Random Optimization Algorithm on GNSS Monitoring Stations Selection for Ultra-Rapid Orbit Determination and Real-Time Satellite Clock Offset Estimation Table 3 Names and longitudes and latitudes of station selection lists for 30, 60, and 90 stations on the 68th day obtained with the probability and traditional methods, respectively. A tick indicates whether or not the station belongs to the 30, 60, or 90 set. If the longitude or latitude of a station is negative, it indicates the station locates in the western or southern hemisphere of the Earth. If the longitude or latitude of a station is a positive number, it indicates the station locates in the eastern or northern hemisphere of the Earth. It is noted that the longitudes and latitudes of some stations, such as “areg” and “areq”, are the same due to the very close distance between the stations and the rounding error of the calculation.
