Paper Abstract

Ashtech Solutions and TEQC are the software for GNSS data processing. One common function for both software is translating binary data received by Ashtech receiver to standard RINEX format. Difference in centimeter between the RINEX data translated by them is found in this paper. Moreover, the multi-path of the RINEX data translated by TEQC is much more serious than that by Ashtech Solutions. The reasons caused large differences are analyzed in the paper, and in our opinion, Ashtech Solutions smoothes the data during translating. Unfortunately, general users not only do not know the default option of smooth, but also can not modify it. As it is well known, any correction should be avoided when checking the quality. Otherwise, pseudo-results are obtained. Thus, it is not suitable to check the quality of a site with the data translated by Ashtech Solutions. Nowadays, as there are so many different GNSS random processing software, we have to be careful when using them.
