    This talk will discuss recent AFRL and university collaborations enabling cooperative navigation in GPS-denied environments for teams of fixed-wing unmanned air vehicles.  The method developed uses a tiered estimation structure. The first tier runs a high-rate front-end filter on each vehicle producing odometry-like estimates utilizing only a monocular camera and an inertial measurement unit. The second tier is a global back end, also run on each vehicle, which represents the global state of the cooperating vehicles as a pose graph using the odometry estimates from the multiple front-end filters and range measurements taken between the collaborating vehicles as inputs. The outcome is a real-time cooperative navigation capability that improves performance over the individual vehicle capabilities while requiring minimal bandwidth and providing robustness to communication dropouts.  Simulation and hardware flight-test results will be shared.
