Abstract
A system may include a follower aircraft including a processor configured to: determine a follower aircraft location at a time t0; receive a real-time kinematics (RTK) update from a lead aircraft, the RTK update including information associated with: a lead aircraft location at the time t0, the lead aircraft location at a time t1 relative to the lead aircraft location at the time t0, and an object location at the time t1 relative to the lead aircraft location at the time t1; perform RTK processing to determine the follower aircraft location at the time t0 relative to the lead aircraft location at a time t0; determine the follower aircraft location at a time t2 relative to the follower aircraft location at the time t0 by utilizing time relative navigation (TRN); and determine the object location at time t2 relative to the follower aircraft location at the time t2.
