| 摘 要： | 通过对重力场特征参数进行研究，发现重力场特征参数曲线拐点与重力匹配有效的区域有内在联系，提出了一种基于拐点判据的重力辅助导航算法，该算法运用拐点选择和拐点扩充机制，对重力场特征曲线拐点进行选择和扩充，得到重力有效匹配区域，在惯导／重力／计程仪组合导航系统仿真机上进行仿真试验，试验结果表明：该算法能对重力匹配区域做出较好的判断，能有效提高重力辅助导航系统的精度。

| Abstract: | By analyzing gravity field characteristic parameters,the interrelationship of its inflection points and better gravity matching areas is found and a GAINS algorithm based on inflection point criterion is proposed in the paper.By virtue of inflection point choosing and expanding methods which applied in inflection points of gravity field characteristic curves,an effective gravity matching area can be obtained.The result of simulating testing based on INS/GRAVITY/DVL integrated navigation simulation system sh... |
