摘要： An antenna alignment apparatus may include magnetic field sensors as an alternative to or in addition to GNSS sensors. The magnetic field sensors may measure the earth's magnetic fields at corresponding locations, and a processor may use the measurements to calculate at least one of a roll, tilt, or azimuth of an antenna. A declination based on GNSS based alignment and magnetic field sensor alignment may be stored for an adjustment of magnetic field sensor based azimuth calculations. For an optical alignment, the antenna alignment apparatus may, additionally or alternately, include a reference object (e.g., a printed mark or a physical stud) located within a field of view of a camera. A location of the reference object may indicate the alignment of the antenna vis-à-vis the structures within the field of view.

摘要： An antenna alignment device includes an embedded (or is connected to) direct current (DC) voltmeter. In addition to using different sensors for azimuth and tilt alignment of an antenna, the DC voltmeter may be used to measure the DC voltage indicative of received signal strength at the antenna. The received signal may have a transmission pattern generated by a far side antenna. Particularly, the DC voltmeter may be used to detect peaks in the DC voltage and count the number of detected peaks as the antenna is moved changing its azimuth and the tilt. An odd number of peaks indicates the boresight of the antenna is in the main lobe of the transmission pattern, and an even number of peaks indicates otherwise. The highest peak in the odd number of peaks corresponds to the main lobe and the boresight of the antenna is aligned/tuned toward the highest peak.

摘要： An antenna alignment device may have a camera that takes a line-of-sight image. For an antenna alignment device directed to a boresight of an antenna, the line-of-sight image is the “view” from the antenna to the surrounding environment. An antenna radiation pattern, based on the antenna type, may be overlaid on the line-of-sight image. A technician and or other user can therefore observe the radiation pattern vis-à-vis the surrounding environment. Therefore, it can be determined during the initial alignment stage, whether the antenna alignment may have to be changed to account for structures and or other blockages in the surrounding environment rather than just relying antenna alignment based on an ideal model site. The overlaying also speeds up troubleshooting as it can be used to provide clear and specific alignment instructions prior to deploying crew to the antenna site.
