Miniature ADS-B Technology for sUAS & UTM/U-Space Implementation

Aerobits ADS-B avionics

Aerobits is a specialised developer of miniature avionics technologies for unmanned aerial vehicles (UAVs) and drones. Our hardware and software solutions facilitate the integration of unmanned aerial systems (UAS) into civilian airspace, following the guidelines laid down by aviation authorities throughout the world.

Our technology is currently the world’s smallest and fastest implementation of the ADS-B (Automatic Dependent Surveillance – Broadcast) air traffic monitoring system, providing powerful parallel computational capacity in an ultra-miniature package.

TIM-C1 – 1090MHz ADS-B UAV Receiver

Miniature ADS-B UAV ReceiverThe TIM-C1 is an OEM high-performance ADS-B receiver built around a combination of a multi-core processor and a powerful FPGA for high-speed data processing and aircraft tracking. Capable of receiving thousands of frames per second, the system utilises a high-resolution ADC with real-time signal processing based on a state-of-the-art adaptive algorithm.

RF power measurement for each frame allows distance estimation for Mode-S operation, and a GNSS input can be connected for dynamic calculations of relative distances to the aircraft. A high-sensitivity front-end provides jamming and ESD protection with a range of over 200 miles.

System integration of the module is straightforward, and communication can be achieved with a variety of simple AT commands sent over a high-speed UART.

Designed to meet the requirements of TSO-C199, the TIM-C1 is a highly scalable, flexible OEM solution that weighs just 2 grams making it ideal for a wide variety of UAV and drone applications, including Sense and Avoid / collision avoidance, UAS ground stations, mobile air traffic information, and high-density traffic surveillance and analysis.

EVAL-TIM-C1 Evaluation Kit

The EVAL-TIM-C1 is an evaluation kit allowing developers to quickly get up and running with the TIM-C1 ADS-B receiver module. The development board features a variety of additional features to allow convenient testing and evaluation of new TIM-C1 applications.

ADS-B UAV Receiver Evaluation Kit

The board is powered either by USB or an external 3.3V source. Extension I/O headers allow a GNSS source and other communications devices to be interfaced with the TIM-C1 module. 256Mb of flash memory allows off-line data analysis.

The starter kit includes a wideband antenna (0-1dBi) and a 10.5cm U.fl / SMA adapter. The included demonstration software provides 2D and 3D aircraft position visualisation and mapping.
