Antennas Deployed
L3Harris announced the successfully deployment Nov. 20 of Jupiter-3’s four large reflector antennas.
“The L3Harris-built reflectors onboard the Jupiter-3 communications satellite are based on materials and configurations deployed on similar communication satellites — utilizing flight proven materials and subassemblies,” Colin Mitchell, L3Harris RF Systems vice president and general manager, told SpaceNews by email. “The reflectors onboard Jupiter-3 offer proven design and assembly processes as other large reflectors that have been manufactured in our Florida facility.”
Still, it remains challenging to design and configure antennas for ultra-high-capacity communications satellites that fit inside standard launch fairings. To accomplish the objective, L3Harris relies on advanced technology and sophisticated packaging techniques, Mitchell said.
Ground System Testing
With the antennas deployed, Echostar’s Hughes Network Systems is testing Jupiter-3’s ability to communicate with ground systems. Once testing is completed, Jupiter-3 is expected to provide more than 500 gigabits per second of broadband capacity for Hughesnet customers including airlines, corporations, governments and consumers in North and South America.
Hughes expects Jupiter-3 to enter service by the end of the year.
“As the largest commercial satellite ever built, Jupiter-3 will double the capacity of our fleet, serving more customers who live beyond the reach of cable and fiber internet by providing ubiquitous connectivity throughout the Americas,” Echostar CEO Hamid Akhavan said in a statement.
