RTK Position App-Analysen für 1. August

RTK Position turns your Android phone into a centimetre-accurate GPS device. 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) ── PRIVACY ──────────────────────────────────────────── Location data is used solely for RTK positioning and is never uploaded or shared.
