Stream Inspector
Connect to a live GNSS stream and work it in one place — inspect every message (types, rates, bandwidth, decoded fields), grade quality, solve a live position, run an RTK baseline and record RINEX. NTRIP, raw TCP or a USB receiver (WebSerial); format auto-detected and decoded entirely in your browser. For the NTRIP-first view with sourcetable browsing, use NTRIP.
Network-RTK / VRS position (optional)
Sends an initial GGA — needed by VRS / Nearest / MAX mountpoints (the sourcetable “nmea” flag).
Frequently Asked Questions
- What is the stream inspector for?
- It connects to a live GNSS stream and shows you every message flowing through it — type, rate, size and decoded content — so you can debug a caster, a base station or a receiver. Think of it as a visual str2str with a built-in RTCM dissector.
- What can I connect to?
- An NTRIP mountpoint, a raw TCP host:port (both via a read-only relay), or a USB receiver directly over WebSerial (Chrome/Edge). The wire format is auto-detected — RTCM3, u-blox UBX, Septentrio SBF, NovAtel, Trimble, BINEX or NMEA — and everything is decoded in your browser.
- What does it decode?
- Every RTCM3 message is identified, counted and rate/bandwidth-tracked; MSM1–7 observations (all constellations), ephemerides and station/antenna descriptors are decoded field-by-field, and the receiver binaries (UBX, SBF, NovAtel, Trimble, BINEX) get the same field-by-field dissector as the file converter. The summary shows the message mix, per-type rates, bandwidth, and — for RTCM3 — the satellites, C/N0 and station position being broadcast.
- Does anything leave my machine?
- Only the connection to the caster you choose, relayed through the CORS proxy so the browser can reach it. The stream is decoded and inspected entirely client-side; nothing is stored.
