GLONASS

Sejumlah[pranala nonaktif permanen] satelit navigasi yang diluncurkan pada tahun 2014

GLONASS (bahasa Rusia: ГЛОНАСС, IPA: [ɡɫɐˈnas]; bahasa Rusia: Глобальная навигационная спутниковая система, tr. Global'naya Navigatsionnaya Sputnikovaya Sistema), atau "Sistem Satelit Navigasi Global", adalah sistem navigasi satelit berbasis ruang angkasa yang beroperasi di radionavigasi-satelit.

Sistem ini memberikan alternatif untuk GPS dan merupakan sistem navigasi kedua yang beroperasi dengan cakupan global dan presisi yang sebanding.

Kontrol darat

Segmen kontrol darat GLONASS hampir seluruhnya terletak di bekas wilayah Uni Soviet, kecuali beberapa di Brasil.

Segmen tanah GLONASS terdiri dari:

  • Pusat kendali sistem;
  • Lima Telemetri, Pusat Pelacakan dan Komando;
  • Dua Stasiun Laser Ranging; dan
  • Sepuluh Stasiun Pemantauan dan Pengukuran.
