A method includes implementing, via an electronic controller of an aircraft, an extend command received by the electronic controller from a flight control computer to rotate a wingtip of a wing to a flight position. The method includes, in response to a first determination at the electronic controller that rotation of the wingtip stopped before the flight position during implementation of the extend command, sending a first notification signal to the flight control computer from the electronic controller to cause the aircraft to be grounded and to schedule maintenance of the aircraft. The first notification signal includes one or more first error codes. The first notification signal causes the maintenance to include wingtip-to-latch pin drop maintenance responsive to a determination of the electronic controller indicating that a first particular angle of the wingtip relative to a primary portion of the wing is in a latch pin interference range.

Satellites may communicate using an optical communication system that provides high bitrate communication while also facilitating tracking, ranging, and low bitrate communication. Light modulated with a high bitrate signal is also modulated to include a set of orthogonal tones used for tracking, ranging, and low bitrate data. A continuous tracking tone may be sent to facilitate acquisition and tracking at the receiver. Timing signals may be exchanged using the tones. These may be used to calculate range between the satellites or provide precision time synchronization. One or more of these tones may be modulated to send low bitrate data. At the receiving device, the incident light may be detected by a first detector with a wide field of view, such as a quad cell detector, and the tones detected. With tracking established, the incident light is directed on a second detector and the high bitrate signal is detected.
