Satellite Tracker vs HamSat

Satellite Tracker is the follow on to our award winning HamSat series of applications. Satellite Tracker merges all the features of the iPhone and iPad versions providing you a single application that seamlessly optimizes the screen to the device you’re running it on (check out the various iPhone and iPad screen shots). The application will calculate the rise/set times and associated azimuth and elevation for the selected satellite, Sun or Moon given either the user entered or network retrieved location. There are two modes for satellite rise/set calculations. The first is for those folks wanting to know all overflights for a given location (like Ham radio operators) while the second mode computes only those passes where the satellite would be visible to a ground observer. In the ground observer mode, the calculations not only take into account that the ground is dark but also that the satellite is in sunlight (it even takes into account if the satellite becomes lit or unlit during the pass) In addition, you can see the Earth rendered either as a 3D globe or a 2D map using photo realistic texture maps for the Earth model. The orientation of the map is easily changed by a simple rotation of the device from portrait (3D) to landscape (2D). In either orientation you can zoom in and out as well as pan using the touch screen. There are more than a dozen controls provided to allow you to customize how the application works to meet your specific needs (type of Earth texture used, location, type of overflight calculated…) Finally, the application is now free to download and provides full functionality for tracking, viewing and communicating with the International Space Station (what was the capability of the ISS family of paid apps). The following subscriptions are available for tracking and communicating with a larger set of satellites: -HamSat (Annual and Monthly): Provides access to the NORAD and AMSAT two line element sets which cover all amateur related satellites. -ProSat (Annual and Monthly): Provides access to thousands of satellites grouped into the following categories (from www.celestrak.com): -100 (or so) Brightest -Last 30 Day’s Launches (or so) -Amateur Ham Radio Satellites -CubeSats -Disaster Monitoring -Earth Resources -Education -Engineering -Geodetic -Geostationary -GOES -GPS Operational -Intelsat -Iridium -Molniya -NOAA -Orbcomm -Search & Rescue (SARSAT) -Space & Earth Science -Space Station -Weather To get a feel for the apps, please checkout the iPad quickstart video (http://www.youtube.com/watch?v=tiHCGxV0WM8) and associated user’s guide (http://www.vosworx.com/wp-content/uploads/2017/05/SatSeriesHD.pdf) or the iPhone quickstart video (http://www.youtube.com/watch?v=iuPccQI9oSg) and it’s user’s guide (http://www.vosworx.com/wp-content/uploads/2017/05/SatSeries.pdf). Please note that InApp payments will be charged to your AppleID account at the confirmation of purchase. Subscriptions automatically renews unless it is canceled at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours prior to the end of the current period.

HamSat is the satellite tracker built for amateur radio operators — with an Apple Watch companion on your wrist and, new in 2.1, a sked planner that finds the passes you and another operator can work together. NEW — SKED PLANNER (Pro) • Plan a contact, not just a pass: enter another operator's grid square and find every window where a satellite sees you both • Set a minimum elevation for each end of the link — a window only counts if it's workable at both stations • One tap adds the sked to your calendar with the overlap times, a 10-minute reminder, and the radio setup PLAN AHEAD • Pass predictions up to 7 days out • Add any pass to Apple Calendar — times, reminder, and frequencies in the notes. HamSat never reads your calendar. • Choose your pass-alert tone — including a CW "HI" in Morse APPLE WATCH (Pro) • Your next favorite pass on your wrist: live azimuth, elevation, Doppler-corrected frequencies, and a countdown to AOS • Guided wrist-aim — follow an arrow straight to the satellite and feel a haptic tap the instant you're locked on. Aim your antenna without looking at a screen, hands free for the radio. • Propagated on the watch itself, so it keeps tracking even when your phone is out of range PASS TRACKING • Live sky dome with the satellite's arc and a glyph riding it in real time • Fullscreen Live tracker — big AZ/EL, Doppler-corrected frequencies, landscape split-pane • Aim mode uses your phone's compass to show where you're pointing — no forced figure-8 calibration, just point and go • Apple Maps ground track with horizon footprint OPERATING DURING A PASS • Doppler-corrected RX (and TX for SSB/linear) dial frequencies, updated every second • 10-minute and AOS notifications that deep-link straight to the pass • Live Activity + Dynamic Island on the lock screen, elevation and azimuth ticking live • Bell badge on any pass you've set an alert for ROVER PROOF PHOTOS • Stamp a photo at your site with your callsign, grid, satellite, and UTC time — proof of where you were on the air • Fresh photo or one from your library; share to X, Messages, AirDrop — or submit for the AMSAT Rover Award ALWAYS OVERHEAD (free) • Lists any geostationary satellite in your sky — QO-100 (Es'hail 2) for Europe, Africa, and the Middle East • "Find it in the sky" — point your phone and check your line-of-sight to the bird is clear • No Pro required for geostationary satellites SATELLITE CATALOG • Friendly designations everywhere — SO-50, AO-91, RS-44, JO-97 — with launch names as subtitles • Search by name or NORAD ID • Curated radio data for the most-worked birds, plus live SatNOGS for the long tail — kept fresh by HamSat's catalog service • Filter by mode (FM, linear, beacon, data, telemetry) ACCURATE & OFFLINE • Full SGP4 propagation on-device — the model the pros use, so times and positions match apps like ISS Detector • Works completely offline — every pass, sky dome, ground track, and Doppler computed locally. No API keys, no rate limits. • Always-fresh orbital data via HamSat's catalog service, with direct CelesTrak/AMSAT fallback — or pin a source • Settings shows how fresh your orbital data is PRIVACY-FIRST • Your location stays on-device — nothing about you is sent to any server • Orbital data from public sources (CelesTrak, AMSAT, SatNOGS) • No accounts, no tracking, no ads HamSat Pro — the field operator's toolkit • Sked planner — mutual passes with any partner grid • Apple Watch tracking & guided wrist-aim • Fullscreen Live tracker with second-by-second Doppler (landscape split-pane) • Live in-pass Doppler — corrected RX/TX at AOS, max, and LOS • Overhead-now live tracker for your favorites • Unlimited scheduled alerts — not just three • Shareable Rover proof photos One-time purchase, no subscription. 73 — and good DX!
