“…Multiple global navigation satellite systems (multi-GNSS) can improve reliability and reduce convergence time for precise point positioning (PPP) [1][2][3]. GNSS satellite orbit and clock offsets generated by precise orbit determination (POD) are prerequisite products of PPP, and their accuracy directly affects PPP performance [4][5][6].…”

The increased number of satellites and stations leads to the serious time consumption of the integrated precise orbit determination (POD), especially in the current global navigation satellite system (GNSS) with more than 120 satellites. To improve the computational efficiency of multi-GNSS-integrated POD, this paper proposed an improved parameter estimation method based on intel oneAPI high-performance computing, where the inactive parameters are eliminated in a batch mode. Compared with the classical estimation method based on the “one-by-one” elimination, the efficiencies were significantly improved with ratios of 2.53, 4.21, and 5.38 for 79, 126, and 171 stations’ GPS/BDS/Galileo/GLONASS-integrated POD, respectively. The elapsed time of the improved method by using 126 stations was the same as that of 79 stations’ POD by the classical estimation method. In terms of precision, the one-dimensional root mean square error (RMS) reductions were 0.1 cm (7%), 34.3 cm (11%), 1.9 cm (18%), 0.4 cm (8%), 0.2 cm (13%), and 0.4 cm (13%) for GPS, BDS GEO, BDS IGSO, BDS MEO, Galileo, and GLONASS satellites, respectively.

Günümüzde tam kapasite ile konum belirleme hizmeti sunan dört Küresel Konum Belirleme Sistemi (GNSS) bulunmaktadır. Bunlar GPS, GLONASS, Galileo ve BeiDou’ dur. GPS ve GLONASS uzun yıllardır hizmet verirken, Galileo ve BeiDou son yıllarda dahil olmuştur. Bu çalışmada bu dört GNSS sisteminin 1. ve 2. temel frekanslarının doluluk durumu incelenmiştir. Bu amaçla 05.06.2023 tarihine ait 322 IGS-MGEX istasyonlarına ait (bu tarih için igs.ign.fr adresindeki bütün IGS istasyonları) veriler dikkate alınmıştır. Elde edilen sonuçlara göre GPS frekans doluluk oranlarının diğer uydu sistemlerine göre bir miktar daha iyi olduğu, doluluk oranlarının %96’nın üzerinde olduğu görülmüştür. Diğer uydu sistemlerinde de doluluk oranları GLONASS ikinci frekans hariç %94’ün üzerinde olduğu belirlenmiştir.
