Ground Station

Ground Station is an open-source, browser-based application for tracking satellites and celestial targets,
controlling station hardware, and receiving, decoding, and recording SDR signals. Built for amateur radio
operators, satellite enthusiasts, and researchers, it brings orbit visualization, multi-target tracking consoles,
SDR waterfall analysis, packet and telemetry decoding, scheduled observations, and hardware management into a
single web interface.
Recent Releases
- v0.8.22 (2026-10-26): Added LASARSAT AX.25 beacon decoding with viewer support. Satellite tracking gained observer-context updates, rotator and image-handling improvements, live navigation status indicators, and command expiration with backend epoch tracking. Earth View added map title controls for fullscreen and home centering with steadier globe fitting, and the reorganized VFO panel improves filtering and readability. LoRa decoded packets now show satellite links and refined callsign hints, while connection popovers and traffic statistics render more responsively.
- v0.8.21 (2026-10-25): Added live and scheduled LoRa decoding with configurable receiver profiles, dynamic VFO controls, and TinyGS transmitter data in orbital synchronization. Earth View and satellite tracking now support OMM orbit propagation, and UMKA-1 USP telemetry is decoded into readable engineering values. Recording views gained transmitter frequency markers and waterfall-generation progress, while the file browser gained observation and type filters with more reliable paging. Satellite and transmitter editing, VFO transmitter locking, and scheduler dialogs also received clearer controls and responsiveness improvements.
- v0.8.20 (2026-10-20): Ground Station has gained a documented public API with scoped access tokens, live event streams, and artifact downloads. Transcription now supports Parakeet, with Google Translate and LibreTranslate options. GNSS updates improve tuning guidance, pseudorange data, and fix handling, while transmitter settings add FSK framing and deviation controls. Observation scheduling now supports rig selection and clearer conflict choices; the file browser adds a purge preview. This update also improves SDR error reporting and lets Docker deployments configure the Nginx HTTP port with GS_HTTP_PORT.
- v0.8.19 (2026-10-11): Expanded Simplified Chinese coverage across the current interface and made many previously hardcoded labels, prompts, tooltips, and status messages translatable. Added guidance for extending other language packs and corrected satellite service filtering so translated labels select the right data.
- v0.8.18 (2026-10-08): Added the ability to join a live SDR stream with independent VFOs, plus improved device capability detection and controls for taking over shared SDR settings. Satellite views now show live positions and future passes, offer quicker access to recent groups, and provide more actions from pass tables. Maintenance gained release status and Docker update guidance. Voice squelch now rejects hiss more effectively, with a longer adjustable close delay and smoother FM demodulation.
- v0.8.17 (2026-10-06): This release substantially improves interface responsiveness with incremental rendering of maps and dashboard panels, batched live-data updates, fewer unnecessary frame callbacks, and smoother VFO interactions. It also adds synchronized VFO audio controls, richer observation and decoded-file management, improved SatDump failure recovery, and refinements to waterfall, rotator, targeting, and Solar System displays.
- v0.8.16 (2026-09-30): This release expands satellite catalog management with dedicated orbital-data pages, lifecycle timestamps, improved search, filtering, pagination, and table layouts. It also refines the celestial catalog and Solar System display with clearer object labels and an option to hide labels for unfocused objects, improves waterfall decoded-packet and observation asset links, and includes reliability improvements for setup-wizard logout handling.
- v0.8.15 (2026-09-29): Added vector coverage details and unified property editing across celestial target context menus; improved celestial-pass pagination as results change; and optimized Earth trajectory caching with minimal non-dominated projections, duplicate-free canonical target updates, and clearer synchronization progress.
- v0.8.14 (2026-09-28): Added configurable projections for monitored celestial objects, richer visibility and trajectory displays, Earth-relative distance, velocity, light-time, Doppler, and closest-approach metrics; improved ephemeris caching, cleanup, synchronization, and progress reporting; added configurable rotator tracking lead time; and refined dashboard status indicators, task feedback, toolbar navigation, and translations.
- v0.8.13 (2026-09-25): Added celestial-data administration with ephemeris synchronization, live status, resilient NASA JPL Horizons fallback, vector coverage history and cleanup; improved celestial projection controls and target tracking; added azimuth columns to satellite and pass tables; and strengthened observation, tracker, and shutdown reliability.
