Abstract: The disclosed systems for laying underground fiber optic cable may include a drive body, at least one rotational motor, a forward auger element rotatably coupled to the drive body and positioned to be rotated by the at least one rotational motor in a first rotational direction, and a rear auger element rotatably coupled to the drive body and positioned to be rotated by the at least one rotational motor in a second, opposite rotational direction. Various other systems, methods, and devices are also disclosed.

Abstract: A hybrid control algorithm for low profile phased-array antennas, consisting of a gyro control and electronic beam-forming, operates to track the satellite. The antenna arrangements form a spatial phased-array capable of being rotated mechanically both in azimuth and elevation planes by the aid of step motors. An RF detector monitors the received RF power and provides a feedback signal to the control algorithm. Based on the monitored signals, provided by RF detector and gyros, the processing unit operates, under suitable algorithms, to home on and track the desired satellite. The arrangements can be mounted on a vehicle to provide TV and broadband internet signal to the user on the move.
