[null,null,"V2.1.03","2005-04-29","完善手机移动方向预测代码，并将预测方向应用到二维定位中，并且利用预测方向修订第一径；修改信号同步模块中的设计缺陷，解决轨迹跳变问题，改善定位效果；修改了1维定位时检查定位点是否在矩形框内的外延量，从3米修改为了5米。"]
[null,null,"V2.1.04","2005-05-08","完善toa模块代码，10秒钟后开始启用toa模块，之后每5秒统计一次toa偏移量，若前后两次偏移量小于门限值则后面5秒则用toa模式选择极小值点，反之则用tdoa。增加贝塞尔曲线插值，在当前点和上一个点之间插入3个点，以平滑曲线，并且实现每秒输出4个点的效果。发布V2.1.04版本。"]
