Application of Dgps/ins Integration Technique to Bushfire Monitoring

The use of wireless sensor networks for bushfire monitoring can help to map and locate fires rapidly and accurately. A Management Centre could use such information in order to deploy fire-fighters, tankers and aircraft to the best locations to protect people and communities from bushfire hazards. This paper describes an application of the GPS/INS technology to support a mobile mapping system which can be used to gather data ‘on-the-fly’ to create maps and images. A standalone GPS system cannot provide continuous positioning in difficult signal acquisition environments such as in forested areas, in urban canyons, etc. A typical scenario would involve a vehicle driving along a forest road experiencing GPS signals blockages for several minutes at a time. An integrated GPS/INS system can provide reliable, continuous and navigation solutions, even with periodic blockages of the GPS signals.
