This article discusses the role of GPS (global positioning system) systems in the command and control of multiple agencies involved in responding to a critical incident.
Abstract
GPS technology enables individuals to determine their precise location on the earth by means of devices that receive signals from a constellation of 24 satellites. This technology creates the possibility that a command post can have computer screens that graphically portray the locations of deployed resources and displays a real-time image of the scene from a satellite, albeit with a slight delay. Commanders at distant locations could view the same picture, communicate with other personnel having the same images, and coordinate strategies. In addition, if personnel are properly equipped, the incident commander can transmit information to individuals in the field, such as a picture of a wanted suspect, logistical plans of a building, or an overhead view of a disaster. This is done through a Personal Digital Assistant (PDA). Geographic Information Systems (GIS) are also a component of GPS and the command post model. This is a technology used to view and analyze data from a geographic perspective. GIS links location to information--such as the matching of people to addresses and buildings to parcels or streets within a network--and then layers that information to give the user a better understanding of how it all interrelates. Local Positioning Systems (LPS) are also part of the network for improving resource deployment. LPS requires the pre-wiring of a structure with tracking sensors, or the individuals tracked must wear tracking technology as part of their equipment. Managers can then determine locale by using receivers on location to triangulate an individuals' exact position. A case study of a GPS command post is presented.
