Quick Evaluation with Kalmix Scope

This guide shows how to quickly evaluate a SCOUT Series receiver on Android with Kalmix Scope. Connect over USB Type-C, configure NTRIP corrections, inspect NMEA output, verify an RTK Fix solution, and enable Mock Location when compatible Android apps need to reuse the corrected position.

Kalmix Scope is the official SCOUT Series evaluation and bridge app. The same system-level injection pattern also applies to validated third-party bridge tools such as GNSS Master, although menu names and screenshots may differ.

Architecture context

This guide uses Kalmix Scope to complete a quick Android RTK evaluation: connect the receiver, configure NTRIP corrections, inspect the solution, and verify RTK Fix. When other Android apps need to reuse the corrected position, Scope also supports Architecture B: System-level injection through Android Mock Location.

Before you start

Prepare the receiver, the Android device, and your correction-service credentials before starting the workflow.

SCOUT Series receiver Connect the receiver directly to the Android device through USB Type-C.
Android phone or tablet Use a device that supports USB Host / OTG operation.
Kalmix Scope Install the official bridge app before beginning the setup.
NTRIP account and network Prepare the caster address, port, mountpoint, account, password, and an active Internet connection.

USB OTG note

Many Android devices enable USB Host / OTG automatically when a receiver is connected. Some devices expose an additional OTG setting that must be enabled manually. Check the system settings if the receiver is not detected.

Setup guide

Follow the steps below in order. Keep the receiver in an open-sky environment while checking the RTK solution.

01

Connect the receiver and grant USB access

Launch Kalmix Scope, connect the SCOUT Series receiver to the Android device through USB Type-C, and approve the USB permission request when it appears.

02

Configure the NTRIP client

Open the configuration screen and enter your correction-service credentials. Set the device type to General USB, choose the required logging options, and save the configuration.

  • Enter the caster address and port.
  • Enter the account, password, and mountpoint.
  • Confirm the USB device type and log-storage preference.

03

Enable Android Mock Location when needed

Android Mock Location is optional for standalone evaluation. Enable it only when other apps need to reuse the corrected position. Assign Kalmix Scope as the mock-location provider in Android Developer Options, then enable Mock Location inside Kalmix Scope.

  • Open Android Settings → Developer Options.
  • Select Select mock location app and choose Kalmix Scope.
  • Return to Kalmix Scope and enable the Mock Location switch.

04

Start the stream and verify RTK Fix

Start the data stream, then check the logs and map view. The receiver should read NMEA output, accept RTCM correction write-back, and progress toward an RTK Fix solution under suitable sky-view and correction-service conditions.

Solution status Meaning What to check next
Single The receiver is producing a standalone GNSS solution. Confirm the NTRIP connection and RTCM correction stream.
DGNSS Differential corrections are being applied, but the carrier-phase solution is not fixed. Check correction quality, sky view, and convergence time.
RTK Float Carrier-phase corrections are available, but ambiguities are not fully resolved. Keep the receiver stationary or maintain a clear sky view while the solution converges.
RTK Fix The carrier-phase ambiguities are resolved. The bridge app is ready to provide centimeter-level positioning under suitable conditions.

05

Keep the bridge app running

After the receiver reaches RTK Fix, the evaluation is complete. When Mock Location is enabled, keep Kalmix Scope running while you open a compatible Android app. Apps that consume Android system location can reuse the injected high-precision coordinates without implementing their own USB or NTRIP workflow.

Using another bridge app

Kalmix Scope is the recommended SCOUT Series workflow for quick Android RTK evaluation. GNSS Master is a validated third-party alternative for USB serial access, NTRIP corrections, RTCM write-back, and Android Mock Location output. The configuration concept is similar, but the interface and menu names are different.
