SPACE
We support space mission systems —strengthening secure mission and enterprise environments, mission networks, and data flows that operators rely on every day. By applying rigorous analysis, modeling, and data expertise, our teams help translate high-volume mission data into insight that improves readiness, resilience, and mission execution across dynamic space operations.
Solution in Action
We address challenges like implementing Zero Trust in disconnected environments and enhance network protection without relying on external cloud services. Ultimately, we empower military operations with secure and interoperable technologies.
More SolutionsChallenge
The satellite sensor calibration and validation (Cal/Val) activities conducted by the NOAA NESDIS, STAR, are foundational to NOAA’s mission and directly support the protection of life, property, and the economy of the United States. These activities ensure the accuracy and reliability of satellite data products used for weather forecasting, environmental monitoring, disaster response, and long-term assessments. Continuing these operations is vital for protecting lives, infrastructure, and national interests.
Solution
Entarian’s Cal/Val services ensure that satellite radiometers, sounders, and imagers provide precise measurements of Earth’s atmosphere, oceans, and land surface. These measurements feed into numerical weather prediction models used by the National Weather Service. We ensure satellite observations are trustworthy for rapid detection and monitoring of wildfires, volcanic eruptions, floods, droughts, hurricanes, and oil spills.
Impact
By improving the accuracy and usability of weather forecasts, we enable earlier detection of hazards and more informed decision‑making during severe weather events. Timely, actionable insights support faster and more effective disaster response while helping critical sectors—including aviation, agriculture, and energy—anticipate and mitigate weather‑related risks. Together, these outcomes strengthen emergency preparedness and response efforts and contribute to national security by protecting lives, infrastructure, and economic stability.
What we do
Antenna operations, maintenance, and sustainment engineering
We provide comprehensive antenna operations, maintenance, and sustainment engineering for satellite ground systems, ensuring high availability, precision tracking, and reliable RF performance across all mission phases. Our capabilities include preventative and corrective maintenance, calibration, anomaly resolution, and lifecycle engineering to sustain and modernize antenna assets. Leveraging data-driven monitoring and disciplined configuration control, we optimize performance, minimize downtime, and ensure continuous mission support in demanding operational environments.
Data processing, archive, and dissemination
Entarian supports the full data lifecycle from the moment the data is received on the ground, through ground system formatting and processing, further processing to Level 1B, Level 2+, Level 3 and higher data formats. This data is then used to feed environmental, weather and earth observing models to ensure that data products, environmental monitoring and other weather related decisions are informed and prioritized. This data is stored in long-term archives that store the data in optimized ways to facilitate efficient, low-cost storage and quick, expedient retrieval.
Ground segment and network operations management
We manage a range of satellite ground systems supporting Low Earth Orbit (LEO), Geosynchronous and Lagrange orbits to ensure that all mission functions maximize availability and performance to ensure data receipt, data processing, health and status telemetry, instrument data, flight parameters and satellite commanding are functioning normally promote continuous, consistent data streams that allow for smooth satellite operation, as well as data product generation and distribution upstream to all end users worldwide.
Real-time anomaly detection and resolution
We use a disciplined, experienced approach to identifying, detecting, characterizing, characterizing and resolving real-time operational anomalies and events. Anomalies are triaged and diagnosed by subject matter experts, who can identify and diagnose anomalies and implement corrective actions or workarounds that restore operations while minimizing downtime or loss of data, while implementing resolutions once the system is back up and operational. Our team uses documented procedures combined with extensive training and expertise to diagnose these anomalies quickly.
Mission readiness and systems integration testing
We deliver comprehensive mission readiness and systems integration testing through a disciplined systems engineering process that verifies end-to-end performance across space, ground, network, and data segments. Our approach includes rigorous interface validation, integrated test events, and high-fidelity mission rehearsals to ensure all components operate seamlessly under nominal and contingency conditions. This capability ensures fully validated, interoperable systems and high-confidence mission readiness prior to operational deployment.
Operational procedure development and training
We develop comprehensive operational procedures and SOPs tailored to satellite mission operations, ensuring standardized, repeatable execution across all ground system functions. Our training approach includes structured certification programs, scenario-based simulations, and proficiency evaluations to build and sustain operator expertise. This capability ensures a highly trained, mission-ready workforce capable of executing both nominal operations and contingency responses with precision and consistency.
Satellite ground system engineering
We provide end-to-end satellite ground system engineering encompassing design, integration, modernization, and sustainment of mission-critical infrastructure. Our capabilities span command and control systems, communications networks, data processing, and cybersecurity, all governed by a disciplined systems engineering and configuration management framework. This approach ensures scalable, resilient, and high-performance ground systems that reliably support continuous mission operations. Our thorough process ensures that all requirements are carried through the design and implementation phases, are fully implemented and perform to exact specifications, and are validated through our detailed test and integration phases.
Modeling and simulation
We deliver advanced modeling and simulation capabilities to support the design, integration, and optimization of satellite ground systems and mission operations. Our approach leverages high-fidelity models, digital twins, satellite ground simulators used to run operational tests and checks, and scenario-based simulations to evaluate system performance, validate concepts, and reduce operational risk. This capability enables data-driven decision making, enhances mission readiness, and supports continuous improvement across the system lifecycle.
Cloud development, migration, operations, and security
We deliver end-to-end cloud capabilities for satellite ground systems, including SAFe Agile development, DevSecOps approaches, seamless migration of legacy and mission-critical workloads, and resilient day-to-day operations. Our approach leverages cloud-native architectures, automation, and containerization to improve scalability, performance, and cost efficiency while maintaining strict mission availability requirements. We implement robust cybersecurity practices aligned with federal standards, including zero trust principles, continuous monitoring, and automated compliance enforcement. This integrated capability enables secure, agile, and highly available ground system operations across hybrid and multi-cloud environments.
