Multi-GNSS combined PPP has become a hot topic in recent years with the development of multiple GNSSs. Meanwhile, with the operation of the real-time service (RTS) of the International GNSS Service (IGS) agency that provides satellite orbit and clock corrections to broadcast ephemeris, it is possible to obtain the real-time precise products of satellite orbits and clocks and to conduct real-time PPP. In this contribution, the real-time multi-GNSS orbit and clock corrections of the CLK93 product are applied for real-time multi-GNSS PPP processing, and its orbit and clock qualities are investigated, first with a seven-day experiment by comparing them with the final multi-GNSS precise product \u2018GBM\u2019 from GFZ. Then, an experiment involving real-time PPP processing for three stations in the Multi-GNSS Experiment (MGEX) network with a testing period of two weeks is conducted in order to evaluate the convergence performance of real-time PPP in a simulated kinematic mode. The experimental result shows that real-time PPP can achieve a convergence performance of less than 15 min for an accuracy level of 20 cm. Finally, the real-time data streams from 12 globally distributed IGS\/MGEX stations for one month are used to assess and validate the positioning accuracy of real-time multi-GNSS PPP. The results show that the simulated kinematic positioning accuracy achieved by real-time PPP on different stations is about 3.0 to 4.0 cm for the horizontal direction and 5.0 to 7.0 cm for the three-dimensional (3D) direction.<\/jats:p>","DOI":"10.3390\/rs10020337","type":"journal-article","created":{"date-parts":[[2018,2,23]],"date-time":"2018-02-23T17:41:40Z","timestamp":1519407700000},"page":"337","source":"Crossref","is-referenced-by-count":59,"title":["Validation and Assessment of Multi-GNSS Real-Time Precise Point Positioning in Simulated Kinematic Mode Using IGS Real-Time Service"],"prefix":"10.3390","volume":"10","author":[{"given":"Liang","family":"Wang","sequence":"first","affiliation":[{"name":"Academy of Opto-Electronics, Chinese Academy of Sciences, No.9 Dengzhuang South Road, Haidian District, 100094 Beijing, China"},{"name":"University of Chinese Academy of Sciences, No.19A Yuquan Road, Shijingshan District, 100049 Beijing, China"}]},{"given":"Zishen","family":"Li","sequence":"additional","affiliation":[{"name":"Academy of Opto-Electronics, Chinese Academy of Sciences, No.9 Dengzhuang South Road, Haidian District, 100094 Beijing, China"}]},{"given":"Maorong","family":"Ge","sequence":"additional","affiliation":[{"name":"German Research Centre for Geosciences (GFZ), 14473 Potsdam, Germany"}]},{"ORCID":"http:\/\/orcid.org\/0000-0001-7241-0656","authenticated-orcid":false,"given":"Frank","family":"Neitzel","sequence":"additional","affiliation":[{"name":"Institute of Geodesy and Geoinformation Science, Technische Universit\u00e4t Berlin, 10623 Berlin, Germany"}]},{"given":"Zhiyu","family":"Wang","sequence":"additional","affiliation":[{"name":"Academy of Opto-Electronics, Chinese Academy of Sciences, No.9 Dengzhuang South Road, Haidian District, 100094 Beijing, China"},{"name":"University of Chinese Academy of Sciences, No.19A Yuquan Road, Shijingshan District, 100049 Beijing, China"}]},{"given":"Hong","family":"Yuan","sequence":"additional","affiliation":[{"name":"Academy of Opto-Electronics, Chinese Academy of Sciences, No.9 Dengzhuang South Road, Haidian District, 100094 Beijing, China"}]}],"member":"1968","published-online":{"date-parts":[[2018,2,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"5005","DOI":"10.1029\/96JB03860","article-title":"Precise point positioning for the efficient and robust analysis of GPS data from large networks","volume":"102","author":"Zumberge","year":"1997","journal-title":"J.
