Spherefix GNSS products for RTK buyer glossary — Use definitions together with product pages and project requirements before final model selection.

RTK

Real-Time Kinematic positioning

RTK is a GNSS correction workflow used to improve positioning during field work when the receiver, correction source and environment are suitable.

Buyer note: Ask how corrections will be delivered in your region before choosing a receiver kit.

RTK surveying guide Base and rover setup

GNSS receiver

A GNSS receiver tracks satellite signals and is selected by application, correction workflow, field environment, controller needs and support expectations.

Buyer note: Compare product pages after confirming surveying, agriculture, machine control, monitoring or USV requirements.

GNSS receiver products Receiver selection guide

Base and rover

Base and rover workflow

A base and rover setup uses one receiver at a known reference point and another receiver in the field to support RTK correction work.

Buyer note: Confirm radio, range, tripod, controller and local workflow requirements before requesting a quotation.

Base-rover kit guide SP30 receiver

CORS / NTRIP

CORS and NTRIP corrections

CORS and NTRIP workflows can deliver correction data through a network connection when regional coverage, accounts and field connectivity are available.

Buyer note: Check network availability and account requirements before choosing between CORS/NTRIP and base-rover workflows.

Base-rover vs CORS Ask Spherefix

IMU tilt

IMU tilt compensation

IMU tilt compensation helps operators collect points with a tilted pole when the receiver and field conditions support the workflow.

Buyer note: Ask whether tilt workflow, calibration and site conditions fit your application.

Visual RTK accuracy guide SP35 receiver

Datenverbindung

GNSS datalink

A datalink supports correction or communication workflows between equipment, depending on the product, region and field setup.

Buyer note: Confirm radio frequency, local rules, range expectations and receiver compatibility before ordering.

USV survey

USV hydrographic survey

A USV hydrographic survey workflow uses an unmanned surface vessel and supporting positioning or sensing equipment for water mapping projects.

Buyer note: Share water body, payload, echo sounder, communication and support expectations before model selection.

USV solution USV products

Machine control GNSS

Machine control GNSS connects positioning, machine guidance and jobsite workflow needs for equipment such as dozers or excavators.

Buyer note: Confirm machine type, site workflow, operator display needs and dealer support before planning a demo.

Machine control solution Machine control products

GNSS monitoring

GNSS deformation monitoring

GNSS deformation monitoring supports long-term observation discussions for infrastructure, slope, dam and structural projects when configured for real site conditions.

Buyer note: Confirm monitored object, communication, power, reporting and support expectations before relying on a configuration.

Monitoring solution M6 monitoring product
