Accuracy improvement of the map by the seamless positioning using GPS and Quasi-Zenith Satellite

第一次实验于2012年3月进行，第二次实验于2013年3月和4月进行。实验地点是位于日本中部北陆地区金泽工业大学的大千冈和Yatsukaho研究校园。实验由SPAC和JAXA支持。结果，我们得到了三个结论。(1)定点观测的LEX溶液与VRS溶液5分钟左右的观测结果没有差异，具有cm级的精度。(2)高速公路和低速步行实验虽然也受到观测环境的影响，但数据结果具有一定的准确性。(3)由于仅由QZS的一颗卫星观测，因此上升垂角与接收条件之间存在变化，但无法澄清。在2010年代末，当QZSS变成四颗卫星时，我们必须做更多的先进研究。

The 1st experiment was conducted in March, 2012 and the 2nd experiment was conducted in March and April of 2013. Location of experimentation is Ohgigaoka and Yatsukaho Research Campus of Kanazawa Institute of Technology at HOKURIKU district in central Japan. Experiments was supported by SPAC and JAXA.As a result, we got three conclusions. (1)Both of the observations of the LEX solution by the fixed point observation and a VRS solution for about 5 minutes did not have a difference, and it had accuracy of the cm class.(2) Although the experiment on the highway and the low-speed on foot were also influenced by observation environment, result of the data had an accuracy. (3)Since it was observation only by one satellite of QZS, it has variation between the ascending vertical angle and the receiving condition, but it was not able to clarify. At the end of the 2010s, by the time QZSS becomes four satellites, we have to do more advance research.
