This invention satisfies a need for surveillance of any fixed or mobile location from a 4G wireless terminal or cellular telephone equipped to view video. The surveillance device consists of digital video cameras, microphones and alarms interfacing a control unit which has the ability to time stamp and store all camera outputs on a storage device, recognize alarms, send alarm status to a remote wireless user, receive wireless calls from the remote user and act on remote commands to transmit any camera output occurring during a time period selected by the remote user. The latter will enable the remote user to document video and sound for a time interval of interest. Video and sound of this time interval may be placed in permanent storage for transfer to a portable video medium. This invention will employ the new 4G wireless network to allow a wireless terminal or telephone equipped with a video display to select the proper bandwidth needed to receive streaming video and sound from the remote surveillance device.

This invention is a method and supporting apparatus for autonomously capturing, servicing and de-orbiting a free-flying spacecraft, such as a satellite, using robotics. The capture of the spacecraft includes the steps of optically seeking and ranging the satellite using LIDAR; and matching tumble rates, rendezvousing and berthing with the satellite. Servicing of the spacecraft may be done using supervised autonomy, which is allowing a robot to execute a sequence of instructions without intervention from a remote human-occupied location. These instructions may be packaged at the remote station in a script and uplinked to the robot for execution upon remote command giving authority to proceed. Alternately, the instructions may be generated by Artificial Intelligence (AI) logic onboard the robot. In either case, the remote operator maintains the ability to abort an instruction or script at any time, as well as the ability to intervene using manual override to teleoperate the robot. In one embodiment, a vehicle used for carrying out the method of this invention comprises an ejection module, which includes the robot, and a de-orbit module. Once servicing is completed by the robot, the ejection module separates from the de-orbit module, leaving the de-orbit module attached to the satellite for de-orbiting the same at a future time. Upon separation, the ejection module can either de-orbit itself or rendezvous with another satellite for servicing. The ability to de-orbit a spacecraft further allows the opportunity to direct the landing of the spent satellite in a safe location away from population centers, such as the ocean.

Disclosed is a command planning apparatus of a low-earth orbit satellite, and a low-earth orbit satellite control system including the same. The present invention automates the process of executing the command plan for converting the satellite task schedule planned on the ground into telecommands available by the satellite in the low-earth orbit satellite control system, and automatically selects a data set established by the parameters related to the execution task of the satellite according to the mapping rule.

A system for automatic mapping of a walled structure includes at least one mobile unit, preferably worn by a user. The mobile unit has a position tracking system for tracking a current position of the mobile unit, a wall detection system including a sensor arrangement for measuring range data from the mobile unit to at least four points, and a mapping processor associated with both the position tracking system and the wall detection system. The mapping processor processes the range data and, if the at least four points lie on a common plane according to a defined criterion, maps a wall in corresponding spatial relation to the current position. The mobile unit preferably also includes a wireless communication link for transmitting and receiving data indicative of the mapped walls to other mobile units and to a remote command control unit.
