Latest Patents

John R Selmon holds a patent for "Earth chord determination in a satellite at low spin rates." This invention involves an earth chord sensor on board a satellite that produces an electrical pulse as the satellite spins and sweeps the sensor across the earth. When the satellite operates at a low spin rate or when the sensor measures a long earth chord, the sensor generates an irregular pulse with sharp voltage peaks instead of a near trapezoidal pulse. The invention digitizes the output of the earth chord sensor, allowing a processor to analyze the digitized data through a data buffer. This process detects the leading edge peak and trailing edge peak of the pulse, enabling the calculation of the earth chord time. The calculated time is then transmitted via telemetry to a ground station for satellite positioning purposes.
