It captures raw GNSS carrier-phase measurements, applies Real-Time Kinematic (RTK) corrections streamed live from any NTRIP caster (rtk2go, your own base station, national CORS networks), and injects a high-precision mock location into Android — available to every navigation and mapping app on your device.

── WHAT IS RTK? ───────────────────────────────────────
Standard GPS is accurate to 2–5 metres. RTK uses a fixed reference station and carrier-phase mathematics to resolve positioning down to 1–3 cm horizontally. The same technology powers professional survey equipment; RTK Position brings it to compatible Android hardware.

── FEATURES ───────────────────────────────────────────
• Live RTK fix — SPP → Float → Fixed solution display with σH, satellite count and age of corrections
• Satellite skyplot — compass-oriented with C/N₀ colour bars and constellation labels
• NTRIP client — connects to any NTRIP 1.0/2.0 caster; automatic reconnect with backoff
• Validation mode — measure your position precision: σE/σN/σU, CEP50, CEP95, DRMS, error ellipse
• Mock location injection — replaces Android GPS provider with the RTK solution; works with Google Maps, OSMAnd, QGIS Mobile, and more
• Debug log — capture and share diagnostic logs directly from the app

── PRO FEATURES ───────────────────────────────────────
Unlock with a single one-time purchase:
• Unlimited NTRIP profiles (free tier: one profile)
• Mountpoint browser — fetch the source table and pick the nearest base station by distance
• Full session history — review every validation run
• E/N/U time series chart — see position drift over time
• CSV export — share raw sample data for post-processing
• Advanced engine settings — constellation toggles, elevation mask, GLONASS AR
• Raw GNSS data logging

── REQUIREMENTS ───────────────────────────────────────
• Android 8.0 (API 26) or newer
• Phone with raw GNSS measurement support (carrier phase)
Confirmed: Pixel 4+, Samsung Galaxy S20/S21+, Snapdragon 855+ devices
• Developer Options → Mock Location app must be set to RTK Position
• NTRIP caster account (rtk2go.com is free to use)
