Systems and methods for remote navigation

A system comprising:

• one or more aiding sensors onboard a vehicle;
• an inertial measurement unit (IMU) onboard the vehicle and operative to produce inertial measurements;
• a strapdown inertial navigation system (INS) onboard the vehicle and configured to receive the inertial measurements from the IMU, the strapdown INS configured to compute estimated kinematic state statistics of the vehicle;
• at least one processor operatively coupled to the one or more aiding sensors and the strapdown INS, the at least one processor hosting a feature extraction module, an association module in operative communication with the feature extraction module, and a map features module in operative communication with the association module;
• an onboard navigation filter in operative communication with the association module and the strapdown INS;
• and
• an onboard transmitter/receiver in operative communication with the strapdown INS;
• wherein the feature extraction module is operative to extract sensor-based features from sensor measurements provided by the one or more aiding sensors;
• wherein the map features module is operative to store map-based features of a local map received by the vehicle from a remote command center;
• wherein the association module is operative to associate the sensor-based features from the feature extraction module with the map-based features from the map features module to identify position vectors in the local map that are sent to the navigation filter for further processing to provide aided navigation of the vehicle.
