Power and Networking Solutions for Sensor Fusion Systems

Thursday, 1 July, 2021

Sensors have become ubiquitous on the battlefield to detect and track everything from aircraft to dismounted soldiers, and from enemy radar systems to covert communications. Electronic Warfare (EW) represents the ability to either disrupt or use electronic signals attacks. Aircraft and unmanned systems perform reconnaissance missions and pass data back to field-deployed personnel and naval platforms being protected just outside contested environments. Mapping and surveillance aircraft share data back to centralized command posts around the globe for intelligence on enemy stockpiles, troop movements and missile defense systems that share target data with central command and anti-aircraft systems to help lock down the exact location of any missile fired for acts of aggression.
This collective battlefield picture and information sharing, along with accurate and real-time location mapping starts with sensors.... read more

A Generator Control Unit (GCU) addresses the power challenges of UAVs

Tuesday, 11 May, 2021

Due to a UAV's compact and sensitive platform, there is no room for a bulky synchronous generator that allows a fixed voltage output. Likewise, the opportunity for a fixed speed engine to feed the UAV's permanent magnet generator to create a constant voltage output does not exist. A GCU (Generator Control Unit) functions as a mediator between the variable voltage and frequency alternator/generator and the stabilized DC bus requirement set by the payload. Its non-isolated topology provides high efficiency, light weight and a small form factor which makes the GCU power supply very attractive for systems that are powered by Permanent Magnet Generators (PMG) such as light weight UAVs, avionics, electronic warfare and other military applications.... read more
