Abstract
Precise point positioning is a GNSS based positioning method that is known to regaining more precise information about major systematical errors in its functional model. This method is seen as an advanced version of the conventional absolute positioning method that is able to offer higher accuracy of the estimate parameter. Contrarily, the relative positioning method is able to achieve high precise of the estimated parameters by using two or more receiver. Consequently, it utilizes more resources in performing observation. Hence, this contribution attempts to explore some considerable aspects that can make the PPP method has a comparable precision of the National Standard of Horizontal Reference Network (SNI JKH). Based on the experiments, with data rate of 0.03 Hz for GPS and GLONASS observation shown that result of the PPP method is comparable to the relative method, whenever the observation is performed in minimum duration of six hours. Moreover, the 3th order of accuracy can be achieved after a demanding observation period, depends on processing strategy.
Highlights
Precise point positioning (PPP) is an advanced version of the conventional GNSS-based absolute positioning
The result of PPP method on ITN1 station is more accurate than CLBG station because of field condition in ITN1 is widely open than CLBG
If the absolute error ellipse of PPP method is lower than the value above, it means that the PPP method reaches the 3rd order of horizontal position
Summary
Precise point positioning (PPP) is an advanced version of the conventional GNSS-based absolute positioning. The quality of PPP method depends on its ability to eliminate the observation related errors This contribution focuses on the minimum observational duration that is required to fulfill a certain level of accuracy standard. Relative positioning method requires more effort by using two or more receivers with one of receiver acting as a reference station This method eliminates the observation errors with double difference technique. The experiments expect to fulfill the 3th order of the Indonesia National Standard of horizontal reference network (SNI JKH). This contribution attempts to investigate some considerable aspects that can make accuracy of the PPP method is comparable to the accuracy of relative positioning method
