L3Harris Technologies introduces new reflector antenna tailored for smallsat missions
by Staff Writers
Washington DC (SPX) Mar 17, 2020

The Smallsat Perimeter Truss Reflector (SPT) leverages L3Harris' innovative perimeter truss design yet optimizes its mass to meet tight stowage requirements for smallsat platforms. Offered in diameters up to 4 meters, the high-gain reflector enables low-cost launcher solutions and is compatible with reconfigurable beams and dynamic bandwidth allocation common on modern flexible satellite (flexsat). The SPT boasts surface accuracies and radio frequency (RF) reflectivity for the most challenging Ka-band applications. The reflector is well suited for broadband missions, synthetic aperture radar, radiometry, internet of things and mobile satellite service applications.

L3Harris Technologies has introduced a new small satellite reflector antenna that will help decrease the size, weight and overall time to produce smallsats.

Lighter and more compact than legacy designs, the new Smallsat Perimeter Truss (SPT) leverages L3Harris' advanced Perimeter Truss design, while optimizing its mass to make the unit lighter and smaller to package onto small satellites.

Offered in diameters up to four meters, and specifically designed for use on smallsat platforms, the Ka-band SPT is one-third the size and 50% the weight of previous designs. When stowed, the reflector is about the size of a commercial office fire extinguisher.

"Smallsats are playing a more important role in space and industry must continue to develop ways to make every satellite component smaller and lighter to keep pace with production and mission requirements," said Ed Zoiss, President, Space and Airborne Systems, L3Harris.

"We have done that with the new Smallsat Perimeter Truss - enabling L3Harris to package large high-gain antennas onto smaller satellite platforms."

Deep Space Antenna Upgrades to Affect Voyager Communications
Pasadena CA (JPL) Mar 05, 2020
Starting in early March, NASA's Voyager 2 will quietly coast through interstellar space without receiving commands from Earth. That's because the Voyager's primary means of communication, the Deep Space Network's 70-meter-wide (230-feet-wide) radio antenna in Canberra, Australia, will be undergoing critical upgrades for about 11 months. During this time, the Voyager team will still be able to receive science data from Voyager 2 on its mission to explore the outermost edge of the Sun's domain and beyond. ... read more
