摘要
针对文献中定位方法的弱点,提出了一种通过道路宽度进行强制约束的松驰解法。该方法不仅能提高高等级道路上用户的定位精度,而且在保证方差最小的情况下,使用户总被限制在道路上。
Being aimed at the weaknesses in paper[1],a slack positioning method of geostationary satellite positioning based on road is given. Using the width of road to confine the user's position, this method not only improves the position precision of users which are on the high rating roads, but also alwarys restricts the user's position on the roads while the variance is mosthy limited.
