Inertial Sense will be releasing a high-quality, low-cost navigation system — the μINS — later this summer, the company said. The company made the announcement at AUVSI’s Xponential 2017. Inertial Sense is a privately owned U.S. company that specializes in designing and manufacturing GPS inertial navigation technology for commercial and consumer products. Historically, quality GPS inertial navigation has been expensive and was only designed into a small number of systems. As the commercial and consumer drone industries grow, the need for an accurate, low-cost navigation system has become more apparent, Inertial Sense said. Acccording to Inertial Sense, the company’s engineers have invented a design that enables the technology to be smaller and less expensive. The μINS is a tiny sensor module that is designed to provide high-quality direction, position and velocity data for drones and robotic applications. It provides this data by fusing sensor data from GPS (GNSS), gyros, accelerometers, magnetometers and a barometric pressure sensor.
