Eclipse season prediction and daily sun-transit outage windows for the Indonesian GEO fleet, with a live status panel and editable satellite list.
Open tool →Sun Outage Predictor
Sun outage days, daily windows, and expected C/N loss for any ground station and dish size, using the shared GEO fleet, live TLEs, and ground station list.
Open tool →Sun & Moon Times
Sunrise, sunset, twilight, moonrise, moonset, and Moon phases for any ground station, with a 24-hour altitude chart and a monthly table.
Open tool →Space Weather Dashboard
Live geomagnetic and solar wind conditions from NOAA SWPC, with a plain-language satellite ops/HF radio/GNSS impact readout, auto-refreshing every 60 seconds.
Open tool →Live Satellite Tracker
Real-time position, ground track, and 48-hour pass prediction for the Indonesian GEO fleet (or any satellite by NORAD ID) using SGP4 propagation and live CelesTrak TLE data.
Open tool →ITU Filing & Coordination Tracker
Tracks satellite network filings through the ITU process (API/AP4, coordination requests, notifications) with deadline countdowns and standard timeline reference.
Open tool →Conjunction Risk Screener
Rough close-approach screening between a primary satellite and a watchlist of other objects using SGP4 propagation on public TLEs — a triage tool, not a replacement for official conjunction data.
Open tool →Indonesia Rain Fade / Link Margin Calculator
ITU-R P.618/P.838/P.839 rain attenuation calculator with rainfall statistics pre-loaded for 12 Indonesian cities from the official ITU digital maps.
Open tool →Satellite Lifetime Predictor
Estimates remaining operational lifetime from current fuel state, station-keeping strategy, and orbital longitude — quick summary plus a full fuel-budget breakdown.
Open tool →Orbital Elements 3D
Set the six Keplerian elements and see the orbit in 3D, with the ECI state vector, ground track and two-body propagation.
Open tool →Launch Tracker
Upcoming global orbital launches for the next 7 days — provider, rocket, orbit, mission details, and livestream links, from the Launch Library 2 API.
