Cooperative GNSS Positioning & Navigation

Abstract:	GNSS and WiFi enabled mobile devices are becoming more and more common place with the proliferation of smartphones and the penetration of GNSS and WiFi into other common electronics such as cameras, gaming devices, etc. This is creating a new paradigm around how such devices can cooperate with each other to improve their ability to compute position and navigate. In this work, we focus on cooperation at the position-engine level and on the case when the devices’ measurements are not synchronized in time. Both simulations and experiments from live data demonstrate two general conclusions from this work: 1) a device with "strong" measurement data can help a device with “weak” measurement data to compute its position; 2) two devices with “weak” measurement data can cooperate to improve their positioning accuracy and reliability. The implications of these conclusions are that devices can cooperate to compute their GNSS locations in some harsh environments where non-cooperative GNSS receivers fail.
