World’s first electric propulsion satellite begins operations

Boeing recently announced that the first satellite using fully-electric propulsion is now in full operation. Dubbed the ABS-3A 702SP, the satellite, which launched last March, was handed to its owner, Bermuda-based telecommunication company, ABS, on August 31. Its goal is to provide communications services to the Americas, Europe, the Middle East, and Africa.

The ABS-3A relies on the Xenon Ion Propulsion System (XIPS), which employs a magnetic field to push ions around and generate thrust, making it the first satellite deployed with an all-electric drive.

According to Boeing, the technology is based on 210,000 hours of ion propulsion flight experience and is 10 times more efficient than liquid-fueled rockets. Four 25-cm thrusters using xenon as propellant allow the ABS-3A to maintain station-keeping while using just 5 kg of fuel per year. The satellite has an expected 15-year operational life span.

After launching last March aboard a Falcon 9 rocket, the XIPS drive allowed the satellite to power itself into geosynchronous orbit, where it is stationed at 3° West longitude. A second 702SP satellite called ABS-2A is scheduled to launch next year.

“With a successful launch, testing, and execution of orbit operations, we were able to deliver the first 702SP to ABS about one month earlier than planned,” said Mark Spiwak, president of Boeing Satellite Systems International. “The 702SP product line was designed to bring the latest technology into the hands of customers seeking adaptable and affordable solutions. In addition, the 702SP’s patented dual-launch capability helps customers share launch costs, which can significantly lower overall expenses for a satellite owner.”
