Latest Patents

Jackson Ma holds a patent for a "Flexible digital ranging system and method." This invention encompasses systems and methods that determine the distance between an orbiting satellite and a ground station. The technology involves a master clock divider circuit that generates clock signals derived from a master clock. Additionally, a transmit code generation circuit produces pseudo-random number codes, which are processed to create a composite signal with positive and negative correlation peaks. This signal is transmitted to the satellite as an analog signal. A digitizing circuit then receives and digitizes this analog signal. The invention also includes a frequency domain matched filter that match filters the digitized signal to produce correlation peaks. A central processing unit utilizes software matched filters to compute the distance from the ground station to the satellite by calculating the time difference between the transmission and reception of the composite signal, divided by the speed of light.
