Key Terms

space domain awareness technical

The practice of detecting, tracking and predicting the location and behavior of objects in Earth orbit—such as active satellites, debris and spent rocket stages—so operators can avoid collisions and manage risks. For investors it matters because better awareness protects valuable satellite services, supports defense and commercial contracts, reduces insurance losses and creates market opportunities for companies that provide sensors, data and collision-avoidance services; think of it as air-traffic control for space.

4d radar technical

4D radar is a sensing system that maps objects in three-dimensional space and tracks their movement over time, so it tells you where something is and how fast it’s moving. For investors, it signals a more advanced form of radar used in areas like autonomous vehicles, drones, industrial safety and security — potentially improving accuracy, reliability and regulatory compliance, which can affect product competitiveness and market value.

electronically scanned array radar technical

An electronically scanned array radar is a sophisticated system that uses many small antennas to quickly and precisely detect objects or movements in the sky or on the ground. Unlike traditional radars that move parts to scan an area, this technology can instantly shift its focus electronically, providing faster and more accurate tracking. For investors, this means improved security, navigation, and weather prediction, all of which can impact various industries and economic stability.

guidance, navigation, and control (gnc) technical

Guidance, navigation, and control (GNC) refers to the systems that direct and manage the movement of a vehicle or device, ensuring it reaches its intended destination safely and accurately. Think of it as the GPS and steering system of a rocket or drone, constantly adjusting its path. For investors, strong GNC capabilities can indicate a company's expertise in precise operations or technology, which may impact its performance and growth prospects.

technical and business assistance (taba) financial

Technical and business assistance (TABA) involves providing expert advice, training, and support to help organizations improve their operations, products, or services. It’s like offering guidance and tools to help a business run more efficiently and effectively. For investors, TABA can signal efforts to strengthen a company’s capabilities and long-term growth prospects.

constellation technical

A constellation is a group of interconnected companies or assets that move together because they are affected by similar factors or industry trends. For investors, understanding these groupings helps identify patterns, manage risks, and spot opportunities by seeing how different parts of the market are linked and influenced by common forces.

orbital debris technical

Material left in orbit around Earth from spent rocket stages, broken satellites, paint flakes and fragments from collisions — often called space debris. Like a crowded highway of fast-moving shards, it can strike and disable active satellites, raising repair and replacement costs, driving higher insurance premiums, complicating launches and triggering regulation; investors watch it because it can materially affect the value and risk of space-related businesses and services.

Sidus Space to Provide Spacecraft Integration Expertise and Constellation Scaling Analysis for Space Domain Awareness

CAPE CANAVERAL, Fla.--(BUSINESS WIRE)-- Sidus Space, Inc. (NASDAQ: SIDU), an innovative space and defense technology company, today announced its role as a subcontractor supporting MobLobSpace, Inc. under a NASA Small Business Innovation Research (SBIR) award. The six-month design study will focus on designing and planning a mission to host an advanced space-based 4D radar system onboard Sidus’ LizzieSat satellite platform, delivering critical Space Domain Awareness (SDA) data services to track centimeter-scale orbital debris.

Under the $173,000 NASA SBIR award, MobLobSpace will develop an adaptive electronically scanned array radar as part of NASA’s Space Sustainability Strategy programs. Sidus Space will provide input on host spacecraft specifications, including power and Guidance, Navigation, and Control (GNC) systems, to ensure seamless integration of the radar payload aboard LizzieSat.

“Partnering with MobLobSpace to host advanced radar technology aboard LizzieSat represents a significant step toward improving space situational awareness and mitigating collision risks,” said Carol Craig, CEO of Sidus Space. “This collaboration positions Sidus to deliver scalable, commercially viable solutions that support the long-term sustainability of space operations.”

In addition to the design study, Sidus has received an add-on Technical and Business Assistance (TABA) award to conduct a study exploring scale pathways for the SDA data service. This analysis will examine the number of satellite nodes required for a constellation capable of complete orbital coverage and assess deployment strategies to meet growing demand for orbital debris tracking.

“Hosting an adaptive radar in orbit demands precise power and GNC integration,” said Charlton Shackleton, Co-Founder of MobLobSpace. “LizzieSat’s design provides the flexibility needed to support this capability.”

This collaboration underscores Sidus Space’s commitment to advancing space sustainability through innovative partnerships and technology integration. By leveraging LizzieSat’s versatility and MobLobSpace’s radar expertise, the project aims to deliver critical data services that protect assets and ensure safe operations in an increasingly congested orbital environment.
