Abstract:
The hyperbolic coordinate converter converts the time difference outputs of the radio receiver into the conventional latitude-longitude coordinates and from the present position coordinates, calculates and displays the distance, bearing, and bearing error to a preselected destination along a preselected course. The development and construction of an airborne, digital, navigation computer for solving the coordinate conversion problem was proven as a result of an explicit solution to the coordinate conversion problem and some unique computing algorithms for solving trigonometric equations. The mechanization of the computer was a major breakthrough in digital computers and is now called DIVIC for DIgital Variable Increment Computer. The hyperbolic coordinate converter interfaced with an SPN-30 Loran-C Receiving Set was flight tested over the Loran-C East Coast chain. Author
