Personnel location and monitoring system

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

• establishing a local geolocation network by one or more anchors wherein each anchor is associated with an Anchor Location (AL) and each anchor includes at least one ultrawideband (UWB) transceiver and a Global Navigation Satellite System (GNSS) receiver and wherein one of the anchors is configured as a base station having a Location Processing Engine (LPE);
• associating with the user an Individual GeoLocation Unit (IGLU) wherein each IGLU includes at least one UWB transceiver configured to provide two-way ranging and a plurality of accelerometers configured to measure motion of the user, and wherein each IGLU associates with a Biometric Monitoring Unit (BMU) configured to measure 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 a LPE confidence in the IL;
• and
• assigning a periodic dwell time as a function of the UBD and LPE confidence in the IL.

A non-transitory machine-readable storage medium having stored thereon instructions for personnel geolocation in an austere environment, comprising machine executable code, which when executed by at least one machine, causes the machine to:

• associate with the user an Individual GeoLocation Unit (IGLU) wherein each IGLU includes at least one UWB transceiver configured to provide two-way ranging and a plurality of accelerometers configured to measure motion of the user, and to associate with each IGLU a Biometric Monitoring Unit (BMU) configured to measure User Biometric Data (UBD) of the user;
• receive, at the base station, IGLU data;
• determine, at the base station, an IGLU location (IL) based on received IGLU data wherein the LPE determines a LPE confidence in the IL;
• and
• assign a periodic dwell time as a function of the UBD and LPE confidence in the IL.
