In one example, an antenna system is described. The antenna system includes a primary antenna on an aircraft. The primary antenna is mechanically steerable and has an asymmetric antenna beam pattern with a narrow beamwidth axis and a wide beamwidth axis at boresight. The antenna system also includes a secondary antenna on the aircraft, the secondary antenna including an array of antenna elements. The antenna system also includes an antenna selection system to control communication of a signal between the aircraft and a target satellite via the primary antenna and the secondary antenna. The antenna selection system switches communication of the signal from the primary antenna to the secondary antenna when a performance characteristic for communication with the target satellite satisfies a threshold due to a position of the aircraft relative to the target satellite.

Embodiments provide for guided alignment of the orientation of two wireless devices. A first wireless device is at a known position and a known orientation. A signal from a second wireless device is received via a plurality of receive elements of the first wireless device. The first wireless device measures phase differences of the signal at the plurality of receive elements, and determines locations of each of the second wireless device's transmit elements based on the differences. Based on the transmit element locations, and a known antenna layout of the second wireless device, an orientation of the second wireless device is determined. Based on differences between the determined orientation and the known orientation of the first wireless device, instructions for aligning the devices are generated. Once the devices are aligned, location estimates of a third wireless device are made by both the first wireless device and the second wireless device.

The described features generally relate to adjusting a native antenna pattern of a satellite to adapt communications via the satellite. For example, a communications satellite may include an antenna having a feed array assembly, a reflector, and a linear actuator coupled between the feed array assembly and the reflector. The feed array assembly may have a plurality of feeds for communicating signals associated with a communications service, and the reflector may be configured to reflect the signals transmitted between the feed array assembly and one or more target devices. The linear actuator may have an adjustable length, or otherwise provide an adjustable position between the feed array assembly and the reflector. By adjusting the position of the feed array assembly relative to the reflector, the communications satellite may provide a communications service according to a plurality of native antenna patterns.

A system includes a base station, an antenna coupled to the base station, and an antenna line device coupled to the antenna. The antenna line device is Internet Protocol (IP) addressable and is configured to receive a control signal from a controller.

Systems and methods of the present disclosure include controlling directions of communications including a processor to obtain performance data of an integrated roofing accessory installed on a roof, the integrated roofing accessory including an antenna and a transceiver to enable fifth generation cellular networking (5G) protocol communication with a 5G-enabled device, and an adjustable attachment to orient or position the antenna. The performance data is indicative of 5G signal performance between the integrated roofing accessory and the 5G-enabled device. A signal performance affecting condition is determined using the performance data, where the signal performance affecting condition is a reduced signal performance of a 5G signal beam of the antenna. An improved orientation or an improved position of the antenna is determined to remedy the signal performance affecting condition. The adjustable attachment is controlled to physically adjust he orientation of the position to achieve the improved orientation or position.
