BITAN-II（BITAN：北航惯性地形辅助导航算法的缩写）是一种利用卡尔曼滤波理论估计惯导系统位置误差和速度误差的地形辅助导航算法。与BITAN相比，BITAN-II的独特之处在于其采集方式，采用一组单态卡尔曼滤波器来间接校正INS的位置误差，另一个特点是BITAN-II总体结构的改进。蒙特卡罗模拟表明，BITAN-II 提供了更高的定位精度，同时保留了更高的抗误定位能力。
BITAN-II ( BITAN: the abbreviation of BUAA Inertial Terrain Aided Navigation Algorithm) is a type of terrain aided navigation algorithm using the Kalman filtering theory to estimate position errors and velocity errors of the INS. Compared with BITAN, the unique feature of BITAN-II lies in its acquisition mode, which employs a bank of one state Kalman filters to correct the position error of INS indirectly, another feature is the improvement in BITAN-II's general structure. Monte Carlo simulations indicate that BITAN-II provides a higher accuracy of position fix while retaining higher immunity to false fixes.
