Team JURBAN has designed an efficient, long-range communications device that can fit within a 24 inch cubic enclosure. Using an inflatable dish from GATR technologies as a low-powered, high gain antenna (0 in antenna capable of a 2Mbps data link rate, with four back-up, lower data rate omnidirectional S-Band dipoles that also act as a short range communication system. The real innovation in the design is our Earth tracking algorithm and control system implementation, which uses three redundant 6 degree-of-freedom Inertial Measurement Units (IMU). These IMUs implement a quaternion math-based Kalman filter for improved stability and removes the possibility of gimbal lock, a dangerous problem which removes one degree of freedom. This had been a problem for the Apollo 11 astronauts and continues today in many engineering applications. Our solution reduces costs by greatly reducing power consumption, a difficulty in many similar systems. Furthermore, the combination of long-range communications capability, an inflatable dish, and the elimination of gimbal lock makes our device a viable solution for portable yet effective transmissions.
