Corrections aren’t a black box. Measure them.

Stream validator

Connect to a correction stream (mountpoint) and watch the verdict: correction age, message cadence and the reference station’s satellites. Plain language — with full RTCM detail for experts.

Problem diagnosis

Data gaps, stale corrections, a missing position (GGA) for a virtual station (VRS), irregular cadence. Fixcast tells you what is happening and why — not just “it doesn’t work”.

Map and surroundings

Correction streams sorted by distance, the baseline to the reference station, the anonymous experience of others over the last hour — and the current ionospheric turbulence measured nearby.

For network operators

See your network the way the rover sees it.

A surveyor who can’t get a FIX won’t complain — they just won’t come back. Fixcast drops a diagnostic report straight into your support and tells you whether the fault is your stream or the user’s end. Data instead of an “it doesn’t work” phone call.
