Introduction: FORWARD is a free NGS software designed to take a set of coordinates and an azimuth and distance from those coordinates to a new point and provide the coordinates of the new point. This is mainly useful in finding an azimuth mark from a triangulation station or occasionally vice versa. In a triangulation station's datasheet, the box score will usually have the azimuth and distance from the main station to the azimuth mark. Since the distance to measure will generally be several hundred feet or more, it is more practical to use a GPS receiver to get close to the azimuth mark's position. Use FORWARD to calculate coordinates of the azimuth mark from the box score's data. When using a magnetic compass, be sure to correct for declination.

Usage Notes: Start FORWARD, select option 1, enter the latitude, then the longitude of the starting point (station). Then enter the azimuth and distance to the end point. The program will then give the coordinates of the end point.
