A Smart IoT sensor nodes delivering simplified yet information rich PDR data for superior personnel tracking performance in GPS denied environment. Onboard navigation computation relieves application platform and developers from the compute intensive development, thereby enabling relaxed constraints on the integration platform, and significantly reduced time-to-market.
An extremely compute intensive sensor node with nearly 300 inertial sensing elements squeezed systematically on a board of size less than 1/3rd of a credit card, providing the backend with high level information at nominal data rate. An onboard 32b floating pointt controller enables localized computation, and USB connector & optional Bluetooth interface enable data transfer flexibility.
The sensor platforms have a simple data interface that outputs Pedestrian Dead Reckoning (PDR) data at every step. In simple words, the foot-mounted device (IMU) detects steps of its wearer, computes displacement and heading of each detected step with respect to the previous one and transmits it over Bluetooth interface to application platform for construction of the tracked path.
