Özet:

 Today, there are four global positioning systems GNSS that provide positioning with full capacity. These are GPS, GLONASS, Galileo and BeiDou. While GPS and GLONASS provide positioning for many years, Galileo and BeiDou have been involved in recent years. In this study, the availability status of the 1st and 2nd fundamental frequencies of these four GNSS systems was investigated. For this purpose, the data of 322 IGS stations dated 05.06.2023 all IGS stations for this date at igs.ign.fr were taken into account. According to the results, it was seen that the GPS frequency availability rates were slightly better than other satellite systems, and the availability rates were above 96. It has been determined that the availability rates in other satellite systems are above 94 except for the GLONASS second frequency.

 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 96nın üzerinde olduğu görülmüştür. Diğer uydu sistemlerinde de doluluk oranları GLONASS ikinci frekans hariç 94ün üzerinde olduğu belirlenmiştir.
