Receiver technologies
The AG3335-series platform includes assistance and interference-control functions for receiver evaluation and deployment.
EPO extended orbit prediction
EPO supports assisted GNSS workflows by loading extended ephemeris data. It can reduce cold-start time when initial satellite navigation information is unavailable or incomplete.
EASY embedded assist system
EASY uses local memory to calculate and predict satellite orbit data for up to three days without requiring a network connection.
Active interference cancellation
AIC supports multi-frequency suppression of up to 12 independent continuous-wave interference sources from nearby electronic components.
Antenna and inertial sensors
SCOUT PRO 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 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 | ST LSM6DSR 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. |
Data and communication
SCOUT PRO 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. |
