Navigational and location determination system

A system comprising:

• a sensing/pointing device (SPD) formed with a pointing alignment structure;
• a laser range finder coupled with the SPD aligned with the pointing alignment structure;
• a display disposed into the SPD that displays a plurality of graphical user interfaces;
• a communications device that remotely communicates output to remote operator resulting in situational awareness (SA);
• an inertial navigation unit (INU) comprising an inertial measurement unit (IMU) placed into a strap down configuration within the SPD comprising three axis accelerometers, three axis gyroscopes, with an x-axis of the accelerometer and gyroscope axis aligned with the alignment structure and the laser range finder's pointing axis, said INU further includes a global positioning system (GPS);
• a machine readable storage medium that stores a plurality of machine readable instructions;
• a processor coupled within the SPD in communication with the INU and laser range finder (LRF) which is configured to read the plurality of machine readable instructions and data structures stored in the machine readable recording medium;
• and
• a control section including a trigger or control that receives an activation input from a user which activates the LRF to determine distance to a target when the user points the alignment structure at a target;
• wherein said plurality of machine readable instructions comprises:
• a plurality of machine readable instructions comprising a first plurality of machine readable instructions that operates the INU, IMU and GPS;
• a second plurality of machine readable instructions configured to generate a three axis x, y, and z data model;
• a third plurality of machine readable instructions that creates a three dimensional georeference map model comprising latitude and longitude information overlaid over terrain that the SPD is traversed over;
• a fourth plurality of machine readable instructions that selectively starts recording latitude and longitude data of the SPD at a plurality of stored location points starting at an initial location point selected by the user using the control section or the graphical user interface along a displacement path that the user carrying the SPD passes over ending in a final location point;
• a fifth plurality of machine readable instructions that receives a remote georeference determination activation from the control section, or graphical user interface or switch which activates the laser rangefinder to obtain a target distance measurement between the SPD and the target at the final location point and determines a path line between the initial location point and the final location point then selects and stores a line of longitude from the map model which passes through the path line as a selected line of longitude data;
• a sixth plurality of machine readable instructions that rotates rotational matrix so that it rotates axis data to rotate/align the z axis based on inputs from the IMU including z axis IMU sensor output detecting gravity to rotate the x, y, and z to co-align respective z-axis;
• a seventh plurality of machine readable instructions that rotates or aligns the RFM y axis with the with the selected line of longitude data;
• a seventh plurality of machine readable instructions that aligns the x axis of the RFM with the laser range finder axis as it points at the target at the final location point;
• an eighth plurality of machine readable instructions that remotely determines the target's latitude, longitude and elevation based on target distance measurement, the final location point, and the three axis that has been aligned with detected gravity, the selected line of longitude, and the laser range finder's axis that was pointing at the target at the final location point;
• and
• a ninth plurality of machine readable instructions that determines an error value of the position of the target;
• and
• a tenth plurality of machine readable instructions that displays:
• distance and heading traveled from starting point to AP, AP's location, LRF range, bearing and elevation from AP to target, and target's latitude, longitude, elevation, and location error;
• and
• an eleventh plurality of machine readable instructions that communicates distance and heading traveled from starting point to AP, AP's location, LRF range, bearing and elevation from AP to target, and target's latitude, longitude, elevation, and location error to remote user for situational awareness (SA).
