Key Terms

6 terms

edge computing technical

"Fortis system, which is enhanced with edge computing technology and ruggedized"

Edge computing is a technology that processes data close to where it is generated, such as sensors or devices, rather than sending it all to a distant central location. This allows for faster decision-making and reduces delays, much like having a local office handle urgent matters instead of waiting for instructions from a main headquarters. For investors, it signifies improved efficiency and real-time insights, which can enhance the performance of technology-dependent industries.

fpga technical

"pairs a quad-core ARM processor and reconfigurable FPGA with an integrated NVIDIA"

A field-programmable gate array (FPGA) is a type of computer chip whose internal wiring can be changed after it is made, allowing engineers to program custom hardware functions without designing a new chip. For investors, FPGAs matter because that flexibility lets companies quickly adapt products to new software, standards, or customer needs—like a toolbox that can be rearranged to build different machines—so demand and pricing can shift with trends in data centers, telecommunications, AI, and specialized electronics.

ai/ml technical

"integrated NVIDIA edge AI/ML engine and assured positioning, navigation, and timing"

AI/ML stands for artificial intelligence and machine learning, software systems that identify patterns in data and make predictions or automate decisions, improving performance as they process more information. Investors care because these technologies can boost revenue, cut costs and create competitive advantages — like a factory that learns to produce goods faster and with fewer mistakes — while also introducing execution, ethical and regulatory risks that can affect a company’s value.

technology readiness level 9 technical

"expected to advance Fortis Maxima to Technology Readiness Level 9 (TRL-9)"

Technology Readiness Level 9 (TRL 9) indicates a product or system has completed development and been proven fully functional in its intended, real-world operating environment. For investors, TRL 9 signals minimal technical risk from further development — like a car that has passed all road tests and is ready for showroom sales — which makes commercialization and revenue generation more predictable but does not remove market, regulatory, or execution risks.

command and data handling technical

"Fortis Maxima proprietary Command and Data Handling (C&DH) system"

The onboard system that receives, interprets and executes control commands and collects, formats and stores mission data for a spacecraft, satellite or remote instrument. Think of it as the device’s brain and filing cabinet combined: it routes instructions from the ground, runs software that keeps hardware working, and packages sensor or status data for transmission back to operators; its reliability directly affects operational uptime, delivery of revenue-generating services and maintenance costs, so investors watch it as a key technical and risk factor.

assured positioning, navigation, and timing technical

"engine and assured positioning, navigation, and timing (A-PNT) suite"

Assured positioning, navigation, and timing means reliable, tamper-resistant services that tell devices where they are, how to move, and what time it is—like a combined, unbreakable map and clock for machines. Investors care because many industries (transportation, telecom, finance, defense) depend on this accuracy and resilience; companies that provide or protect these services can gain steady demand, while failures can cause costly disruptions and regulatory or liability risks.

CAPE CANAVERAL, Fla., June 16, 2026 /PRNewswire/ -- Sidus Space, Inc. (NASDAQ: SIDU) ("Sidus" or the "Company"), an innovative space and defense technology company, today announced that its next LizzieSat® has successfully completed vibration testing, a key environmental qualification milestone for SpaceX's Transporter-18 rideshare mission from Vandenberg Space Force Base in California, currently scheduled for launch no earlier than October 2026.

Vibration testing simulates the intense mechanical loads a spacecraft experiences during launch and ascent. The testing was conducted at Element U.S. Space & Defense's facility in Orlando, Florida, an accredited independent provider of product qualification and environmental testing services. Completing this testing is designed to confirm that the satellite's structure, components, and integrated payloads can withstand the stresses of liftoff and remain fully operational on orbit, a critical step in clearing the spacecraft for final integration and shipment to the launch site.

"Successfully completing vibration testing keeps us on schedule for our targeted launch on SpaceX's upcoming Transporter-18 mission. This also reflects the maturity of the LizzieSat platform and the strength of our in-house engineering and manufacturing capabilities," said Carol Craig, Founder, Chief Executive Officer and Chairwoman of Sidus Space. "Each LizzieSat mission builds on the flight heritage of the last, and this is the first to carry our own Fortis™ Maxima proprietary Command and Data Handling (C&DH) system, an important step toward demonstrating our own technology on-orbit for our defense and commercial customers."

This mission marks the Company's first flight for the Fortis system, which is enhanced with edge computing technology and ruggedized for operations across space, air, land, and sea. Operating aboard LizzieSat in the demanding environment of space is expected to advance Fortis Maxima to Technology Readiness Level 9 (TRL-9), the highest level of technology maturity, denoting a system proven through successful mission operations. Fortis Maxima pairs a quad-core ARM processor and reconfigurable FPGA with an integrated NVIDIA edge AI/ML engine and assured positioning, navigation, and timing (A-PNT) suite, delivering near real-time, AI-driven processing at the edge for dual-use defense and commercial applications. By maturing this technology in orbit, Sidus aims to position Fortis Maxima for broader adoption across its defense and commercial customer base.

Following vibration testing, the satellite will proceed to final integration and testing before delivery to the launch provider. Sidus designs, manufactures, assembles, and tests its LizzieSat spacecraft in-house at its facility in Cape Canaveral, Florida, reflecting the vertically integrated model that underpins its rapid, cost-effective approach to mission delivery.
