Speakers at the 14th European Space Conference in Brussels discussed the need to defend EU assets against unfriendly attacks. Recent events in Eastern Europe would seem to lend force to such concerns, as the European Union makes headway toward the intersection of civil infrastructure and security and defense.

A factor-graph optimization-based GNSS positioning method uses GNSS pseudorange and Doppler observations to estimate position, velocity, and receiver clock biases. Added constraints on past and current graph nodes of the graph using time-difference observations of the GNSS carrier phase improve the accuracy, and a robust optimization method excludes multipath outliers. Experimental results reduce horizontal positioning error from 5 to 10 meters to 1.37 meters.
