L-3 Cincinnati Electronics Participates in United Launch Alliance’s Atlas V Rocket Launch of NASA's MMS Mission

April 14, 2015

CINCINNATI – L-3 Cincinnati Electronics (L-3 CE) announced today that it has participated in the United Launch Alliance (ULA) Atlas V rocket launch of NASA’s Magnetospheric Multiscale (MMS) mission. Liftoff occurred at 10:44 p.m. Eastern Time on Thursday, March 12, 2015 from Space Launch Complex-41 at Cape Canaveral Air Force Station, Fla., marking the 94th successful launch for ULA. Since ULA’s formation in 2006, L-3 CE has provided significant avionics content on every ULA Atlas launch.

L-3 CE supported the MMS mission by providing both navigation and communication products for the satellite constellation, including its S-Band coherent transponder. On the launch vehicle itself, L-3 CE provided Atlas V avionics, which helped insert the MMS into orbit. The avionics suite provided launch vehicle control and power distribution and included L-3’s Data Acquisition and Video Integrated System (DAVIS), which collected telemetry data and HD video. The launch vehicle’s Tracking and Data Relay Satellite System (TDRSS) transmitter and the range safety receivers were also part of L-3 CE’s extensive support of this mission.

“It’s thrilling to support both the launch vehicle and the satellite on the same mission,” said Mark Dapore, vice president and general manager of Space Electronics for L-3 CE. “We have been a proven ULA partner for each of the last 94 Atlas and Delta launches, and we are honored to contribute to this milestone space exploration mission.”

The MMS spacecraft constellation will study phenomena related to the Earth’s magnetosphere. This information will allow predictive knowledge of the process that governs space weather and affects technology such as communication networks, GPS navigation and electrical power grids. MMS consists of four identical spacecraft that will work together to provide the first three-dimensional view of these phenomena.

L-3 CE’s expertise in high-reliability telemetry, tracking and command (TT&C) and wideband data transmission to Earth ground stations has made it a leader in high-technology space electronics. To learn more about L-3 CE, please visit the company’s website at www.L3T.com/ce.
