GNSS based relative navigation for intentional approximation of aircraft
In aviation, satellite navigation is generally only used to determine the absolute position of aircraft. We show that the signals can also be used for safe relative navigation provided that a data link exists between the two aircraft.

Research on Relative Navigation Source Selection in Peer-to-Peer Structure [PDF]
On the basis of centralized structure and distributed structure, the model based on peer-to-peer structure is established. Aimed in the problem of source optimal selection for passive location relative navigation under peer-to-peer structure, the Gauss ...

Multi-Slots Joint MLE Relative Navigation Algorithm Based on INS/JTIDS/BA for Datalink Network
High accuracy relative navigation (RELNAV) information is crucial for datalink network members in the situation of joint operations, especially the situations that some datalink network members may not be able to obtain their location with absolute ...

Relative navigation and control of a hexacopter
This paper discusses the progress made on developing a multi-rotor helicopter equipped with a vision-based ability to navigate through an a priori unknown, GPS-denied environment. We highlight the backbone of our system, the relative estimation and control.
