Baseband Technologies Inc. has been issued a patent from the United States Patent and Trademark Office for its low-power satellite positioning innovation. U.S. Patent No. 9,116,234, titled “System, Method and Computer Program for a Low Power and Low Cost GNSS Receiver,” describes the technology and processes to significantly reduce the energy required to operate a GPS receiver. Baseband’s ultra low-power GPS receiver technology enables consumer electronics manufacturers to integrate its receiver into battery-powered wearable/Internet of Things (IoT) devices using hundreds of times less power than the traditional GPS chipsets. “With the wearable market projected to grow multiple times faster than smartphones and with GPS being one of the most requested features, there will be huge rewards for those manufacturers who can offer GPS functionality in their products without impacting the battery life or size,” said Francis Yuen, founder and CEO of Baseband. “For us, innovation is about connecting what is possible with what is valuable to our customers. This patent, in conjunction with others now pending, will enable Baseband to continue to offer ultra low-power positioning capabilities and customer-centric experiences across different market verticals.” “It is gratifying that the US Patent and Trademark Office has recognized both our invention and the intellectual property of this very promising technical advancement,” Yuen said. “This newly granted patent will certainly help in our current investment round as well as to fuel continued product development and innovation that will lead to even further advances in ultra low power positioning.”
