... 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...
... 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...
...-as-a-service and mission-as-a-service A solution to this challenge involves using a shared-access, single host/multi-tenant satellite. This approach can dramatically lower costs and speed up the development schedule of many areas of space technology...
... 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...
... The types of data incorporated into the system include: Open and proprietary vessel tracking telemetry Satellite-based RADAR observations Satellite-based optical and near-infrared imagery Unmanned aerial, surface or underwater vehicle sensors Global...
... 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...
