Abstract

A self-locating remote monitoring system (750) includes a supervising base station (754) and one or more remote monitoring units (752). A remote unit (752) includes a navigational receiver (756) operating with an existing navigational system for providing a remote unit location (759) and includes a transmitter (758) for communicating the location (759) to the base station (754) for display (772). The remote unit (752) includes one or more physiological/environmental sensors (760) for monitoring at the remote location. In a specific embodiment a change in sensor status (761) results in the status and the location being transmitted to the base station (754). The base station (754) includes alarms (776) and displays (772) responsive to the change in status. One embodiment defines a man-over-board system (300) which combines water immersion (308) and distance (334) from the base station (318) to trigger an alarm (332) and begin location tracking (324). Another embodiment defines an invisible fence system (1020) which uses location (1035) and time (1039) to define boundaries for containment and exclusion. Another embodiment includes a weather surveillance radar receiver (1188) providing weather parameters (1189) within a weather region (1193) and defines a remote weather alarm system (1180). The weather alarm system (1180) uses the weather receiver (1188) to monitor weather within a defined region (1193) and to provide the base station (1184) with location (1187) and weather parameters (1199) if the parameters fall outside defined limits (1195).
