The invention provides an
algorithm for implementing global navigation
satellite system (GNSS) and WIFI
system seamless vertical handoff based on a
fuzzy neural network
algorithm in order to realize a purpose of fusing two different positioning systems mutually to implement
seamless handoff of indoor and outdoor positioning and navigation. The
algorithm comprises the following steps: acquisition of main positioning information, handoff triggering based on received signals, and handoff algorithm judgment based on
fuzzy neural network control. The algorithm for implementing the GNSS and WIFI
system seamless vertical handoff has the beneficial effect of overcoming a defect that WIFI position precision is reduced outdoor and GNSS signals have a possible of occurring interruption indoor so as to provide wrong positioning information for a user; America GPS, Russia
Glonass, EU Galileo and China Beidou
satellite have a large development on
satellite positioning and navigation application technology positioning aspects indoor, outdoor, underground, on the
earth surface and the like; and meanwhile, the algorithm provided by the invention has wide applications in the fields of national military applications, international counter terrorism, tunnel detection and the like.
