Abstract: A global navigation satellite system (GNSS) receiver including an antenna module configured to removably attach to a receiver module. The antenna module includes an antenna configured to receive wireless signals transmitted by a GNSS satellite. The antenna is coupled to a wired connection. The antenna module also includes an antenna-side radio that is coupled to the wired connection. The antenna-side radio is configured to perform actions including sending, via the wired connection, an identifying signal to a receiver-side radio. The identifying signal includes identification information corresponding to the antenna. The receiver module includes the receiver-side radio coupled to the wired connection. The receiver-side radio is configured to perform operations including receiving, via the wired connection, the identifying signal from the antenna-side radio. The receiver module also includes a radio frequency (RF) front end coupled to the wired connection.

Abstract: An apparatus is provided to effectively reduce the non-active detection gap between sensor elements of an optical sensor. Reducing the non-active gap can subsequently reduce the time delay between sensor elements, mitigating the image degrading effects of a composite element time delay. While applicable to use with a wide range of optical sensors, the invention may be used for detecting aspects of a variable-rate dynamic colorful object using a matrix sensor or a tri-linear color CCD sensor. In one variation, optical fibers extend from a first fiber optic faceplate to a second fiber optic faceplate. The optical fibers can be oriented toward or directly mounted to the sensor elements. A spacer may be used to separate the optical fibers for alignment with the sensor elements and the other end of the optical fibers are attached to each other.

Abstract: An antenna comprises a signal radiator, a ground plane spaced apart from the radiator, and a dielectric separator between the radiator and the ground plane. The separator comprises at least two positions having different dielectric constants. In a preferred embodiment, it comprises a material such as FR-4 that has a dielectric constant and a loss tangent substantially higher than those of air and is formed with at least one void reducing the loss tangent of the separator. The antenna strikes an effective compromise between the dielectric constant and loss tangent and is well suited to transmit and receive GPS signals.
