The challenges of satellite communications on the move
... antenna beams. Instead of a parabolic dish that is mechanically rotated in azimuth and elevation to maintain beam-pointing at the satellite, electronic antennas are being developed. Electronic beam steering can do this without moving parts and can...

Urgent action needed to keep satellites safe in orbit
... tool to allow the exchange of information, we still need to develop additional sources for the information that is to be exchanged. A satellite that is not properly disposed of only becomes a new element of the debris picture While there may exist...

Climate monitoring and the need for open access to global environmental satellite data
... still exacerbated by a lack of international data sharing. While some nations make data from unclassified, government-owned EO satellites freely available, others still restrict access, which means that not all collected data is contributing to our...

Flouting the rules on satellite registrations
... using foreign rockets, was accidentally omitted. Similarly, registration of the short-lived STS-44, SEDS-1 and STS-66 satellites were omitted by error. The registration information of 1991-1A initially included the USA as the territory of launch and...

Monitoring marine litter by satellite
... The key requirement for this technique is spatial resolution and the best resolution achievable by non-military satellite is currently 25-30 cm. This limits the application of the technology to ML items with a size on the same order of magnitude for...
