CesiumAstro develops end-to-end space and airborne communications systems, including active phased array antennas, software-defined radios, and complete payloads. Its technology enables electronically steered beams for inter-satellite links, high-rate downlinks, lunar and deep-space communication, and 5G/NTN networks. It ships plug‑and‑play, commercially manufactured hardware and SDR software as a full-stack solution, reducing development time and cost. The company targets both government programs (NASA, DoD) and commercial space ventures, aiming to make space-based connectivity more accessible and adaptable.

The Export-Import Bank of the United States has signed a $300 million credit agreement with CesiumAstro, an Austin-based space and defence connectivity specialist. The agreement, announced on 9 September, aims to consolidate the company's design, manufacturing, assembly and test operations into a single 270,000-square-foot US facility currently under construction. The financing includes a $20 million revolving credit facility from JP Morgan, making it EXIM's largest loan approval under its "Make More in America" initiative. CesiumAstro is the only company to receive a second credit agreement under the programme. EXIM previously approved $185 million in financing to CesiumAstro in January 2026, later increased to $280 million. Founded in 2017, CesiumAstro recently secured a $470 million Series C funding round.
CesiumAstro buys 1Aardvark to add mission software for defense space. * 1Aardvark is a service-disabled veteran-owned and HUBZone-certified business in Manassas, Virginia * Its work covers missile defense and missile tracking programs * The deal follows CesiumAstro's purchases of Vidrovr and Jariet Technologies this year CesiumAstro has acquired 1Aardvark, adding mission software and systems engineering to a portfolio built around satellites and communications payloads. CesiumAstro announced the deal Tuesday. 1Aardvark, based in Manassas, Virginia, builds software, algorithms and systems engineering for national defense programs. It holds service-disabled veteran-owned small business and HUBZone certifications. What does 1Aardvark bring to CesiumAstro? 1Aardvark's software supports missile defense and missile tracking work. The company builds systems that enable distributed platforms to coordinate and execute missions in contested or disconnected environments. CesiumAstro expects the pairing to yield spacecraft that adjust to changing conditions and keep operating when connectivity degrades. Shey Sabripour, founder and CEO of CesiumAstro, said defense space systems increasingly require software that can adapt and make decisions. According to Ryan Kenward, president of 1Aardvark, joining CesiumAstro extends the company's work pushing mission capability to the edge. How does the deal fit CesiumAstro's acquisition strategy? The 1Aardvark deal lands days after CesiumAstro closed its purchase of Jariet Technologies, a semiconductor firm focused on millimeter-wave radio frequency system-on-chip designs. That deal gave the company in-house chip capability to pair with its phased-array antenna and payload work. The company also acquired Vidrovr in March, an AI firm specializing in real-time multimodal signal analysis. Vidrovr co-founder Joe Ellis oversees integration of machine learning tools into the CesiumAstro portfolio. CesiumAstro closed a $470 million Series C round in February and took $200 million in Export-Import Bank financing in January to acquire a 270,000-square-foot West Austin facility.
