Core Advantages

AIM
01 · Anti-Jamming

AIM+ Anti-Jamming

  • Jamming: actively detects & suppresses narrowband CW and wideband/pulsed interferer signals.
  • Anti-spoofing: rejects malicious spoofed signals for trustworthy positioning.
  • Spectrum: real-time RF interference monitoring via the Web UI.
GNSS
02 · All-Constellation

All-Constellation Tri-Band

  • Systems: GPS / GLONASS / Galileo / BeiDou / QZSS / NavIC / SBAS — no coverage blind spots.
  • Bands: L1 / L2 / L5 tri-band tracking across high-performance frequencies.
  • Urban: stronger multipath resilience than dual-band in city canyons.
RTK
03 · cm-level & Heading

cm-level & Dual-Antenna Heading

  • Rate: up to 20 Hz RTK output for UAV, robotics & fast-moving platforms.
  • Precision: centimeter-level RTK with 0.15° heading accuracy.
  • Heading: P3H dual-antenna, magnetometer-free — valid while stationary.
LOCK
04 · Robust Tracking

LOCK+ / IONO+ / APME+

  • LOCK+: vibration-robust tracking for heavy machinery & multi-rotor drones.
  • IONO+: mitigates ionospheric scintillation during high solar activity.
  • APME+: reduces multipath reflections from buildings & ground.
PWR
05 · Low Power

Compact & Low Power

  • Power: ≈0.44–0.6 W typical — highly efficient for RTK.
  • Size: all GNSS logic in a 22×16 mm module footprint.
  • Integration: simplified RF design for compact product integration.
