Key Features

Carbon Fiber Construction

Australian-designed molds, coupled with an advanced autoclave prepreg CFRP construction process, ensures that Bremer airframes are both lightweight and robust.


Bremer employs dual RTK-capable GNSS systems for precise tracking of automated flight paths, also providing redundancy as a secondary position source.

Secure Datalinks

Open architecture allows the BMR to utilize advanced & secure datalinks and multipoint repeaters to extend its range to unparalleled distances.

Propulsion System

Bremer drones benefit from a modular & flexible propulsion system, enabling the use of diverse powerplants to optimize flight under varying conditions, including temperature, elevation, and durability requirements.

AI Coprocessor

To address emerging autonomy requirements, the Bremer drone can employ an NVIDIA GPU-based AI co-processor, enabling real-time edge computing for processing flight, sensor and instrument data on the fly.


Bremer offers the capability to fly multiple payloads in a single flight configuration. Our in-house engineering team facilitates the integration of sensors & payloads with the flight avionics and co-processing suite, unlocking advanced functionalities.

The Bremer is an Australian designed and built drone platform, allowing full flexibility of adapting datalinks, co-processors and other system elements to operational requirements.

Redundant Powerplant

The Bremer’s 8 motors add redundancy to aid stable flight & recovery in the rare event of a motor failure. Unlike a parachute recovery system, the Bremer provides this capability at low altitudes, commonly encountered in monitoring applications*.

Payloads & Applications

The BMR4-80 drone is capable of accommodating diverse payloads weighing up to 10kg, emphasizing its swift integration and adaptable design.


The BMR4 excels in seamlessly carrying a myriad of payloads for surveying, multispectral/hyperspectral, lidar, and environmental applications.


Power, infrastructure, firefighting & law enforcement applications that require rapid integration and adaptability for demanding operational scenarios.


Persistent communications relay/ repeaters, RF analyzers and other instruments that require radio silence from the drone platform.

Quality & Compliance

Open architecture allows rapid deployment of meteorological sensors, chemical detectors, air quality instruments & water samplers.


Advanced RPAS training platform for first responders, government & industrial applications, allowing simulated scenarios & emergencies.

AI & Bespoke

Expertise in mechanical, electronic, & software, coupled with on-board AI co-processors, enhances the drone’s capabilities for demanding applications.

Powerlines & Subsystems

The Bremer, equipped with ultra-high-resolution imagers designed for detecting defects in conductors, pylons, and various infrastructure, combined with flight planning software & advanced analytics dashboards, provides a comprehensive end-to-end enterprise solution.

Precision Payload Delivery

Our in-house engineering design and manufacturing expertise enables the rapid integration of delivery deployment, and dosing mechanisms. Deep avionics integration allows for multi-mission capability, including remote payload control, monitoring & communication relay.

Hybrid Engine Upgrade

The Bremer 80 drone is retrofit-ready with a fuel-injected hybrid engine, elevating its endurance to over 2 hours. This extended capability proves advantageous for continuous monitoring and other evolving BVLOS applications. Our engines, crafted in Australia, ensure unparalleled reliability.
