To correctly fuse the measurements from multiple sensors, their time should be precisely synchronized. Aiming at the problem of multi-sensor time synchronization, this paper proposes a time synchronization algorithm based on correlation analysis between velocities or accelerations measured by different sensors. Taking the Global Navigation Satellite System (GNSS) and the inertial navigation system (INS) as experimental object, a field test was conducted to verify the performance of the proposed algorithm in a GNSS/INS integrated navigation system. The results show that the algorithm can indeed calibrate the time transmission delay or clock source inconsistency between GNSS and INS within a certain range of misalignment. The accuracies of calibration are 95.71% and 99.64% under velocities and accelerations correlation analysis, respectively.","PeriodicalId":345773,"journal":{"name":"2022 IEEE International Conference on Unmanned Systems (ICUS)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125660503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aiming at the problem of low search efficiency caused by the increase of vertex connections in the existing Visibility Graph, this paper presents a path planning algorithm based on Sparse Visibility Graph, which improves the planning efficiency of Visibility Graph by reducing the complexity of visibility graph and improving the search algorithm. Firstly, Sparse Visibility Graph construction is introduced, which reduces the complexity of the Visibility Graph by clipping unnecessary edges to reduce the degree of vertices. Secondly, the improved Lazy Theta* is introduced, the weighted valuation function is introduced to analyze the influence of the actual cost and the estimated cost on the planning effect. Aiming at the problem that the basic A * search path is constrained by the grid and the Theta* planning path is not optimal and the search efficiency is low. Through delayed the line-of-sight check and improvement in checking generations limits, the improved Lazy Theta* algorithm improves the efficiency of planning and the authenticity of the path. Finally, simulation experiments are carried out in a two-dimensional grid environment. The results show that, compared with the search algorithm based on Visibility Graph, the path planning based on Sparse Visibility Graph has a shorter search time, can achieve more efficient local path planning, and the path is more reasonable.","PeriodicalId":345773,"journal":{"name":"2022 IEEE International Conference on Unmanned Systems (ICUS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131079436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly this method obtains the distance information between nodes within the cluster through inter-UAV communication. Then the range information and part of the inertial data are used to establish the relative coordinate system and the information of the UAV centralized configuration under the relative coordinate system, and then the barometric altitude information and magnetic compass information of each UAV are used to maintain the UAV heading, altitude and cluster configuration, so as to improve the survivability of the UAV swarm in the navigation denial environment.

Then, the path planning method is developed, which can increase the global search capability by keeping population diversity with the improved Tent chaotic map, and balance the global and local searching capability through incorporating the dynamic adaptive inertia weight into the algorithm. In addition, Gaussian mutation strategy is used to increase the solution accuracy and the ability of the algorithm jumping out from the local optimum.

The cooperative target tracking problem is formulated as a multi-USV learning problem. Based on this formulation, a multi-USV distributed cooperative target tracking (MUTT) algorithm is proposed. To avoid the collisions between USVs during the tracking process, an additional safety layer is introduced. Some safety signals are constructed based on USVs' states. By correcting actions through the trained safety layer, USVs can avoid collisions reasonably. Moreover, for the sake of demonstrating the effectiveness of the proposed MUTT algorithm in target tracking, reward functions and mission scenarios are well constructed. Furthermore, a comparison of the MUTT algorithm and Multi-Agent Deep Deterministic Policy Gradient (MADDPG) algorithm is given. The obtained results manifest that the proposed MUTT algorithm provides safe policies for multi-USV cooperative target tracking tasks.","PeriodicalId":345773,"journal":{"name":"2022 IEEE International Conference on Unmanned Systems (ICUS)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115030681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
