The fastest way to get hands-on with dual-band RTK.

SCOUT Series is Kalmix's integrated RTK GNSS receiver family. Instead of requiring teams to design their own enclosure, cable, antenna mount, and integration, SCOUT packages the GNSS hardware into a compact receiver — ready to plug into your host system.

SCOUT is the entry-level configuration in the series, designed for evaluation, prototyping, education, and open-sky deployments. It's the fastest way to get hands-on with dual-band RTK without committing to a production-grade integration.

The receiver outputs standard NMEA over USB-C and accepts RTCM 3.x corrections from any compatible NTRIP source. For continuous positioning in challenging environments, see SCOUT PRO.

Five reasons makers and engineers pick SCOUT over a bare GNSS module.

Field-ready out of the box

Enclosure, integrated antenna, cable, and adhesive mount in one unit. No PCB design, no enclosure tooling, no harness work.

Dual-band L1/L5 RTK

Multi-constellation tracking with cm-level RTK accuracy when paired with any standard NTRIP correction stream.

Standard interfaces

USB-C, NMEA 0183 output, RTCM 3.x input. Reads as a USB serial device on Linux, Windows, and macOS.

Motion-aware variant

RTK+DR version adds a 6-axis IMU to support continuity during short GNSS interruptions on dynamic platforms.

SCOUT is an integrated RTK GNSS receiver for open-sky evaluation, education, early prototyping, and cost-sensitive outdoor projects.

All values reflect publicly disclosed product specifications. Compatibility with specific software versions may require integration steps documented on GitHub.

Answers for engineering teams.

Practical answers about RTK corrections, integration, mounting, documentation, and support.

Can SCOUT achieve RTK accuracy without corrections?

No. Centimeter-level RTK accuracy requires RTCM 3.x correction data delivered to the receiver through a host system running an NTRIP client. The correction source can be a public NTRIP service, a regional CORS network, or a local base station. Without corrections, SCOUT operates in standalone GNSS mode with meter-level or sub-meter typical accuracy depending on environment and sky view.

What is the difference between SCOUT Standard and SCOUT RTK+DR?

Both variants share the same integrated G-Mouse form factor, USB-C interface, NMEA output, and RTCM correction input. The RTK+DR variant adds a 6-axis IMU based on BOSCH BMI325 and supports 10 Hz output, while the standard RTK variant is intended for 1 Hz GNSS-based positioning. Choose the standard version for open-sky evaluation, education, early prototypes, and cost-sensitive field tests. Choose RTK+DR for moving prototypes and open-sky platforms that benefit from IMU-assisted continuity.

Can SCOUT be used as a base station?

SCOUT is primarily designed as a rover receiver. It can be used in base-like workflows with suitable host software, a stationary reference position, and an NTRIP or RTCM correction pipeline, but it is not a dedicated radio base station kit. For base station or fixed reference setups, contact Kalmix for recommended configuration options.

Do I need a separate GNSS antenna?

No. SCOUT is an integrated G-Mouse receiver with the GNSS antenna built into the enclosure. You only need a USB-C connection to your host system and an RTCM correction source when RTK positioning is required.

Which NTRIP services does SCOUT work with?

SCOUT can work with NTRIP services that provide RTCM 3.x correction data compatible with multi-constellation RTK receivers. This may include public CORS networks, commercial NTRIP subscriptions, and self-hosted base station services. The NTRIP client usually runs on the host computer, which forwards RTCM data to the receiver over USB serial.

Will it work with my Raspberry Pi, Jetson, or laptop?

Yes. SCOUT connects through USB-C and outputs standard NMEA 0183 data over a serial interface. It is designed for common host systems including Raspberry Pi, NVIDIA Jetson, Linux computers, Windows PCs, and macOS systems. Integration examples and reference resources are available through the Kalmix GitHub organization.

How is SCOUT mounted on a vehicle or robot?

SCOUT uses an integrated enclosure and ships with mounting adhesive for direct installation on vehicles, robots, field machines, or test platforms. For best GNSS performance, mount it on a stable top-facing surface with the clearest possible sky view and minimal obstruction from metal structures, payloads, or nearby electronics.

Is there volume pricing for OEM or project orders?

Yes. Volume pricing is available for project and integration teams. Typical inquiries include robotics fleets, AGV platforms, agricultural equipment, research programs, and OEM evaluation batches. Use the contact form to share your target product, application, quantity, and expected timeline.

What documentation is available?

Public product overview, technical specifications, protocol references, and get-started guides are available through the Kalmix Support Hub. Additional engineering files, mechanical drawings, certification documents, configuration tools, and integration resources may be available on request.

What is the warranty and support policy?

SCOUT includes a 12-month limited hardware warranty against manufacturing defects. Technical support is provided by email for product setup, documentation questions, and basic integration guidance. For volume or OEM projects, dedicated support arrangements can be discussed during the quote process.
