What Trace does inside an RTK workflow

Trace opens a receiver serial stream, connects to an NTRIP caster, and forwards RTCM3 corrections to the receiver while parsing incoming NMEA sentences. The interface follows a simplified four-step workflow from COM port selection to RTK fix monitoring, so the sequence of actions (connect serial, configure NTRIP, stream, observe) is explicit. That workflow targets engineers who must verify that correction traffic actually moves the receiver toward a fixed RTK solution.

How it affects a desktop or field test environment

The tool is a single-executable Windows utility that needs no installation, reducing setup time for field checks. Because it runs from one executable, it avoids background installers and uses minimal system surface area during a session. Logging separates receiver output, correction traffic, and software events, which helps reproduce issues after a test without requiring live replays of the entire session.

Safety, data handling, and operator requirements

Trace provides read/write pathways to a connected receiver by streaming RTCM3 corrections and parsing NMEA for status; users must therefore confirm correct COM settings before streaming. The app records correction traffic and serial data for offline review, which preserves an audit trail of what was sent to the receiver. The interface and visual outputs expect someone familiar with NMEA, RTCM, and RTK states rather than a purely novice operator.

Analytical outputs and suitability for diagnostics

The built-in skyplot and scatter view produce satellite geometry visuals and CEP statistics (CEP50, CEP68, CEP95) for position stability checks. Those high-resolution visualizations give engineers concrete measures of fix quality and distribution during tests. The combination of RTK state indicators (Fixed, Float, Standalone, No fix) with real-time NMEA parsing makes the tool fit for troubleshooting NTRIP-to-receiver data paths in both lab and field scenarios.

Practical diagnostic utility for GNSS engineers

Trace is a practical diagnostic utility for engineers who must verify NTRIP correction delivery and monitor RTK fix behavior. Enable full logging before field runs so you can trace connection events and correction traffic during post-test analysis. Recommended.
