Give a name to ESA's zone of silence
Kept isolated from the external Universe, a special ESA chamber simulates the boundless emptiness of space for testing satellite antennas. Recently refitted, it is in need of a new name. Come up with a winning ...
Catching signals from a speeding satellite
Soaring high above Earth as they speed through space, satellites are difficult targets to track. Now a new approach developed in Europe is helping ground stations to acquire signals faster and more accurately ...
Wind and weather disrupt satellite signals at high latitudes
Researchers will spend the next two years gathering meteorological data from Svalbard in the north to Nittedal in the south. The aim is to find out how much satellite signals are adversely affected by rain, ...
CYGNSS hurricane satellite mission passes key review milestone
The Cyclone Global Navigation Satellite System (CYGNSS) recently passed NASA's Systems Requirements Review and Key Decision Point-B and can now move into the next phase of development.
Inflatable antennae could give CubeSats greater reach
The future of satellite technology is getting small—about the size of a shoebox, to be exact. These so-called "CubeSats," and other small satellites, are making space exploration cheaper and more accessible: ...
