Wi-Fi for Assured PNT and Integrity Verification
It is common for a group of GPS users to have the need to operate in close proximity in a denied or degraded GPS environment. Using the traditional GPS receiver approach, individual or all users may be denied the ability to navigate in such an environment, even though each user may be intermittently receiving useful satellite signal information. Collectively, the network of GPS users may be able to receive sufficient satellite signals, augmented by intra-network Wi-Fi ranging measurements, in order to form a joint position determination. This Phase I research offers an opportunity to explore the potential benefits, driving issues, pitfalls, and integration challenges of Wi-Fi augmentation of GPS.
