Company insight
analyse, predict, report and transmit a wide range of information. The Talon, developed by Qinetiq, is a highly transportable robot capable of operating in adverse weather and terrain conditions. It swiftly navigates rugged environments, carrying customised electronic equipment that enables remote control from behind the front lines and rapid delivery of supplies. The Talon robot can also deploy weaponry from its own chassis. Cables and connectors used in such equipment must be waterproof and efficiently distribute power while facilitating remote directional control, image capture and transmission. Connectors used in military and aerospace ground robotics applications must meet specific requirements for low weight and exceptional reliability in the face of shock and vibration. Rigorous test specifications are defined to ensure dependable performance. Many applications necessitate the use of metal back shells and braided metal shielding on the cable to prevent damage and provide electromagnetic interference (EMI) shielding. With increasing signal speeds and the need to accommodate more
electronic components in compact spaces, this becomes increasingly crucial.
Connecting the troops The deployment of soldier-worn electronic systems is widespread, reflecting the era of high-technology digital battlefields. Continuous communication with each ground trooper and biomonitoring are vital for personnel protection. Higher speed signals play a critical role in supporting life and facilitating efficient sharing of critical data from satellites, unmanned vehicles, and ground central hubs. Directions for munitions from the ground team are processed by the soldier’s onboard computer, which is linked to a military GPS satellite overhead.
The connectors and cables used in wearable military applications must meet three essential criteria: reliability, lightweight construction and optimal signal integrity. Each new design undergoes a thorough review to assess its compatibility with the soldier’s equipment pack and uniform. The fabrication process includes testing for electrical and mechanical specifications that the soldier will
encounter in the field and feedback plays a crucial role in ensuring the usability of these components.
The process of configuring connectors for application-specific functions typically begins with an evaluation of the equipment they will be applied to. Standard and commercial off-the-shelf (COTS) connectors can be considered and analysed to find a close match for the new application. If shape or size modifications are necessary, the connector supplier can quickly create a solid model of the new design, initiating online collaboration with the system design team to ensure early accuracy. As signal speeds increase, careful planning for cables becomes crucial. Higher-speed differential signal processing pushes the limits of standard cables in our industry. Cable design must address signal length, attenuation and skew of differential signals. Techniques such as using TDR instruments or analysing eye diagrams with noise, jitter, and skew help in evaluating the cable’s performance as signals pass through it. ●
