Associate Professor Department of Civil Engineering, National Ilan Institute of Technology 2. Undergraduate Student Department of Civil Engineering, National Ilan Institute of Technology Abstract This study investigates the domain of position by cooporating GPS / GLONASS as well as Coop-tracking system to improve the solution rate of positioning coordinates. Moreover, for the purpose of utilizing RTK to improve the position accuracy, a test also was conducted to understand how different types of antenna influence the accurate rate. The results showed that, in the weak signal areas, utilizing Coop-tracking system is able to reduce the errors to the least. Coop-tracking system can also increase the number of tracking satellites for improving the solution rate. In other words, coop-tracking system can benefit the accuracy of solution rate. Generally speaking, it can be increased to two s
