Hace 1 día · An antenna tuner is a passive electronic device inserted between a radio transmitter and its antenna. Its purpose is to optimize power transfer by matching the impedance of the radio to the signal impedance on the feedline to the antenna.
Hace 3 días · Use the following diagram as a reference to compare with your own antenna installation. 2. The position of the antenna mounting is crucial for an optimal performance of the GNSS receiver. When using patch antennas, the antenna plane should be parallel to the geographic horizon.
Hace 2 días · Sea level monitoring is an essential foundational project for studying global climate change and the rise in sea levels. Satellite radar altimeters, which can sometimes provide inaccurate sea surface height data near the coast, are affected by both the instrument itself and geophysical factors. Buoys equipped with GNSS receivers offer a relatively flexible deployment at sea, allowing for long ...
Hace 5 días · We propose an efficient offline pointing calibration method for operational antenna systems which does not require any downtime. Our approach minimizes the calibration effort and exploits technical signal information which is typically used for monitoring and control purposes in ground station operations.
Hace 4 días · Survey multiband GNSS antenna, calibrated by NGS, with TNC connector and 1.5m rugged cable terminated with SMA male. Ideal for surveying applications including PPK and post-processing. – Compatible with all simpleRTK2B boards as well as any other multiband GNSS receiver in the market.
Hace 12 horas · A common application is the waveguide between a calibration assembly and the wheelhouse antenna in a surface vessel. It is important here that there be shielding of the signal waves within the conducting waveguide used, and the TE mode is less attenuative upon wave penetration of a conductive surface than the TM mode.
