Laser tracking system (LTS) has been widely used in energy industries to meet increasingly high accuracy requirements. However,\r\nits measuring accuracy is highly affected by the dynamic uncertainty errors of LTS, and also the current range and angle\r\nmeasurements of LTS are mainly weighted statically, obtaining the dynamic weighting model which is essential for LTS to improve\r\nthe measuring accuracy. In this paper, a dynamic weighting model that describes not only the dynamic uncertainty but also the\r\ngeometric variations of LTS is developed, which can be adjusted to the weighting factors of dynamic parameters according to\r\nthe range observations relative to the angle observations. Intensive experimental studies are conducted to check validity of the\r\ntheoretical results. The results show that the measuring accuracy of LTS has been increased 2 times after using this technique for\r\ncorrection.
