Abstract: A low-noise amplifier (LNA) filter for use with global navigation satellite system (GNSS) devices is disclosed. A first LNA stage, which is configured to connect to an antenna configured to receive GNSS signals, includes an LNA. A second LNA stage, which is connected to the output of the first LNA stage, has a surface acoustic wave (SAW) filter and an LNA. A third LNA stage, which is connected to the output of the second LNA stage, also has a SAW filter and an LNA.

Abstract: A method for marking a point of interest in a live image on a navigation device is provided. A position of a navigation device is determined based on navigation signals received from satellites. An orientation of the device is determined based on data from an orientation sensor. A first live image is obtained from a first camera and displayed. A first marker is displayed in the first live image. The first marker indicates a first location of the point of interest in the first live image. A second live image is obtained and displayed. A second marker is displayed in the second live image. The second marker indicates a second location of the point of interest in the second live image. The first and second locations are based on the position of the device, the orientation of the device and the position of the point of interest.
