Receiver architecture

SCOUT integrates the NOMAD K16-series GNSS module, antenna, enclosure, mounting surface, and USB host interface into a single receiver assembly.

NOMAD K16-series core module

Standard RTK uses the K16C module. RTK + DR uses the K16E module with integrated inertial-sensor support.

Integrated dual-band antenna

The receiver includes a dual-stacked ceramic patch antenna covering L1 and L5 bands without requiring an external antenna cable.

USB serial integration path

SCOUT exposes NMEA output, configuration commands, and RTCM correction-data input through its integrated USB Type-C host connection.

Antenna and inertial sensors

SCOUT integrates a dual-band ceramic patch antenna. The RTK + DR configuration additionally includes an inertial sensor for short GNSS-degraded intervals.

Parameter Specification
GNSS antenna Built-in high-gain dual-stacked ceramic patch antenna: 33 × 33 × 6 mm and 25 × 25 × 4 mm.
Frequency ranges L1 band: 1559–1606 MHz
L5 band: 1167–1249 MHz
Inertial sensor RTK + DR only BOSCH BMI325 6-axis IMU for dead-reckoning sensor fusion.
Dead-reckoning performance RTK + DR only Position error is typically ≤ 4% of distance traveled during complete GNSS signal outages.

SCOUT exposes serial GNSS data through its USB Type-C host interface and accepts correction data for RTK workflows.

Parameter Specification
Output protocol NMEA 0183: GGA, GSA, GSV, RMC, GLL, VTG, and GST.
Correction input RTCM v3.x. Review Protocol for message and integration details.
Default baud rate 115,200 bps
Configurable baud rate Up to 921,600 bps. Serial configuration: 8 data bits, no parity, 1 stop bit.
