Abstract: Systems and methods of determining a device position are described. GPS and cellular signals, in addition to VIO displacement are used to determine the device position via a loose or tight coupling algorithm. Both algorithms iteratively linearize base station position equations around an intermediate position that changes each iteration based on VIO displacement and solves the linearized solutions until convergence. The loose coupling algorithm uses the GPS fix as an initiation position, linearizing and solving using the base station equations only. The tight coupling algorithm linearizes both the base station and GPS position equations, using an arbitrary initial position. To account for multipath effects, the linearization and solution are performed for multiple random sets of measurements and the position with the smallest error metric is selected.

Abstract: At least three different techniques are presented that facilitate cluster formation in clusterable devices such as drones. The techniques facilitate power saving in the individual clusterable devise as well as for the entirety of the cluster. The first technique utilizes a NAN application based cluster formation decision. The second technique initiates a cluster grade merging evaluation based on a “merge allowed” field in a synchronization beacon set by the discovery engine. The third technique involves a discovery engine managing cluster formation with pre-set cluster grade information.
