NASA Eyes GPS at the Moon for Artemis Missions

  • Magazine Article
  • TBMG-35111
Published 2019-09-01 by Tech Briefs Media Group in United States

The Global Positioning System (GPS), a satellite-based navigation system used by an estimated four billion people worldwide to figure out where they are on Earth at any moment, could be used to pilot in and around lunar orbit during future Artemis missions to the Moon.

Multi- and Wide-Band Single-Feed Patch Antenna

  • Magazine Article
  • TBMG-35130
Published 2019-09-01 by Tech Briefs Media Group in United States

A novel patch antenna technology was developed that provides significant benefits to NASA satellite communication applications, offering a unique wide-band/multi-band operating capability. For other non-space applications, the antenna design also offers broadband capability with high gain for applications where signal strength and smaller antenna sizes are important. The technology was developed to design antennas for satellites where the target communication frequency is unknown or unassigned.

A New Approach to Satellite Communications

Published 2018-09-01 by SAE International in United States

Satellites launched with the purpose of relaying communications have been enabling around-the-globe transmissions of information for half a century. And in this current era of hybrid warfare, that means this decades-old hardware needs to be able to manage the command and control of unmanned aircraft.

  • TBMG-32728
Published 2018-08-01 by Tech Briefs Media Group in United States

As satellites and astronauts travel further out in space, the more communication challenges they face. NASA launched the InSight Mission on May 5, 2018 from Vandenberg Air Force Base, California. InSight was designed to collect data on Mars quakes and the processes that shaped the rocky planet to help us better understand how it formed. Getting the information back to the scientists here on Earth required a variety of antennas on the spacecraft.

Published 2018-04-01 by Tech Briefs Media Group in United States

NASA Glenn’s cup cylindrical waveguide antenna (CCWA) is a short backfire microwave antenna capable of simultaneously supporting the transmission or reception of two distinct signals having opposite circular polarizations. Short backfire antennas are widely used in mobile satellite communications, tracking, telemetry, and wireless local area networks because of their compactness and excellent radiation characteristics.

Secure Optical Quantum Communications

NASA’s Glenn Research Center has developed a method of using entangled-photon pairs to produce highly secure mobile communications that require mere milliwatts of power. Conventional gas Argon-ion laser sources are too large, expensive, and power-intensive to use in portable applications. By contrast, Glenn’s patented optical quantum communication method produces entangled-photon pairs approximately a million times more efficiently than conventional sources, in a system that is small and light enough to be portable. Furthermore, because this method transmits digital information by detecting small temporal shifts between entangled photons, its superior signal-to-noise ratio facilitates highly secure communications in very noisy free space and fiber-optic environments. Originally developed for micro-robots used for deep space exploration, this technology represents a breakthrough for a wide variety of terrestrial, scientific, military, and other field-deployable applications including fiberoptic and satellite communications.
