Space Systems + Nominal
Precision tools for validating spacecraft hardware, ensuring space system health, and managing constellation operations.
Nominal turns data produced in orbit into mission-grade decisions in real time.
Satellite programs produce a torrent of data: onboard bus telemetry, ephemeri, ground station forwarding, payload outputs, and more. Nominal brings it all onto a unified timeline, validating onboard storage at every contact window with ground testing as soon as the data reaches Earth.
Operators gain one integrated environment purpose-built for large operations across space and ground systems: synchronized timelines, 3D visualization, analog and digital signal processing, and continuous monitoring of assets through the life of constellation.
Where Tests Actually Get Stuck
Slow Feedback
Reviewing telemetry across multiple systems with disparate data sources delayed mission preparation.
Manual Infrastructure
Building highly reliable alerting and monitoring pipelines in-house consumed critical resources.
Knowledge Gaps
Teams struggled to adopt legacy workflows without training or dedicated support.
Fragmented Workflows
Data review in one place, alerting in another, no unified system of record.
Nominal connects orbital dynamics with system performance
The platform reconciles live ephemeris data with bus and payload telemetry to provide a single synchronized timeline for validation of asset health from single satellites to full constellations.
Visualize in 3D with precision
Render OEMs and TLEs with millisecond accuracy. Scrub through time bidirectionally, observing orbital tracks evolve with physics-based realism.
Overlay payload view cones, ground-station links, and communication footprints in 3D.
Validate satellite behavior automatically
Define subsystem health checks once, apply them across any layering of assets, from individual satellites, to clusters, to satellite-ground station pairs.
Surface anomalies, missed contacts, or mode transitions automatically, tied to time-synced mission data.
Manage constellations, not single assets
Track fleet-wide throughput, contact success rate, and subsystem reliability in one view.
Spot orbital drift, power degradation, or thermal anomalies across dozens of spacecraft.
Collaborate and report faster
Investigations move through Nominal with assignments, annotations, and version control. No scattered spreadsheets.
Generate contact logs, anomaly reports, and performance summaries with embedded data objects.
Synchronize runs instantly
All mission data including telemetry, video, and ground station diagnostics, lands in one catalog, ready for review.
Engineers scrub through synchronized playback instead of juggling multiple tools.
