Geographic information systems (GIS)and global navigation satellite systems (GNSS) have transformed local, national and international emergencies and disasters response services. GIS/GNSS technologies offer great deal of assistance in public safety and emergency response enabling emergency management agencies to efficiently allocate resources, model risk and direct emergency response and recovery personnel. However, current GNSS-based tracking systems have serious technical flaws and vulnerabilities. This paper presents a detailed modular system-level description for a hybrid tracking system including control, space, tracking, communication, data processing, end-user and external applications segments. The paper further discusses and suggests how the technical vulnerabilities of GNSS-based tracking systems could be avoided considering hybrid tracking segment and multichannel communication paths.
