MCLEAN, Va., May 6, 2025 /PRNewswire/ -- Iridium Communications Inc. (Nasdaq: IRDM), a leading provider of global voice and data satellite communications, today announced a special U.S. government version of the Iridium® 9603 module built for Enhanced Short Burst Data (ESBD). ESBD is a low-latency and secure messaging service designed to provide optimal transmission security (TRANSEC) for the U.S. government and approved allies.
The ESBD version can act as a drop-in replacement for the existing Iridium 9603 Short Burst Data® (SBD®) module. Alongside Iridium's known reliability and resiliency, Iridium 9603 ESBD can deliver secure one- or two-way messaging with an increased payload capacity for mobile-originated (MO) and mobile-terminated (MT) messages. Example applications range from command and control (C2) and image data transfer to personnel and asset tracking.
"Iridium 9603 ESBD is a testament to Iridium's commitment to investing in secure, low-latency solutions that address threats in the changing global environment," said Scott Scheimreif, executive vice president, government programs, Iridium. "The new module offers end-to-end communication security for critical operations, helping ensure warfighters can exchange vital information with confidence — no matter the environment. This capability not only safeguards mission success but also reflects the Department of Defense's trust in Iridium's proven technology, network reliability, and operational excellence."
The upgraded module represents the latest innovation of Iridium to support the Enhanced Mobile Satellite Services (EMSS) program, a decades-long partnership that delivers truly global standard and secure voice, broadcast, PTT, and other services to an unlimited number of Department of Defense and DoD-approved subscribers anywhere on Earth. Iridium 9603 ESBD is targeted to be made available to EMSS-approved value-added manufacturers in July.
With its unique low-Earth orbit (LEO) satellite network, Iridium provides resilient L-band connectivity and unparalleled global coverage that does not encounter permanent line-of-sight blockages faced by geostationary (GEO) systems. This helps to ensure the delivery of mission-critical communications for the DoD and other federal agencies. Whether in high-risk combat zones or during inclement weather events, the Iridium network provides pole-to-pole satellite communications that keep users connected when it's needed most, making it critically important for the Joint All Domain Command and Control's (JADC2) Primary, Alternate, Contingency, and Emergency (PACE) communications architecture.

Iridium Equips 9603 Module with Enhanced Short Burst Data Capabilities for Government Users

YANTAI, China, Dec. 8, 2025 /PRNewswire/ -- On December 4, the 2025 Shandong Green Low-carbon High-quality Development Conference was held in Yantai, Shandong province. Against the backdrop of the fifth anniversary of China's 'dual carbon' goals, Yantai's achievements—as one of the country's first pilot cities for carbon peaking and for realizing the value of ecological products—are more than local practice; they represent a notable example in the global conversation about sustainable development pathways for bay areas.
From the precision manufacturing of Tokyo Bay to the financial innovation of New York Bay and the deep integration of the Guangdong–Hong Kong–Macao Greater Bay Area, bay areas have become pivotal geographic units driving global economic and technological changes. On the shores of the Yellow Sea and the Bohai Sea, Yantai—a representative bay–area economy—is addressing contemporary challenges through its green development practices.
As a cradle of China's modern industry, Yantai's industrial system spans 37 of the country's 41 major industrial categories. It is the first ordinary prefecture–level city in the northern part of China to join the 'one–trillion–yuan GDP club,' and is hailed as the region's strongest prefecture–level city. Yantai is currently home to more than 50 listed companies with a combined market value exceeding 1.2 trillion yuan.
In recent years, Yantai has prioritized clean energy as one of its 16 key industrial chains, building a new energy system that coordinates nuclear, wind, solar, and hydrogen power alongside energy storage and liquefied natural gas (LNG). It has advanced major projects in nuclear power, offshore wind power, and offshore photovoltaics, forging a distinct clean-energy identity.
The development of clean energy in Yantai boasts eight notable 'firsts': producing Shandong's first kilowatt-hour of nuclear power and first kilowatt-hour of offshore wind power; delivering China's first kilowatt-hour from a pile–based fixed offshore photovoltaic project and the world's first from a deep–sea floating offshore photovoltaic project; completing the country's first integrated demonstration of offshore wind power and marine ranching; constructing the country's largest coastal photovoltaic-plus-energy-storage station; bringing the country's first commercial nuclear energy heating demonstration project into operation; and achieving the highest installed clean-energy capacity in Shandong. These accomplishments represent a systemic revolution in energy use, not merely a collection of projects.
Data show that, over the past three years, Yantai has cut its energy consumption intensity by a cumulative 20.9%, meeting its energy saving and carbon reduction targets for 19 consecutive years. Its installed clean-energy capacity has now surpassed 17 million kilowatts.
Looking ahead, Yantai is charting a new growth path with six future-oriented industries—life sciences, deep-sea and aerospace technologies, next–generation nuclear power, artificial intelligence, new electronic materials, and humanoid robotics—which are expected to drive green, low–carbon, high–quality development. The city projects that total output value of industrial enterprises above the designated size will exceed 1.7 trillion yuan by 2027, a target supported by sustained investment in innovation.
