In satellite mission planning, the right tools can make all the difference between theoretical feasibility and actionable strategy. Satellite mission simulation platforms are critical across industries—from defense surveillance to Earth observation. These tools support a variety of applications from precise trajectory calculations, orbital maneuver planning, and constellation optimization to ensure effective data capture and seamless ground communication. Ultimately, mission design platforms boost operational efficiency, reduce risks, and enhance strategic satellite deployment.
Teams working on satellite missions often rely on a range of customized solutions and homegrown tools for scripting with in-depth analysis. Robust simulation tools like JOURNEY play a unique role by providing fast, iterative concept-of-operations (con-op) assessments. These tools ensure that when it’s time to scope a mission, mission planners can do so with a clear direction, knowing they’re are solving the right problems from the start.
JOURNEY is a comprehensive mission design, simulation, and analysis tool developed to help users efficiently plan and optimize their missions. It features the Preliminary Mission Design (PMD) module, which allows users to quickly simulate and match with subsystems like propulsion, ADCS, power, and communications based on high-level mission inputs. Additionally, the Advanced Mission Design (AMD) module supports high-fidelity simulations for both single satellite and constellation missions, offering detailed insights and visualizations of orbital element evolution, delta-v, power consumption, and ground asset interactions throughout the mission. These capabilities enable users to effectively refine their missions throughout all stages of the mission design lifecycle.
Key Mission Applications for JOURNEY
Target Collection Feasibility & Frequency Analysis
When planning a satellite mission, it’s critical to understand how often a satellite can collect data from specific targets over a defined time period. JOURNEY allows mission planners to perform feasibility analysis for data collection by using comprehensive metrics such as revisit rates, gap times, pass durations, look angles, look directions, and total data volume. This ensures that satellite constellations are optimally designed to meet mission objectives, providing a clear picture of how frequently targets can be observed and how much data can realistically be collected.
Ground Contact Statistics Analysis
Ground station communication is key to any satellite mission. JOURNEY enables users to analyze the frequency and duration of satellite contacts with ground stations along with other key performance metrics like look angle, look duration, total data volume and ground track visualization. This helps operators ensure reliable and efficient ground communication throughout the mission.
Mission Propulsion Sizing Planning
Propulsion sizing is a crucial aspect of mission design, determining the amount of fuel or thrust required to achieve mission objectives such as orbital insertion or station-keeping. With JOURNEY, users can calculate propulsion requirements based on mission parameters like orbital altitude, satellite mass, and maneuver schedules. This allows mission planners to optimize propulsion systems for efficiency, ensuring that the spacecraft has enough thrust to meet its operational goals without over-sizing or under-sizing the propulsion system.
Mission Power Budget Planning
Understanding power consumption is essential to maintaining satellite operations over the mission lifecycle. JOURNEY provides tools to model power consumption requirements for various mission phases, including active operations, communications, and payload activity. By analyzing power draw from onboard systems and power available from solar panels and battery pack, users can optimize power budgets, ensuring that satellites remain operational throughout the mission without exceeding their power limits or jeopardizing mission objectives.
JOURNEY's Role in Streamlining Satellite Operations
The satellite industry faces a growing demand for tools that support precise mission design, data capture, and efficient resource management. With increased complexity in mission requirements, engineering teams often work with a mix of customized tools and in-depth scripting solutions to perform detailed analyses. However, this patchwork approach can be time-consuming, especially when fast, iterative modeling is needed for decision-making. For these teams, balancing high fidelity in their simulations with practical, efficient tools is key to reducing operational risks and refining mission strategies in real time.
JOURNEY offers a practical balance of accessibility and advanced capabilities. Designed with advanced constellation tools—including geometric and multi-objective optimization—JOURNEY enables precise constellation planning to meet specific mission goals. Its automated analytics offer key insights into satellite performance, ground station contacts, and target collection without the need for complex configurations, allowing engineers to focus on mission objectives directly.
JOURNEY’s intuitive interface and streamlined workflows simplify mission planning and execution, making it a scalable, cost-effective choice for satellite operations. With these powerful tools, mission planners can conduct trade studies, optimize configurations, and achieve their mission goals confidently and efficiently.
Constellation Design: JOURNEY's Constellation Designer features three geometric designs (Walker Delta, Walker Star, and Streets of Coverage) for seamless global or zonal coverage, along with a powerful multi-objective optimized constellation designer that tailors constellations to specific goals like maximizing coverage or minimizing gap times. These advanced options set JOURNEY apart from several other constellation design tools that exist in the market.
Ground Station & Target Analytics: JOURNEY's recent updates to Ground Station contacts and Target collect analytics enable users to easily access detailed metrics, including revisit rates, look angles, pass duration, and data volume. Unlike other mission design platforms that require extensive customization to generate such insights, JOURNEY simplifies the process by offering these key analytics as default outputs, reducing the setup burden for users
Subsystem Matching: One of JOURNEY's unique features is its ability to automatically identify suitable subsystems from a library of over 400 integrated satellite components. This capability streamlines the process of selecting the right components for satellite missions, significantly reducing the time and effort required for mission design.
Ease of Use: JOURNEY’s intuitive user interface and built-in workflows, designed specifically for satellite missions, distinguish it from many other mission tools on the market that often have steep learning curves and require expert-level knowledge.
Cost-Effectiveness: JOURNEY is designed to deliver high-level capabilities at a significantly lower cost. Annual licensing cost of other existing platforms, especially for full mission design capabilities, can exceed $130,000 annually, whereas JOURNEY offers a more accessible pricing structure for teams looking for a focused, efficient satellite mission planning tool.
By combining advanced automation, multi-objective optimization, and a user-friendly interface, JOURNEY stands out as the go-to platform for satellite operators and engineers who need reliable tools without the complexity and high costs associated with broader mission design software.
