Satellite Mission Simulator

Simulate the mission before it becomes an operation

GSMS is the GMSPAZIO simulator designed to evaluate the behavior of a satellite system from a mission-level perspective.

It allows for the analysis of operational scenarios, system performance, real-world constraints, planned activities, and acquisition processes, using 2D and 3D environments to make the mission clearer, measurable, and comparable.

System Introduction

From satellite simulation to mission evaluation

A satellite mission does not depend on the orbit alone. The target, payload, acquisition window, user priorities, scheduling, downlink, ground stations, operational constraints, and the time required to transform a task into available data all matter.

GSMS was created to interpret these elements together. The tool allows for the simulation of the entire satellite system behavior, evaluation of mission performance, and comparison of different scenarios before operational deployment.

Mission types

More realistic operational scenarios

GSMS supports two main analysis modes: System Performance Analysis and Planner-Scheduler Analysis.

The first measures the overall performance of the satellite without user constraints. The second evaluates the mission under conditions closer to operational reality, including priorities, task scheduling, multiple requests, and usage quotas.

Evaluates the mission with real-world constraints, user priorities, and scheduled activities.
Manages multiple requests, priorities, and operational quotas.
Simulates the complete process, from task uplink to acquisition, through to downlink and processing.

Assets and payloads

Configurable missions, targets, and constraints

GSMS allows for the configuration of satellite scenarios with different targets, areas of interest, and operational constraints.

The tool supports point targets, AOIs, latitude belts, and region lists, allowing the mission to be evaluated against specific objectives.

Analysis can include constraints such as Solar Zenith Angle, time delay, system operating modes, data rates, and selected ground stations.

  • Configurable Targets
    Analysis of points, areas of interest, latitude belts, and regions.

  • Operational Constraints
    Mission evaluation with parameters such as SZA, time delay, and operating modes.

  • Ground Stations and Downlink
    Analysis of the data download process based on available stations.

  • Mission-Level Scenario
    Integrated representation of assets, tasks, acquisition, and data availability.

Outputs and metrics

Understanding how the mission actually performs

GSMS transforms simulation into useful metrics for operational evaluation.

The tool measures response times, revisit time, and information age, helping to understand how effective a mission is relative to the required objectives.

Visualizes and documents planned activities, including order ID, uplink time, acquisition period, and downlink details.

Integrations

2D and 3D environment to interpret the mission

GSMS is built on the AGI STK platform and customized by GMSPAZIO to offer an immersive mission-level simulation environment.

Scheduled activities can be viewed in 2D and 3D graphical modes, while results can be exported via comprehensive text reports.

The value is not just in seeing the mission. It is in understanding how performance changes when targets, constraints, priorities, ground stations, or time windows change.

  • 2D and 3D Visualization
    Graphical representation of mission activities.

  • Text Reports
    Comprehensive reports on scheduled activities and operational details.

  • Scenario Comparison
    Comparison between configurations, constraints, and results.

  • Operational Workflow
    Connection between planning, acquisition, download, and performance evaluation.
