Satellite positions are worked out with the reference SGP4 and SDP4 orbit models, checked against the published verification set and against NASA JPL's own track of the ISS. Geostationary and high orbits such as QO-100 and the GOES weather satellites get the full deep-space treatment.
AOS and LOS are solved to the second, a pass already under way shows its true start time, and Doppler correction uses the exact range rate at every moment of the pass. Orbital elements are read at full precision straight from CelesTrak.

About PhosphorBeam
PhosphorBeam is a real-time amateur radio satellite tracker built for operators who work the birds. Track passes, compute Doppler corrections, and plan contacts — all through a retro phosphor terminal interface.
REAL-TIME 3D GLOBE
A rotating 3D globe displays your favourited satellites with radio footprint coverage circles. Drag to rotate, pinch to zoom, double-tap to snap back to your ground station. Fly to any tracked satellite with the GOTO control. Geostationary birds like QO-100 are shown with distinct footprints.
PASS PREDICTION
Accurate SGP4 orbital propagation predicts upcoming passes for all your favourited satellites. Configure the prediction window (12, 24, or 48 hours), set minimum elevation thresholds, and optionally include NOAA APT weather satellites. Each pass shows AOS/LOS times, maximum elevation, azimuth sweep, duration, and a quality rating so you can prioritise the best contacts.
DOPPLER CORRECTION
Tap any predicted pass for a detailed view with sky track polar plot and Doppler frequency curves. Separate RX and TX plots are auto-scaled to show the kHz shift clearly. The AOS-to-LOS corrected frequency range is displayed above each plot so you know exactly where to tune before the satellite rises. During active passes, real-time corrected frequencies, range, azimuth, and elevation update every second.
COMPREHENSIVE SATELLITE DATABASE
Ships with a curated database of popular amateur satellites including FM repeaters (SO-50, ISS, TEVEL constellation), linear transponders (RS-44, AO-73, FO-29, AO-7), digital repeaters, and geostationary transponders. The database automatically expands by fetching active transponder data from AMSAT and orbital elements from CelesTrak. Browse, search, and filter by transponder type — FM, SSB, digital, or receive-only.
DETAILED ORBITAL DATA
Every satellite with orbital elements displays comprehensive information: altitude, orbital velocity, apogee, perigee, inclination, period, passes per day, revolution count, eccentricity, BSTAR drag coefficient, and TLE epoch. International designator and NORAD catalogue number identify each bird.
OFFLINE FIRST
Bundled orbital elements for key satellites mean the globe and pass predictions work immediately on first launch, even without network connectivity. Once online, TLEs refresh automatically from CelesTrak every 12 hours and transponder data from AMSAT every 24 hours. Any satellites still missing orbital data are individually fetched and cached.
CRT PHOSPHOR AESTHETIC
The entire interface is rendered in a retro terminal style inspired by classic phosphor displays. Choose between green and amber phosphor themes. Adjustable CRT scanline intensity. Monospaced typography throughout. It looks like something you'd find in a Cold War tracking station, because why shouldn't it.
FEATURES
Real-time 3D globe with satellite footprints and ground station marker
SGP4 pass prediction with configurable parameters
Doppler-corrected frequency plots with AOS→LOS tuning
