Satellite Risk Management

Successfully placing a satellite into space requires the seamless integration of multiple complex processes, ensuring an on-schedule launch and nominal operations once the satellite is in orbit. Modern government organizations and private companies have honed this intricate process, resulting in regular space launches worldwide. Despite their high success rates, satellite programs remain fraught with risk—from drafting requirements to issuing the "ready-for-launch" command.

This essay will explore Risk Management Techniques within Technical Management Processes, specifically concerning satellite programs. Drawing on real-world satellite program examples, the discussion will illuminate various aspects surrounding the Risk Management processes.

Introduction to Risk Management in Satellite Programs

To tackle the inherent risks in complex satellite programs, it is crucial first to define what risks entail and what risk management encompasses. Risks represent opportunities that suggest potential hazards, leading to possible loss of something valuable. In project terms, risk signifies the possibility of an event affecting project objectives negatively or positively. Although positive risks occasionally arise, the majority are typically negative. Given the substantial financial investments in satellite programs—ranging from $5 million for smaller satellites to multi-billions for advanced Department of Defense satellites—risk management becomes essential. It involves the art and science of identifying, analyzing, and addressing risks throughout a project's lifespan to achieve end objectives.

When analyzing risks, uncertainty must also be accounted for. It is imperative to distinguish between risk and uncertainty. Uncertainty refers to a lack of certainty, where outcomes or consequences are unknown or immeasurable due to a lack of background information or context. Conversely, risk allows for an analysis of potential outcomes or consequences, determining the likelihood of specific outcomes. For instance, consider a football game between the Miami Dolphins and the New England Patriots. While predicting the winner with 100% confidence is impossible, an educated guess can be made based on past performances, player strengths, and the game's location. This scenario exemplifies risk analysis. In contrast, if the teams were unnamed and the venue unknown, making an educated guess is impossible due to the lack of contextual information—this represents uncertainty.

Risk Management Techniques

In managing risks and seeking to "burn down" risk, several established techniques are employed across satellite program management and project management. These techniques include risk avoidance, risk mitigation, risk acceptance, and risk transference. Risk avoidance involves circumventing a presented risk altogether. Risk mitigation seeks to reduce the likelihood of a risk occurring or lessen its consequences. Risk acceptance involves acknowledging a risk as part of the project and proceeding with it understood. Risk transference shifts responsibility for a risk to a third party, absolving the original party or team.

Understanding risk, uncertainty, risk management, and its techniques is crucial for applying these concepts in satellite programs. With this foundation, let's explore different types of satellite systems, their functions, and the risks associated with their lifecycle. Satellite systems vary widely, with functions ranging from communications and navigation to remote sensing and exploration. Additionally, these satellites operate in one of four orbital domains: LEO (low-Earth orbit), MEO (medium-Earth orbit), and GEO (includes geostationary and geosynchronous orbits). Depending on a satellite's mission, orbital domain, and intended lifespan, different risks arise throughout its lifecycle.

Real-World Example: FalconSat Program

At the outset of any satellite program, a mission is defined through customer requirements. This mission determination influences satellite construction, operation, and responsible parties. Consider the FalconSat series developed by the U.S. Air Force Academy (USAFA) in Colorado Springs, Colorado. The recently launched FalconSat-6 is a "multi-mode flight experiment" testing fuel-efficient orbit changes, low-energy ion head thrusters, wireless versus wired telemetry, and ionospheric changes. As an R&D satellite, FalconSat tests new technologies in space, often for the first time.

The USAFA's astronautics department uses FalconSat as a capstone project for cadets, relying on their coursework for research and calculations. The cadets' lack of experience introduces a risk, as calculation errors or assembly mistakes could be detrimental or catastrophic. Recognizing this risk, the USAFA partners with experienced organizations like Air Force Research Labs, NASA, and the National Reconnaissance Office. These partnerships exemplify risk mitigation, as they aim to reduce the likelihood of errors due to cadet inexperience. Government agency partners provide oversight to ensure the system's adherence to standards.

While risk avoidance is impossible, as cadet involvement is integral to the capstone, risk transference is also inapplicable since USAFA is a government institution. However, risk acceptance is relevant; despite mitigation efforts, some risk remains due to cadet involvement. The continued development of FalconSat systems indicates the government's acceptance of this risk.

Exploration of Risk Transference

Another significant risk in R&D systems is the possibility of failing to meet objectives. FalconSat's first-of-kind technologies necessitate risk acceptance to proceed with fielding the system. Risk mitigation can only address validated aspects of the system. Risk transference is unlikely due to the project's governmental nature, and risk avoidance is inapplicable; the mission requires assuming operational risks.

Risk transference, the concept of delegating risk to a third party, often involves space insurance. Space insurance transfers fiscal risks from the insured to the insurer, covering production to operations phases. This safeguard protects against financial repercussions from catastrophic events, such as launch failures. Space insurance is particularly vital, given the potential repercussions of space system disasters, including environmental and human safety concerns.

Consider a hypothetical rocket with a commercial communications payload. If the rocket explodes at launch, debris could pose significant risks, as seen in a 1996 launch catastrophe in China. The destroyed satellite would lead stakeholders to seek compensation from the launch company. Space insurance allows stakeholders to transfer fiscal risks to insurers, safeguarding against financial losses.

Reputation, however, remains outside risk management plans. Companies like SpaceX balance occasional failures with success milestones, maintaining stakeholder trust. Conversely, companies with frequent failures risk losing business and potential shutdown, as seen with America Rocket Company.

Risk Management in Satellite Communications

Risk management extends to satellite communications, covering development and post-launch phases. Post-launch involves separation from the launch vehicle, system deployment, initialization, and OT&E. Communication relies on ground or on-orbit relays, managed by operations crews. Program managers must consider relay architecture during development, weighing risks of dedicated versus shared relays.

Dedicated relays entail construction, operation, and maintenance costs. If funding is an issue, dedicated relays pose financial risks. Incorrect placement risks operational failure. Shared relays, owned by other organizations, introduce competition for usage and reliance on maintenance schedules. NASA's Tracking Data Relay Satellite System exemplifies shared relays, with R&D users subject to NASA's communications schedule.

Program managers can mitigate communication risks by utilizing multiple relays, brokering agreements with other organizations for emergency use. This approach ensures communication continuity, minimizing operational disruptions.

Conclusion

In conclusion, the successful placement and operation of satellites in space are fraught with risks that require meticulous management. By employing techniques such as risk avoidance, mitigation, acceptance, and transference, satellite programs can navigate these challenges effectively. Real-world examples, like the FalconSat program, illustrate the practical application of these techniques, highlighting the importance of partnerships and risk acceptance in achieving program objectives. As satellite programs continue to evolve, understanding and managing risks will remain vital to ensuring their success and sustainability.
