Considering that then, the coolly-monikered TBIRD has transmitted terabytes of data to a ground-based receiver in California at the crazy rate of up to 100 gigabits per second. Now, NASA has actually verified that TBIRD downlinked 1.4 terabytes over laser interactions on a Dec. 1 pass that lasted around five minutes.
The present 100 Gbps information rate is more than 1,000 times greater than the radio-frequency links generally utilized for satellite interaction and the greatest ever achieved by a laser link from area to ground. These world-record speeds were enabled by a communications payload about the size of a tissue box.
The acceleration will benefit lots of science missions, from Earth observation to area exploration, as instrument capabilities enhance to record more high-resolution data, experiments become remote-controlled, and spacecraft travel further into deep area.

” With the broadening interest and development in space-based laser interactions, Lincoln Laboratory continues to press the envelope of what is possible,” Wang said. “TBIRD heralds a new method with the possible to further increase data rate capabilities; diminish weight, power, and size; and lower lasercom mission expenses.”.
The TBIRD communications payload was produced and built at Lincoln Laboratory and connected to a Terran Orbital CubeSat as part of NASAs Pathfinder Technology Demonstrator effort. NASA Ames Research Center started this program to produce a CubeSat bus, or “lorry,” that would make it much easier and less costly to release science and innovation demonstration satellites into orbit.
Considering that most of the weather in Table Mountain, California, occurs below the mountains top, this area of the sky is usually clear for laser communication. With the help of the NASA Jet Propulsion Laboratorys Optical Communications Telescope Laboratorys one-meter telescope and adaptive optics to correct distortions triggered by atmospheric turbulence, this ground station utilizes TBIRD-specific ground interaction hardware from Lincoln Laboratory.
” Weve demonstrated a greater data rate than ever before in a smaller package than ever in the past,” says Jade Wang, the labs program supervisor for the TBIRD payload and ground interactions and assistant leader of the Optical and Quantum Communications Technology Group. “While sending out information from area using lasers might sound futuristic, the exact same technical concept lags the fiber-optic internet we utilize every day. The distinction is that the laser transmissions are happening outdoors atmosphere, instead of in included fibers.”.
” Weve shown a higher information rate than ever before in a smaller bundle than ever in the past,” states Jade Wang, the labs program supervisor for the TBIRD payload and ground communications and assistant leader of the Optical and Quantum Communications Technology Group. Infrared light, used in laser interactions, has a much greater frequency (or shorter wavelength) than radio waves, allowing for higher data compression. Similar to the transition from dial-up to high-speed web here on Earth, laser interactions will enable scientists to send 100 to 1,000 times more data than current radio-frequency systems.
If youve ever taken part in a video conference, played an online game or watched a movie in high def, youre using high-data-rate links that travel along glass or plastic fiber optics. These fibers, which have to do with the very same size as human hair, are bundled together to form cables that utilize fast-moving pulses of light from a laser or other source to transfer data. In todays Internet age, where massive amounts of data should be quickly and dependably dispersed across the world, fiber-optic interactions are important.
MIT Lincoln Laboratory envisioned the TBIRD objective in 2014 as a way to offer science objectives unheard-of capability at a reasonably reasonable rate. Science instruments in area create more data than can be transferred by basic interactions channels from area to the ground. TBIRD can assist scientists from throughout the world totally use laser communications to downlink all the data they might ever want with the aid of compact, budget friendly space and ground terminals.
