Ubisense Tag combines UWB and GPS for ‘best-of-both-worlds’ tracking, named as CSR Location Summit Fast-Pitch finalist


Cambridge, 6th October, 2010, Ubisense Limited. Ubisense, the world leader in precise real-time location systems announces the Trimode Tag, the latest addition to its line of location tracking equipment for industrial users. The unique Trimode tag combines ultra-accurate ultra-wideband (UWB) location, low-cost presence sensing, and outdoor GPS tracking in a single device.

Inside buildings, the tag operates in the standard Ubisense UWB tracking mode, transmitting UWB signals to a network of base stations for unrivalled centimetre-level 3D location sensing. Within indoor areas, where low infrastructure cost is more important than tracking accuracy, the tag can operate in a ’presence’ mode, using its on-board radio to simply indicate that the tag is at hand. When the tag is outdoors, it automatically switches to GPS mode, calculating its position from the satellite signals, and reporting them to the Ubisense system using its on-board radio.

“We’re very excited by the possibilities afforded by the Trimode tag,” said Andy Ward, Ubisense’s Chief Technology Officer. “Our customers can now deploy a single tag to locate assets in real-time across their sites, both indoors and outdoors. We’re providing the best of both worlds – precision tracking where it’s needed indoors, and cost-effective, low-infrastructure tracking across large outdoor areas.”

Powered by a high-capacity lithium battery, and housed in a rugged IP67 enclosure, the device is suitable for a wide range of mixed indoor/outdoor applications in the manufacturing, transit and military sectors.

Learning that the Trimode tag had been named as a finalist at the CSR Location Summit Fast-Pitch awards, in the “Most Innovative Connected Location Device” category, Ubisense CEO Richard Green, said: “Our major manufacturing customers like BMW, Aston Martin and Airbus rely on our precise UWB tracking to keep their production processes running smoothly, and we can now integrate large-area outdoor tracking into the same solution. I’m delighted that this innovative product is already receiving plaudits from industry experts.”
