Abstract: Structured light approaches utilize a laser to project features, which are then captured with a camera. By knowing the disparity between the laser emitter and the camera, the system can triangulate to find the range. Four, 185 degree field-of-view cameras provide overlapping views over nearly the whole unit sphere. The cameras are separated from each other to provide parallax. A near-infrared laser projection unit sends light out into the environment, which is reflected and viewed by the cameras. The laser projection system will create vertical lines, while the cameras will be displaced from each other horizontally. This relative shift of the lines, as viewed by different cameras, enables the lines to be triangulated in 3D space. At each point in time, a vertical stripe of the world will be triangulated. Over time, the laser line will be rotated over all yaw angles to provide full a 360 degree range.

Abstract: An atomic clock is used in conjunction with the GNSS receiver and the inertial sensors, creating a more capable inertial navigation system (INS). The system can be composed of a GNSS receiver, an accurate clock, and a mechanism for measuring relative pose changes. For example, the system can utilize an inertial measurement unit (IMU) to provide the relative pose changes, but other mechanisms, such as visual or LADAR odometry, can be used. The GNSS receiver measures the pseudo-ranges to the GNSS satellites in the field of view. These measurements are “time tagged” with the accuracy of the atomic clock. The relative motion between the pseudo-ranges is measured using the IMU. Finally, a lock is achieved by filtering these measurements. The filtering mechanism can be a traditional Kalman Filter or other mechanisms that attempt to minimize a mean square error.

Abstract: Atomic clocks (at both the receiver and emitter) are used to obfuscate the location of the receiver by providing a different mechanism to synchronize (other than the direct reception). Using this approach, there is no need for the emitter to emit directly to the receiver; only the reflection is necessary, and therefore, the location of the receiver (or receivers) is better obfuscated. Phased antenna arrays are used in RADAR for a variety of applications, including steering of beams and increasing the “aperture” of the antenna for Synthetic Aperture Radar (SAR). The relative position of the emitters is known by means of using a Navigation unit. The beam-steering phase shifts are dynamically computed using the position of the emitters, and the atomic clock is used to synchronize the phase shifts.

The GNSS receiver measures the pseudo-ranges to the GNSS satellites in the field of view. These measurements are “time tagged” with the accuracy of the atomic clock. The relative motion between the pseudo-ranges is measured using the IMU. Finally, the lock is achieved by filtering these measurements. The filtering mechanism can vary, from the traditional Kalman Filters to other mechanisms that attempt to minimize the mean square error.

Abstract: An after-action, mission review tool that displays camera and navigation sensor data allowing a user to pan, tilt, and zoom through the images from front and back cameras on an vehicle, while simultaneously viewing time/date information, along with any available navigation information such as the latitude and longitude of the vehicle at that time instance. Also displayed is a visual representation of the path the vehicle traversed; when the user clicks on the path, the image is automatically changed to the image corresponding to that position. If aerial images of the area are available, the path can be plotted on the geo-referenced image.
