SCOUT Android Quick Start with SCOPE

Connect a SCOUT Series receiver to Android, send it NTRIP corrections through SCOPE, and check the RTK status reported by the receiver.

How the system works: SCOPE manages the USB and correction connections. SCOUT or SCOUT PRO calculates the position and reports its solution state; SCOPE displays that state.

Before you start

  • A SCOUT or SCOUT PRO receiver and a USB-C data cable.
  • An Android 15 or 16 phone or tablet with USB Host / OTG support and SCOPE for Android installed. This quick start follows SCOPE v1.0.7.
  • An internet connection and your NTRIP caster, port, mountpoint, and credentials if required by the service.
  • An outdoor location with a clear view of the sky for the RTK check.

Choose the SCOPE Device Type and Baud Rate for your receiver version. The default baud rate for each version below is 115200 bps; if the receiver was reconfigured, use its current setting.

Product version Device Type Default baud rate
SCOUT RTK / RTK+DR USB Serial 115200
SCOUT PRO RTK USB Serial 115200
SCOUT PRO RTK+DR USB Serial for standard output; Super USB Serial for the validated high-rate setup 115200

For a configured high-rate SCOUT PRO RTK+DR setup, choose Super USB Serial and match the receiver's current baud rate. The SCOPE User Guide explains that mode.

Open the receiver in SCOPE

  1. Plug SCOUT into the Android device and open SCOPE.
  2. Allow USB access when Android asks, then open Device.
  3. Select the Device Type and Baud Rate from the table above for your receiver's active configuration.
  4. Confirm the detected serial port, then tap Connect.

Connection check: the Device control changes to Disconnect. On the Dashboard, the GNSS RECEIVER card shows a connection; under Status → NMEA, the live stream shows Streaming.

If it does not connect, check the data cable, USB permission, device type, and baud rate.

Set up the NTRIP source

  1. Open Corrections → Source.
  2. Enter the host, port, mountpoint, and any required username and password supplied by your correction provider.
  3. Enable Send NMEA GGA to Base Station only when a VRS or NEAR service requires the rover position.
  4. Turn on SAVE if you want to reuse these settings on this Android device, then tap Connect.

Source check: the source control changes to Disconnect. This confirms the NTRIP connection; check the RTCM stream separately.

Check that corrections are arriving

  1. Open Corrections → RTCM and confirm it shows Streaming.
  2. Check that Messages and Bytes increase, while Age (s) keeps refreshing instead of steadily climbing.

Correction check: RTCM data is arriving while the receiver connection remains active. An NTRIP source showing Connected alone does not complete this check.

Read the receiver's RTK status

  1. Open Dashboard and keep the receiver outdoors with a clear sky view.
  2. Wait until the receiver reports RTK Fixed while corrections remain active.

Single, DGPS, and RTK Float are not RTK Fixed; Inertial / DR on a supported RTK+DR receiver is also a different state. If the receiver stays at Single, DGPS, or Float, follow Check the session in layers in the SCOPE User Guide.

Solution check: the receiver reports RTK Fixed while corrections remain active. This is a setup check, not an independent accuracy measurement.

When finished: on Corrections → RTCM, tap Stop RTCM. Disconnect the NTRIP source under Corrections → Source, then tap Disconnect on the Device page before unplugging the receiver.
