CLIF: Cross-layer LEO-ISL Fingerprinting for Physical and Network Attack Detection in Dense LEO Constellations
new Abstract: Low-Earth Orbit (LEO) mega-constellations such as Starlink by SpaceX and Kuiper by Amazon rely on optical Inter-Satellite Links (ISLs) for autonomous mesh routing to provide low-latency telecommunication, Internet of Things (IoT), and security services globally. As commercial operators and governments deploy increasingly dense constellations and form multi-operator peering coalitions, ISL integrity becomes critical to both commercial availability and national security. However,...

Collaborative Space Object Detection with Multi-Satellite Viewpoints in LEO Constellations
Announce Type: new Abstract: With the growing number of satellites in low Earth orbit (LEO) constellations, the near-Earth space environment has become increasingly congested, making space object detection (SOD) a pressing challenge for space safety and sustainability. To mitigate collision risks and ensure the continuity of space operations, SOD systems must deliver fast and accurate detection under stringent onboard constraints. In this paper, we investigate the potential of...
FCC lifts looming deadline for Amazon Leo satellite broadband constellation
The Federal Communications Commission has waived a requirement for Amazon to launch half of its satellite broadband constellation by the end of July, a key regulatory reprieve that buys the tech giant time to get more of its spacecraft into orbit. Amazon won regulatory approval for the Amazon Leo network in July 2020. The FCC's authorization came with two deadlines.

Mapping the Storm: Geospatial Impacts of Severe Weather on LEO Network Performance
Announce Type: cross Abstract: LEO satellite constellations, led by deployments such as Starlink, are playing an increasingly pivotal role in enabling global broadband connectivity. However, the reliability and performance of these space-based networks are highly sensitive to environmental dynamics, particularly localized weather phenomena that exhibit strong spatio-temporal variability. In this study, we present a continental-scale geospatial analysis of weather-induced performance...
Amazon Leo's satellite homework is late, but FCC won't flunk it just yet
Amazon is set to miss its deadline to deploy half of its Leo satellite constellation by July 30, as required by the Federal Communications Commission (FCC). The agency has, however, granted it a waiver of sorts – at the cost of priority status in spectrum licensing. The Bezos-founded behemoth got the go-ahead from the FCC for what was then known as Project Kuiper back in 2020.
Blue Origin explosion is a major setback for NASA’s Moon plans and Amazon’s Starlink competitor
New Glenn rocket explodes at Launch Complex 36 on Thursday night in Florida. | Image: Spaceflight Now While Blue Origin investigates the root cause behind last night's spectacular explosion of its New Glenn rocket, it's already clear that this will be a major setback for NASA's Moon base plans and Amazon's fledgling Leo space internet constellation. The incident occurred at about 9pm at Blue Origin's Florida launch site during a hot-fire test, where seven engines in the booster stage are lit...
FCC relaxes Amazon's satellite internet deadline
FCC relaxes Amazon's satellite internet deadline The retailer had until July 30 to launch 1,600 satellites, but won't have the rocket capacity in time. The US Federal Communications Commission (FCC) has granted Amazon an extension on its Leo satellite internet deployment, according to a ruling released on June 5.
Musk's Starlink leads Bezos' Amazon as airlines rush to boost in-flight Wi-Fi
Musk's Starlink leads Bezos' Amazon as airlines rush to boost in-flight Wi-Fi RIO DE JANEIRO, June 9 : Global airlines' push to attract premium customers is making fast in-flight Wi-Fi an increasingly important perk, turning a once-patchy paid service into an emerging battleground between Elon Musk's Starlink and Jeff Bezos' Amazon Leo satellite network. Starlink, which operates around two-thirds of all satellites in space and is the major driver of revenue for SpaceX, has signed up 11 new...
