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.
L1/L2/L5 RTK GNSS receiver tracking up to six satellite constellations simultaneously.
Qualified to MIL-STD-810G shock, vibration and temperature test standards.
Continuous position, velocity and time data streamed for live navigation and control.
Centimetre-level position accuracy in Real Time Kinematic (RTK) mode.
UTC-synchronized 1PPS timing output for precise time synchronisation.
RS232, RS422 and Ethernet connectivity across the receiver family.
Sealed enclosure rated IP65 for harsh field and tactical environments.
Power/Health, GNSS Fix and Communication LEDs for at-a-glance status monitoring.
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.
Jamming, multipath and constellation dropout degrade single-band receivers exactly when accuracy matters most.
Field and tactical deployments demand survival across shock, vibration, temperature and ingress conditions.
A hand-held survey rover and an armoured ground vehicle need fundamentally different receiver footprints.
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).
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.

The Deneb receivers are designed and manufactured in-house by Aeron, not re-badged third-party modules.
Every model in the family is qualified to MIL-STD-461E/F and MIL-STD-810G for EMI/EMC and environmental survivability.
From man-portable to tactical-grade, a single GNSS partner covers hand-held, rugged and mission-critical needs.
Consistent architecture across models simplifies long-term sustainment and spares planning for multi-year programs.
RS232, RS422, USB, 1PPS and Ethernet interfaces are supported across the Deneb series.
Select models include an integrated RF modem for RTK corrections, with full NavIC compatibility across the range.
One GNSS solution, deployed across defence, autonomy and precision field operations.
Shock-rated, MIL-STD qualified positioning for platforms operating in contested and high-vibration environments.
Centimetre-level RTK feedback for closed-loop navigation and control on unmanned platforms.
Hand-held to vehicle-mounted receivers for precision mapping, marine navigation and field operations.
The solution is delivered through the Deneb receiver series — three form factors on one common GNSS core.
