Deeyook has invented a wireless-based, infrastructure-free, power-saving, and accurate indoor and outdoor positioning solution. The solution is enabled by a new mobile wireless location sensor, which is based on patented direction ascertainment technology. The sensor is at the core of a cloud-based, deep learning GPS solution that passively utilizes direction data from over a billion existing APs and base stations and operates everywhere worldwide infrastructure-free. The solution enables ubiquitous sub-meter localization, eliminates the time needs and cost of indoor location deployment, substantially reduces the power needs of GPS while enhancing its accuracy, and facilitates perpetual augmented reality synchronization.
