The Most Sensitive Optical Receivers Yet for for Laser-Beam Based Space Communications

Posted by in categories: internet, space

Communications in space demand the most sensitive receivers possible for maximum reach, while also requiring high bit-rate operations. A novel concept for laser-beam based communications, using an almost noiseless optical preamplifier in the receiver, was recently demonstrated by researchers at Chalmers University of Technology, Sweden.

In a new paper published in the scientific journal Nature: Light Science & Applications, a team of researchers describes a free-space optical transmission system relying on an optical amplifier that, in principle, does not add any excess noise — in contrast to all other preexisting optical amplifiers, referred to as phase-sensitive amplifiers (PSAs).

The researchers’ new concept demonstrates an unprecedented receiver sensitivity of just one photon-per-information bit at a data rate of 10 gigabits per second.

Elon Musk Is Providing Internet To Wildfire Towns To Help Firefighters

Posted by in categories: Elon Musk, internet, satellites

Elon Musk’s company SpaceX has given emergency responders in Washington access to its Starlink satellites to help fight fires.

Through the satellite-based internet constellation Starlink, SpaceX plans to provide broadband internet across the globe and enable connectivity to billions of people who may not have reliable internet access.

SpaceX has already launched hundreds of satellites into orbit, though the firefighters’ use of the network is the first early application of the internet service to be disclosed.

The private space firm hopes to eventually launch tens of thousands of Starlink satellites to create a constellation capable of beaming high-speed broadband down to 99 per cent of the inhabited world.

“Once these satellites reach their target position, we will be able to roll out a fairly wide public beta in northern US and hopefully southern Canada,” Musk tweeted following the launch.

“Other countries to follow as soon as we receive regulatory approval.”

The Pentagon Commissioned SpaceX to Build Missile-Tracking Satellites

Posted by in categories: internet, military, satellites

#SpaceX just partnered with the U.S. military’s #Space Development Agency (SDA) to manufacture four new satellites that the Pentagon will use to detect and track missiles from space.

The $149 million contract is for four satellites, according to Reuters, which are scheduled to be delivered by the end of 2022. The actual #missile-tracking sensors will be developed by a separate subcontractor and attached to the #satellites later, but the military is hoping to piggyback on SpaceX’s recent success in ramping up satellite production for its #Starlink network.

It’s the first time SpaceX is building satellites for the military.

SpaceX, L3Harris win Space Development Agency contracts to build missile-warning satellites

Posted by in categories: internet, military, satellites

SpaceX is developing a new satellite bus for the Space Development Agency based on the Starlink design.

WASHINGTON — The Space Development Agency awarded SpaceX a $149 million contract and L3Harris a $193.5 million contract to each build four satellites to detect and track ballistic and hypersonic missiles.

The contracts announced Oct. 5 are for the first eight satellites of a potentially much larger Space Development Agency constellation of sensor satellites known as Tracking Layer Tranche 0. This is SpaceX’s first military contract to produce satellites.
