Personnel location and monitoring system

A system for geolocation in austere environments comprising:

• two or more anchors wherein each anchor includes a Global Navigation Satellite System (GNSS) receiver configured to determine an Anchor Location (AL) for each anchor, and wherein each anchor includes at least one transceiver;
• one or more Individual GeoLocation Units (IGLUs) wherein at least one IGLU is associated with a user and wherein each IGLU includes at least one Ultra-Wide Band (UWB) transceiver configured to transmit IGLU data using one or more data packets and wherein each IGLU is further associated with a Biometric Monitoring Unit (BMU) configured to measure User Biometric Data (UBD) of the user;
• and
• a base station communicatively coupled to each, wherein the base station includes a Global Navigation Satellite System (GNSS) receiver and at least one transceiver and a Location Processing Engine (LPE) configured to receive and process the IGLU data from each IGLU identifying for each IGLU an IGLU location (IL) and an IGLU position confidence, each determined by the LPE from IGLU data received from that IGLU, and wherein the base station, responsive to the IGLU position confidence of one or more IGLUs failing to exceed a predetermined threshold, modifies one or more protocols to increase IGLU position confidence of one or more IGLUs failing to exceed a predetermined threshold.

A method for geolocation of a user in austere environments, the method comprising:

• establishing a local geolocation network which includes at least one transceiver, at least one a Global Navigation Satellite System (GNSS) receiver and a base station having a Location Processing Engine (LPE);
• associating with the user an Individual GeoLocation Unit (IGLU) from among one or more IGLUs, wherein each IGLU includes at least one Ultra-Wide Band transceiver;
• transmitting by each IGLU, IGLU data using one or more data packets;
• measuring by a plurality of accelerometers motion of each IGLU;
• monitoring by a Biometric Monitoring Unit (BMU) User Biometric Data (UBD) of the user
• receiving, at the base station, IGLU data;
• determining, at the base station, an IGLU location (IL) based on received IGLU data wherein the LPE determines IGLU position confidence;
• and
• assigning, at the base station, a communication window listening for a signal from each of the one or more IGLUs and responsive to the IGLU position confidence in one or more IGLUs failing to exceed a predefined threshold, modifying the one or more protocols for the one or more IGLUs failing to exceed a predefined threshold until their position confidence exceeds the predefined threshold.
