RTKapp

Welcome to RTKapp

Centimeter Precision in your Pocket RTKapp is the ultimate solution for surveyors, engineers, and GNSS enthusiasts who need professional workflows without the burden of desktop software. Connect, record, process, and analyze satellite data directly from your iPhone or iPad in a fast, private, and powerful way.

Powered by the robust RTKLIB engine (Demo5), RTKapp allows you to execute RTK positioning, Post-Processing (PPK/PPP), and raw data conversion in seconds, wrapped in a modern, streamlined interface.

REAL-TIME RTK

• Total Connectivity: Connect your GNSS receiver via Bluetooth (BLE) or TCP, or get network corrections through the built-in NTRIP Client.
• Live Quality Metrics: Monitor your signal status in real-time with AR ratio, HRMS/VRMS, DOP, SNR (Signal-to-Noise Ratio), and Skyplot views.
• VRS Support: Works seamlessly with Virtual Reference Stations by automatically sending your configured position (GGA) to the caster.
• Transparent Recording: Natively capture and log raw data streams from the Rover, Base, and corrections simultaneously while you measure.

INSTANT POST-PROCESSING

• Load your observation (Rover/Base) and navigation files on the fly.
• Execute kinematic, static, or precise point positioning (PPP) with advanced algorithms.
• Analytical Plotting: Dive deep with E/N/U position graphs, horizontal scatter plots, cycle slip detection, and post-fit phase residuals to ensure maximum survey-grade quality.

FIELD PRO TOOLS

• RINEX Converter: Import binary logs from RTCM3 and export them to universal RINEX format with advanced versioning and frequency selections (L1/L2/L5).
• NTRIP Caster Management: Browse sourcetables, save profiles for your favorite VRS networks, and even share data by forwarding corrections via Bluetooth.
• Configuration Profiles: Save your processing settings, elevation masks, and ambiguity resolution parameters into custom profiles for instant field readiness.

LOCAL PRIVACY FIRST

Your data belongs to you. RTKapp processes all positioning locally right on your device. We do not rely on the cloud to calculate your position, we don't track your projects, and all exports to GPX, KML, CSV, or .pos coordinate files are performed purely on-demand.
