SCOPE FEATURES

See the data behind your receiver session.

Set up an NTRIP source, inspect live NMEA and satellite views, and keep local records when you need them.

CORRECTION SOURCE

Set up your correction source.

Enter the NTRIP settings supplied by your correction provider. SCOPE receives the stream and forwards incoming RTCM data to a compatible USB serial receiver.

  • Caster address, port, and mountpoint in one place
  • Optional credentials and GGA uplink when required
  • Check corrections and receiver status independently

LOCAL RECORDS

Save local session logs.

Choose local NMEA, RTCM, and event logs for later review or support.

SCOPE WORKFLOW

From USB connection to a session you can review.

Connect the receiver, add corrections when required, inspect the reported solution, and keep the data needed for review.

Connect

Open the receiver stream.

Connect over USB-C, allow USB access, and select the matching device type and baud rate. Confirm that NMEA data is arriving.

Correct

Add your NTRIP source.

Enter the settings supplied by your correction provider. Connect the source, then check the incoming data in the RTCM view.

Verify

Review the receiver's solution.

Read the reported position state, correction age, and satellite information. Use Map and Skyplot for additional context.

Record

Keep the session data you need.

Choose NMEA, RTCM, or event logs when recording is required. Stop the correction stream and disconnect the receiver when finished.

SCOPE USE CASES

Practical checks, wherever the receiver is.

Use SCOPE during receiver setup, correction troubleshooting, Android app integration, and technical support.

SET UP

Field receiver checks

Use an Android device to inspect the USB connection, receiver output, and reported position before continuing with your work.

USB connection live status

TROUBLESHOOT

Correction path troubleshooting

Review the NTRIP source, incoming RTCM data, and receiver status to narrow down which part of the session needs attention.

INTEGRATE

Android app integration

Use Android Mock Location when the target app accepts system-location input. Verify that the target app is using the receiver position before fieldwork.

SCOPE HARDWARE

Built for SCOUT Series, open to compatible USB serial receivers.

SCOPE is built for the Kalmix SCOUT and SCOUT PRO USB-C workflow. The Android device must support USB Host / OTG when connecting a USB receiver. Other receivers need a compatible USB serial interface and validation of the exact setup.

SCOPE FAQ

A few notes before you install SCOPE.

Answers about Android setup, receiver connections, corrections, and the Android APK.

Is SCOPE free to use?

Yes. SCOPE is free to use. A compatible GNSS receiver is required, and any correction-service account or fees are separate.

What are the Android device requirements?

SCOPE requires Android 7.0 or later, a 64-bit ARM device (arm64-v8a), and OpenGL ES 3.0 support. USB Host / OTG support is required when connecting a USB GNSS receiver.

Can I use a receiver other than SCOUT?

SCOPE is built for SCOUT and SCOUT PRO over USB-C. Another receiver may work if it exposes a compatible USB serial interface, outputs standard NMEA, uses a baud rate available in SCOPE, and accepts the required RTCM input. Validate the exact setup before field use.

Can SCOPE connect over Bluetooth?

The workflow documented for this release uses USB-C / USB serial. Bluetooth is not part of the verified workflow presented on this page.

Does SCOPE include an NTRIP correction service?

No. SCOPE provides the NTRIP client connection. Your correction provider supplies the caster address, port, mountpoint, and any required credentials.

Do I need Mock Location?

Only when a compatible Android app needs the receiver position through Android system location. Mock Location is not required to inspect receiver data or deliver RTCM corrections. Confirm that the target app accepts the position before fieldwork.

Does RTK Fixed guarantee that my position is correct?

No. SCOPE displays the state reported by the receiver; it does not independently measure position accuracy. Position quality still depends on the receiver, antenna setup, correction source, and operating conditions.

What can SCOPE record?

SCOPE can save receiver NMEA output, incoming RTCM data, and system event or status logs locally. Enable only the categories needed for your session.
