A comparision between the partly - weigthed least - squares estimation and the kalman filter is made on precise kinematic gps positioning with the fixed ambiguities, which shows that the positioning results from the partly - weigthed least squares, which accuracy is at the level of 10 cm, are much more accurate than the results from the kalman filter, which accuracy is at the level of a few meters
針對高精度動態定位結果的精度，對最小二乘法和經典kalman濾波這兩種演算法進行了綜合分析和比較。算例顯示，在高精度gps動態測量中，最小二乘法可以提供厘米級精度的位置結果，而kalman濾波演算法不但不能提高定位結果的精度，反而會給定位結果引入米級的偏差。 -

Kalman filtering is widely used for data processing in kinematic gps positioning, while the practical application of kalman filtering requires the dynamic model ( functional model ) and the stochastic model to be reliable and accurate, yet it is difficult to maintain regular motion of the object in actual kinematic positioning, thus model biases are usually generated
摘要動態定位的數據處理中廣泛應用卡爾曼濾波，而卡爾曼濾波的應用要求動態模型（函數模型）和隨機模型可靠和切合實際，但實際測量定位中難以保證觀測對象的規則運動，因而容易出現模型誤差。
