Abstract: A computerized positioning system is associated with a vehicle. It is configured to perform the following method: (a) receive first information indicative transmission(s), wherein the transmission is associated with an object(s). The first information comprises item(s) of object first position information associated with the object. The item of object first position information is indicative of an object absolute position. (b) receive second position information of the object, being indicative of a second relative position of the object with respect to the vehicle. (c) determine a derived position of the vehicle, based at least on the first information and on the second position information. The derived position is capable of being utilized to facilitate a correction in a reported position of the vehicle. The reported position is based on GNSS signal(s) received by GNSS receiver(s) associated with the vehicle.

Abstract: A payload elevator system and method are disclosed, configured for providing a plurality of alternative payload elevator configurations, each payload elevator configuration being configured for transporting a payload module. A composite air vehicle configuration is also provided, including a respective payload elevator configuration, the payload elevator configuration being defined by and provided by the payload elevator system, and also including at least one payload module reversibly engaged to the payload elevator configuration via a corresponding engagement and release system.
