSTV audio • Scale, fill, crop, and reposition images • Support Robot 36 and Robot 72 • Support Martin M1 and Martin M2 • Support Scottie S1 and Scottie S2 • Support PD 90, PD 120, and PD 180 • Keep a local history of received and transmitted images • Optionally retain original received audio • Export and share WAV audio files • Save decoded images to your Photos library Completely Offline: SSTV+ requires no account or sign-in and does not connect to any servers. Signal detection, image decoding, and audio generation are performed entirely on your device. The app contains no advertising, user tracking, analytics SDKs, or cloud synchronization. Your photos, audio, and history remain stored locally on your device. Nothing is uploaded to the developer or shared with third parties. All core features remain available without an internet connection. Permissions: • Microphone: Used only to receive and decode nearby SSTV audio signals • Photos: Used only when you choose a photo for encoding or save a decoded image SSTV+ only processes and plays audio. It does not directly transmit radio-frequency signals. When using the app with external radio equipment, please follow the amateur radio regulations applicable in your country or region.
