The radio frequency band that many NASA missions use to communicate with spacecraft — S-band — is getting a bit crowded and noisy, and likely to get more [congested] as science missions demand higher and higher data rates.
A team of NASA technologists at NASA's Goddard Space Flight Center in Greenbelt, Maryland, just may have a solution, particularly for potential missions that plan to operate in low-Earth orbit and have limited real estate to accommodate communications gear.
Under two different research and development projects, technologists Mae Huang and Victor Marrero-Fontanez have collaborated to test and verify components of a prototype end-to-end Ka-band space communications system, which promises significantly higher data rates — a whopping 2.4 gigabits of data per second (Gbps) — over more traditional S-band systems, which theoretically could achieve data rates of 90 megabits of data per second (Mbps).
