Abstract: A GNSS smart antenna system includes an antenna, a processor and a receiver combination unit adapted for economical construction and enhanced performance when performing differential guidance operations. The antenna unit includes a dual frequency antenna, a dual frequency receiver unit, dual processors, and a radio bay for receiving a radio device. Rover and base smart antenna units are interchangeable in the system.

Abstract: An antenna alignment and monitoring system is provided for telecom antennas and includes a pair of global navigation satellite system (GNSS) antennas mounted on a printed circuit board (PCB) for installation in a telecom antenna enclosure. Multiple telecom antennas are configured in an antenna array for mounting on a transmission tower or other elevated structure. A common GNSS receiver cycles among the GNSS antenna pairs for initially aligning and subsequently monitoring the azimuth alignment of the telecom antennas relative to a reference azimuth using GNSS triangulation.

Abstract: A tightly-coupled printed circuit board (PCB) circuit includes components mounted on a PCB enabling smaller integrations using decoupled lines extending between reference layers, such as ground planes, form isolation islands on the PCB. The decouplers are capacitors, inductors and/or resistors in tandem with ground layers of the PCB. The isolated components can comprise high-frequency RF antennas and receivers, for example in a GNSS antenna-receiver circuit. Multiple antennas can be connected to one for more receivers with multiple, independent RF front end components by RF traces, which are either embedded within the PCB between the ground planes, or by surface microstrip antenna traces.
