Description of ActivityUNMANNED systems such as Unmanned Ground Vehicles (UGVs), Unmanned Aerial Vehicles (UAVs) and Unmanned Surface Vessels rely on satellite derived information from global positioning system (GPS), and this information is crucial element for the automated operations of these unmanned systems.
Any disturbance or denial of GPS signals can dramatically impinge on the operations of an unmanned systems from the failure of the automatic identification system, electronic chart display errors, navigation system breakdowns and restriction of the capabilities of the information system which enables operational control whilst deployed.
GPS denial will also threaten the safety of their surroundings, and with recent advancements in sophisticated hacking techniques and the availability of highly efficient and computationally powerful chipsets, GPS denial will undoubtedly pose a threat to their safe operation potentially leading to loss of life.
Most of the existing research has not focussed on GPS denial for Unmanned Surface vessels mainly because of the unique technology required, which has hindered technology development compared to UAV and UGV. The challenges posed by utilisation in open seas, hostile and remote environments, positioning challenges due to lack of landmarks: all these challenges mean standard GPS denial solutions used in UAV and UGCV may not be suitable. The Institute of Industrial Research has developed an artificial intelligence (AI) based solution which address GPD denial for USVs using a positioning algorithm based on radar and satellite images to determine the USV position.
