Publication number: 20240094681Abstract: A time transfer method based on undifferenced and uncombined PPP-RTK is applied to a time transfer system including a PPP-RTK network end observation station network and PPP-RTK user end observation stations. The network end observation station network includes GNSS reference stations and a network data processing center. The user end observation stations include a time reference station and an ordinary user station. The method includes: acquiring GNSS observations collected by the GNSS reference stations and performing an undifferenced and uncombined PPP-RTK resolution to generate network end products; each of the user end observation stations performing an undifferenced and uncombined PPP-RTK resolution by using collected GNSS observations and the network end product to generate multi-GNSS receiver clock biases; and solving a combined inter-station clock bias by using the receiver clock biases of the ordinary user end observation stations and those of the time reference station serving also as user end.Type: ApplicationFiled: February 7, 2023Publication date: March 21, 2024Inventors: Kan Wang, Baoqi Sun, Xuhai Yang
