A jobsite computer network has a local server connectable to a remote server via the internet, a network access transceiver connected to the local server, and a wireless device in wireless communication with the network access transceiver. The network access transceiver receives a message from the wireless device and sends a message to the local server. The local server utilizes information from the message to determine the location of the wireless device. The network access transceiver and/or the wireless device generate data which is sent to the remote server.

Systems and methods for inertial navigation aided by signals of opportunity (SOOP). One system includes a network operations center (NOC), a reference station, and mobile user equipment. Another system includes a NOC and user equipment without a reference station. In the latter system, the NOC comprises an antenna, a NOC receiver that generates SOOP data derived from SOOP, a computer system that generates SOOP source location/ephemeris data and inter-source clock bias data based on SOOP data generated by the NOC receiver, and a communication device to broadcast the data. The user equipment comprises an antenna, a navigation receiver that generates SOOP data derived from SOOP detected by the antenna of the user equipment, and a navigation computer system that calculates a navigation solution, including a SOOP-derived estimated position of the user equipment, based on SOOP source location/ephemeris data and inter-source clock bias data broadcasted by the NOC and SOOP data generated by the navigation receiver.

A method of determining a vehicle position and a vehicle velocity, including receiving a camera image sequence based on a camera borne by a vehicle and determining a camera pose based on the camera image sequence. The method includes determining a global position system location based on a global position system receiver borne by the vehicle, determining an inertial movement signal based on an inertial movement unit borne by the vehicle and receiving a wheel encoder signal from a wheel of the vehicle. The method additionally includes determining at least one of the vehicle positions and the vehicle velocity based on at least two of the camera pose, the global position system location, the inertial movement signal and the wheel encoder signal in temporal synchronization.

This invention refers to an innovative, original and convenient Autonomous System for Rescue operations, which works on the vessel, program controlled by a software and hardware platform rescuing people overboard in an autonomous manner. The System starts operating from the moment the person falls off the deck into the water. From the moment the wrist band on the passenger makes contact with the water, it sends out a radio frequency signal with two orders: to activate an alarm and to notify a robot to start rescue operation, and it brings it to the vessel with no intervention from people, i.e., in an intelligent and autonomous manner.
