GNSS receiver service

Diagnostics of GNSS RTK receivers, firmware updates, radio modem, NTRIP and controller set-up, antenna and cable testing.

GNSS receiver service

A healthy GNSS RTK receiver delivers ±1–2 cm horizontal and ±2–3 cm vertical accuracy and speeds up topographic surveys and setting-out considerably. Slow or unstable fixed solutions, weak radio links or a constant offset between base and rover are often caused by the equipment itself: outdated firmware, a damaged antenna cable, worn batteries or an incorrect configuration.

During service we test tracking of GPS, GLONASS, Galileo and BeiDou, signal-to-noise ratios and initialisation time under open sky. Control measurements are taken on a point of known coordinates, the antenna phase-centre height and the tilt sensor (IMU) are calibrated. UHF radio power and channels, GSM/NTRIP connections, the controller and field software such as SurvStar or Landstar are configured.

SOUTH receivers get official firmware updates and warranty service; CHC, Trimble, Leica and Topcon models are also accepted for diagnostics and set-up. Coordinate system parameters — the national grid, WGS-84 or UTM zone 39N — are configured to suit your projects in Baku and across Azerbaijan.

Control results and the work performed are documented in a service report.

FAQ

Frequently asked questions

How long does GNSS receiver service take?

Diagnostics and a firmware update are usually done within one working day. If parts are needed, the timeline is agreed in advance.

Do you configure receivers from other brands?

Yes. Besides SOUTH, we accept CHC, Trimble, Leica and Topcon receivers for diagnostics and set-up.

What does the price depend on?

On the scope of work — a simple update, configuration or repair — and on the model. We give an exact figure after diagnostics; feel free to call us.
