GNSS Systems

Multi-Constellation, Multi-Frequency RTK GNSS Receivers

Aeron's DENEB family of GNSS receivers delivers centimetre-level RTK positioning across man-portable, rugged and tactical form factors — engineered for autonomous vehicles, robotics, survey and defence platforms.

Key Features

  • Multi-Frequency, Multi-Constellation GNSS

    L1/L2/L5 RTK GNSS receiver tracking up to six satellite constellations simultaneously.

  • Ruggedized for Mechanical Shock

    Qualified to MIL-STD-810G shock, vibration and temperature test standards.

  • Real-Time Position Outputs

    Continuous position, velocity and time data streamed for live navigation and control.

  • Centimetre-Level RTK Accuracy

    Centimetre-level position accuracy in Real Time Kinematic (RTK) mode.

  • High-Accuracy 1PPS Output

    UTC-synchronized 1PPS timing output for precise time synchronisation.

  • Multiple Interfaces

    RS232, RS422 and Ethernet connectivity across the receiver family.

  • Rugged IP65 Enclosure

    Sealed enclosure rated IP65 for harsh field and tactical environments.

  • Status LED Indicators

    Power/Health, GNSS Fix and Communication LEDs for at-a-glance status monitoring.

The Precision Positioning Challenge

Autonomous platforms, survey crews and defence systems all depend on positioning that stays accurate under pressure — through mechanical shock, extreme temperature, high vibration and contested electromagnetic environments. A single-frequency or single-constellation receiver simply isn't built to survive that.

  • Signal Reliability

    Jamming, multipath and constellation dropout degrade single-band receivers exactly when accuracy matters most.

  • Environmental Extremes

    Field and tactical deployments demand survival across shock, vibration, temperature and ingress conditions.

  • Form-Factor Fit

    A hand-held survey rover and an armoured ground vehicle need fundamentally different receiver footprints.

Aeron's Approach: One Solution, Every Deployment Profile

Rather than a single receiver, Aeron's GNSS Systems solution is built as a family — sharing one multi-frequency, multi-constellation GNSS core across three purpose-built form factors. Whichever profile a program needs, the underlying positioning engine, protocol stack and qualification standard stay consistent.

That means a survey team, a robotics integrator and a defence platform can all standardise on the same GNSS approach — from the man-portable, RF-modem integrated GBM200, to the rugged RS232/Ethernet GN402, to the 500 g shock-rated, tactical-grade GN404 — all tracking GPS, GLONASS, Galileo, BeiDou, QZSS and NavIC (IRNSS).

What the Solution Delivers

  • Centimetre-level RTK accuracy across the entire receiver family
  • Multi-frequency L1/L2/L5 tracking with 6 GNSS constellations
  • Form factors from hand-held to tactical-grade, mission-critical
  • Common NMEA 0183 / RTCM protocol stack across models
  • MIL-STD qualified for rugged and defence deployment

How the Solution Works

Across every receiver in the family, signals from up to six GNSS constellations are tracked simultaneously and fused with RTK correction data to resolve position down to 1 cm CEP.

Why Aeron for GNSS

  • Indigenously Designed

    The Deneb receivers are designed and manufactured in-house by Aeron, not re-badged third-party modules.

  • MIL-STD Qualified Across the Range

    Every model in the family is qualified to MIL-STD-461E/F and MIL-STD-810G for EMI/EMC and environmental survivability.

  • One Vendor, Full Spectrum

    From man-portable to tactical-grade, a single GNSS partner covers hand-held, rugged and mission-critical needs.

  • Long Program Life Support

    Consistent architecture across models simplifies long-term sustainment and spares planning for multi-year programs.

  • Broad Interface Support

    RS232, RS422, USB, 1PPS and Ethernet interfaces are supported across the Deneb series.

  • Integrated RF Modem Variant

    Select models include an integrated RF modem for RTK corrections, with full NavIC compatibility across the range.
