a. GNSS-1 merupakan sistem generasi pertama dan merupakan gabungan antara satelit navigasi (GPS dan GLONASS) dengan Satellite Based Augmentation system (SBAS) atau Ground Based Augmentation System (GBAS). SBAS yang bersifat global seperti omnistar dan starfire sedangkan regional SBAS seperti Wide Area
GPS is older, more mature and have many more consumer products made for it. GLONASS and Galileo are still in the development phase, as what I know. But they are much newer and has higher accuracy. Galileo is not made mainly for military systems and are not controlled by a single country. Cara Kerja Alat Ukur GPS Geodetic. Cara kerja GPS geodetic yang pertama yaitu penentuan titik suatu posisi menggunakan GPS didasari atas satu krisis atau ikatan ke belakang pada jarak. Pengukuran yang dikerjakan secara bersamaan pada beberapa satelit yang titik koordinatnya telah dijumpai. GPS memberikan status berbentuk tiga dimensi serta bisaTwo different GPS receivers connected to the same antenna and tracking the same GPS satellite at the same time may output different C/N 0 values. If one assumes that the C/N 0 values are computed accurately by both the receivers, the differences in the C/N 0 values can be attributed to differences in the noise figure of the two front-ends and
