Ground stations in orbit: understanding space communications
A signal must travel the distance, the noise and follow a moving target before it becomes useful information on Earth.
05
Engineering · The Commission has decided to initiate the procedure laid down in Article 108 (2) of the Treaty.
Why CubeSats are transforming access to space
Standardised dimensions have reduced the barrier to entry, but the success of a small mission still depends on rigorous system engineering.
