Title: The Innovations of Marvin R Wachs
Introduction
Marvin R Wachs is a notable inventor based in Calabasas, CA (US). He holds a total of 10 patents that showcase his contributions to the field of satellite communication systems. His work has significantly advanced the technology used in communications satellites.
Latest Patents
One of his latest patents is titled "Access control for multi-access satellite communication system." This innovative system and method restrict access to a satellite repeater transponder by utilizing a pseudo-random noise generator. This technology automatically modulates a local oscillator around a nominal frequency during frequency translation within the satellite transponder. The carrier signals of authorized user terminals are modulated with a matching or inverse noise waveform produced by the pseudo-random noise generator. This ensures that the noise signal modulated onto the carrier signal will only be canceled out in authorized transmissions. Consequently, unauthorized user terminals are unable to recover the baseband signal due to insufficient carrier-to-noise ratio in the expanded bandwidth created by the pseudo-random frequency modulation.
Another significant patent is the "Communications satellite interference location system." This system and method determine the location of a source of interference for a communications satellite. It features an antenna array located on the earth-facing panel of the communications satellite. The method determines the direction of a source of interference relative to the satellite's own coordinate system. The angle of arrival of the interference signal is determined concerning the horizontal and vertical baselines of the coordinate system by comparing the outputs of the appropriate antennas in the antenna array.
