Global Sensor Network (GSN)

The GSN Metrics provides visibility into space domain awareness by aggregating observational data from Slingshot Global Sensor Network (SGSN).

Updated today

Overview

This dashboard provides visibility into:

  • Satellite tracking coverage

  • Observational activity

  • Catalog completeness

  • Tracking performance metrics

  • Data latency and accuracy

The GSN dashboard helps operators, analysts, and mission planners understand how effectively objects in orbit are being monitored.


Accessing the GSN Dashboard

You can access the Global Sensor Network dashboard from the App Switcher.

Steps

  1. Click the App Switcher (grid icon) in the top-left corner of the portal.

  2. Select GSN Metrics.

You may also access GSN from Quick Actions

The dashboard will load with the latest sensor network statistics and performance metrics.


Slingshot Orbital Alert Highlights

At the top of the dashboard is the Slingshot Orbital Alert Highlights section.

This panel displays notable events and insights detected across the sensor network, such as:

  • Satellite maneuvers

  • Orbital changes

  • Object fragmentation events

  • Conjunction activities

  • Mission anomalies

Each alert includes a Read Story link for deeper context and analysis.


Lifetime Metrics

The Lifetime Metrics section summarizes the overall performance and scale of the sensor network.

These metrics include:

Observations Made

Total number of sensor observations collected across the network.

This metric reflects the historical scale of tracking activity performed by the GSN.

Objects Observed

The total number of unique space objects that have been tracked.

This includes:

  • Active satellites

  • Inactive satellites

  • Debris

  • Rocket bodies

State Vectors Generated

The number of orbital state vectors calculated from observational data.

State vectors describe the precise position and velocity of space objects.


30-Day Lookback Metrics

This section provides performance analytics for the past 30 days.

Average Position Uncertainty

This metric measures the average uncertainty in object position estimates.

Lower uncertainty indicates more accurate orbital tracking.


Daily Tracks per Object

Shows how frequently objects are tracked by the network.

Higher tracking frequency improves:

  • Orbit determination

  • Collision prediction

  • Operational awareness


Average Latency Maintained

Displays the average time between an observation being collected and the resulting data becoming available.

Latency is measured across:

  • LEO

  • GEO

  • All regimes

Lower latency supports faster operational decision-making.


Objects Tracked

The Objects Tracked visualization shows the proportion of catalog objects that are successfully identified.

Categories inc

lude:

  • Identified objects – objects matched to a known catalog entry

  • Unidentified objects – objects detected but not yet fully identified

This metric helps measure catalog completeness and tracking confidence.


Active Catalog Payload Coverage

This visualization shows the percentage of active satellites with tracking coverage across different orbital regimes.

Coverage categories include:

  • LEO (Low Earth Orbit)

  • GEO (Geostationary Orbit)

  • All regimes combined

The chart also differentiates between:

  • GSN coverage

  • Department of Defense (DoD) coverage

This comparison helps evaluate the combined tracking visibility provided by commercial and government sensors.


State Recency

The State Recency chart indicates how recently orbital data has been updated for tracked objects.

Data is categorized by recency windows such as:

  • Less than 12 hours

  • 12–24 hours

  • 1–2 days

  • 2–5 days

  • 5–30 days

More recent updates indicate higher tracking fidelity and operational awareness.


How the GSN Supports Space Domain Awareness

The Global Sensor Network enhances space domain awareness by:

  • Providing global observational coverage

  • Improving catalog completeness

  • Increasing tracking frequency

  • Reducing data latency

  • Detecting orbital anomalies and maneuvers

By combining commercial sensors with Slingshot Global Sensor Network(SGSN) data, the platform delivers a comprehensive view of activity across Earth orbit.
