Galileo technical interview with Dr. Javier Ventura-Traveset
Dr Javier Ventura-Traveset, ESA GNSS Senior Advisor and Executive Secretary of the
ESA GNSS Science Advisory Group, GSAC, European Space Agency answers our questions about GALILEO.
Galileo Atomic Clocks – Space Passive Hydrogen Masers
Space Passive Hydrogen Masers are one of the most accurate atomic clocks in the world and they are on-board Galileo satellites. The question is, why is important to be so accurate?
GPS and relativity
GPS is used every day on mobile phones, cars, trains, aircraft, … but if they just provide the device positioning on Earth why are they affected by relativity?
GLONASS overview
GLONASS is the Russian Global Navigation Satellite System (GNSS) which has been in full operation since December 1995. Today we will talk about its basic features (frequencies, codes, accuaracy,…) and we are going to also compare it slightly to the most famous one, GPS.
Egnos, the European SBAS
EGNOS is the European SBAS (Satellite-Based Augmentation System) which gives a more accuracy position than GPS. Today we bring to you its features, functionalities and applications.
GALILEO, what is it?
There exist different Global Navigation Satellite System, GPS from US, GLONASS from Russia, COMPASS from China and GALILEO from Europe. GALILEO is the newest and the one we will talk about today.
