Techniques for differentiating orthogonally modulated symbols from different transmitters using one or more antenna arrays are described. According to some techniques, symbols received at one or more antenna arrays are grouped together by matching respective sets of receive beams for each symbol. In this manner, symbols received from a first transmitter at a first location can be differentiated from symbols received from a second transmitter at a second location, and both sets of symbols can be successfully decoded. When the symbols are received using frequency hopping, the receive beams for each symbol can be sorted according to path length, which improves performance, and also enables precise location of the transmitter(s).

This present disclosure describes techniques for a satellite core network to relay user plane data to a recipient device. An orchestration controller on the satellite core network is described that is configured to receive an indication that the satellite core network has received user plane data for transmission to a recipient device, detect a constellation of secondary LEO satellites to transmit the user plane data to the recipient device, and select an initial LEO satellite to relay the user plane data to the recipient device.

A satellite having a set of antenna elements with predefined directions and beam angles is described. This satellite may dynamically select at least a given antenna element based at least in part on utilization and/or availability of a terrestrial wireless communication network used by an electronic device that communicates with the satellite. Moreover, the satellite may change its attitude based at least in part on the given antenna element, where the changed attitude positions a region in a predefined beam angle of the given antenna element. The satellite may dynamically select the region to which it transmits wireless signals. For example, the region may be selected based at least in part on weather conditions associated with the region and/or priority of content conveyed by the wireless signals. Alternatively, the satellite may receive information specifying the region, the utilization and/or the availability of the terrestrial wireless communication network in the region.

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.
