Ramp-Up in Antarctic Ice Loss Speeds Sea Level Rise

Ice losses from Antarctica have tripled since 2012, increasing global sea levels by 0.12 inch (3 millimeters) in that timeframe alone, according to a major new international climate assessment funded by NASA and ESA (European Space Agency).

Rockwell Collins’ Manpack radio passes critical MUOS testing

Rockwell Collins’ AN/PRC-162(V)1 software-defined military radio has passed a critical test to meet the security requirements required for operation with the Department of Defense’s (DoD) final version of the Mobile User Objective System (MUOS)

  • Marks progress in bringing MUOS communications capabilities to warfighters on the ground

CEDAR RAPIDS, Iowa (June 13, 2018) – Rockwell Collins’ AN/PRC-162(V)1 software-defined military radio is now the first tactical ground radio to pass a critical test to meet the security requirements required for operation with the Department of Defense’s (DoD) final version of the Mobile User Objective System (MUOS). The testing, known as Do No Harm (DNH), was performed on the AN/PRC-162 by the U.S. Navy Space and Naval Warfare Systems Command (SPAWAR) using the most current version of the MUOS waveform.

This achievement builds off the company’s recent milestone of developing the first airborne V/UHF radio to successfully pass the same test.

“MUOS will provide the warfighter with more mobility, improved signal quality and availability, which is especially important for units on the ground if they’re operating in rough terrain or communicating beyond line of sight,” said Troy Brunk, vice president and general manager, Communication, Navigation and Electronic Warfare Solutions for Rockwell Collins. “We understand how critical MUOS is to the future success of our armed forces and we’ll continue to lead the development of this technology both for use in the air and on the ground.”

A next-generation advancement over today’s UHF SATCOM communications, MUOS will provide military forces with worldwide, crystal-clear voice, video and mission data over a secure high-speed Internet Protocol-based system. MUOS will also provide a connection into the Global Information Grid, as well as into the Defense Switched Network, and has been successfully tested to distribute Integrated Broadcast Service (IBS) messages. MUOS also has been demonstrated in the Arctic up to 89.5 degrees North latitude, an event in which Rockwell Collins participated.
