Precise orbits were obtained from the IGS (GPS) and Wuhan University (BDS). It is shown that with GPS alone the PPP solution needs on average 1 h to converge to a level of a few decimetres, whereas with BDS alone this takes on average 2.5 h, which is due to the poorer geometry of the BDS satellites in Australia. With both GPS and BDS combined this convergence time is tremendously reduced to 30 min on average. With the satellite phase biases corrected, the precision of the GPS+BDS PPP-RTK solution is at the few centimetre level.<\/p>\n<p><a href=\"https:\/\/www.researchgate.net\/profile\/Dennis_Odijk\/publication\/283668891_Multi-GNSS_PPP_and_PPP-RTK_Some_GPSBDS_results_in_Australia\/links\/56499e2b08ae54697fbe9e22.pdf\"><\/a><\/p>\n\n<div class=\"wp-block-button\">\n<a  data-e-Disable-Page-Transition=\"true\" class=\"dlm-download-link dlm-download-button wp-block-button__link wp-element-button\" title=\"\u30d0\u30fc\u30b8\u30e7\u30f3 1\" href=\"https:\/\/jsapt.net\/ja\/download\/8002\/?tmstv=1791167505\" rel=\"nofollow\" id=\"download-link-8002\" data-redirect=\"false\" >\n\t&ldquo;Multi-GNSS PPP and PPP-RTK: Some GPS+BDS Results in Australia&rdquo; \u3092\u30c0\u30a6\u30f3\u30ed\u30fc\u30c9\t<span class=\"dlm-button-meta\">56499e2b08ae54697fbe9e22.pdf\t\t&ndash; 1124 \u56de\u306e\u30c0\u30a6\u30f3\u30ed\u30fc\u30c9\t\t&ndash; 643.18 KB<\/span>\n<\/a>\n<\/div>\n\n","protected":false},"excerpt":{"rendered":"<p>Dennis Odijk\uff0cBaocheng Zhang\uff0cPeter J.G.
