## Abstract

A personnel location and monitoring system enables on-scene commanders in austere environments to identify, location and manage personnel. The present invention establishes a localized network of geolocation-capable transceivers which can thereafter provide communication capabilities with specially-equipped users as they ingress and egress an austere environment. Each user is equipped with an Individual Geospatial Locational Unit which provides data via a datalink with one or more of the anchors, and ultimately with a base station. From such data and the datalink itself the location of the user as well as the user's biomedical condition can be ascertained. As confidence of the location of the user drops below a predetermined threshold and/or the biomedical condition of the user raises concern with respect to the user's well-being, the present invention modifies the communication and geolocation protocols to prioritize communication and data transfer with such a user.

## Claims

### Claim 1

(canceled)

### Claim 2

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.

### Claim 3 (depends on 2)

The system for geolocation in austere environments according to claim 2, wherein each IGLU includes accelerometers configured to determine motion of each IGLU.

### Claim 4 (depends on 2)

The system for geolocation in austere environments according to claim 2, wherein each anchor includes a Global Navigation Satellite System (GNSS) receiver configured to determine an Anchor Location (AL), and wherein each anchor includes at least one transceiver.

### Claim 5 (depends on 4)

The system for geolocation in austere environments according to claim 4, wherein one of the one or more anchors is the base station and wherein each other anchor relays IGLU data to the base station.

### Claim 6 (depends on 4)

### Claim 7 (depends on 6)

The system for geolocation in austere environments according to claim 6, wherein the LPE is configured, responsive to IGLU position confidence failing to exceed a predetermined threshold, to modify a communication window for listening for signals from the one of the one or more IGLUs failing to exceed a predetermined threshold to increase IGLU position confidence.

### Claim 8 (depends on 6)

The system for geolocation in austere environments according to claim 6, wherein the LPE is configured, responsive to UBD indicating distress, to modify dwell time assignments to increase IGLU position confidence.

### Claim 9

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.
