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.


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.


The BMR4-40 drone is capable of accommodating diverse payloads weighing up to 4kg, 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.
