Software Development for
the Aerospace Industry
Qwasaa supports aerospace companies in
continuously and reliably developing established software systems.
Software in aerospace must do more than provide functionality. It has to remain maintainable over long lifecycles, process technical data in a traceable way, and adapt to new requirements in a controlled and reliable manner. Qwasaa supports companies in the targeted evolution of existing software systems — with experience in system-level development, embedded software, visualization, device integration, and long-lived codebases.
Our strength lies in structuring complex technical systems clearly, integrating changes cleanly, and developing software that remains reliable in operational environments.
Reliable Software for Long-Lived
Technical Systems
Aerospace systems are designed to remain in use for many years — often decades. While many of these systems run reliably, every change must be implemented in a controlled, traceable way and without unintended side effects. New requirements, interfaces, extensions, or adaptations to existing components often meet evolved architectures, limited hardware resources, and demanding expectations regarding timing behavior, stability, and traceability.
Qwasaa helps you further develop existing software in a structured and controlled way — within your established architecture and technical constraints. Our expertise covers system-level software development, long-lived codebases, embedded software, supporting device software, visualization, and the integration of technical systems – for example with C, C++, Ada, Qt, .NET, Qt for MCU and Embedded Linux.
We develop, modernize, and implement software solutions that integrate cleanly into existing technical environments.

The result:
- more predictable changes
- more stable releases
- software that performs reliably even in complex system environments
Software Across the
Technical Value Chain
Aerospace systems are built across several closely connected layers:
- Sensors and data acquisition
- Firmware, drivers, and device-level software
- Processing, evaluation, and algorithmic interpretation of measurement and status data
- Visualization and user interaction
- Desktop or mobile applications for device support
- Integration into higher-level systems
- Operation, maintenance, analysis, and documentation
These layers are tightly interlinked. Changes in one area often affect other components.
Typical challenges include:
- Data must remain consistent across multiple systems
- Information is used in different contexts, such as operation, analysis, service, or testing
- Software continues to evolve over many years
- Existing hardware, interfaces, and certifications define clear technical boundaries
- Data must be processed within defined time windows
- New features need to be integrated into existing architectures in a controlled and reliable way
For us, software engineering means making complexity manageable – and implementing changes in a way that integrates cleanly into existing systems. Qwasaa helps you create and evolve exactly this structure.
Typical Challenges in Aerospace Software Development
Aerospace software is rarely developed from scratch. In many cases, the focus is on extending existing systems reliably,
integrating new requirements cleanly, and keeping technical dependencies transparent and traceable.
Many teams face similar challenges:
- Systems have grown over many years and are difficult to oversee
- Changes must remain stable and maintainable across long lifecycles
- Dependencies between components are complex
- Data must be processed consistently, traceably, and within reliable timing constraints
- Updates must not unintentionally affect existing functionality
- Hardware resources are limited and cannot be scaled arbitrarily
- Testing, analysis, and validation processes must remain reproducible
For development teams, this means that every change needs to be planned,
implemented, and verified with technical precision.
For business and technical departments, it means that information must be
reliably available, clearly presented, and usable for analysis, service, or documentation.
Qwasaa operates exactly at this intersection:
between system-level software development, technical integration, and the clear, practical use of complex data.
How Qwasaa supports you
We help you further develop existing software in a targeted way and modernize where technical debt, new requirements, or growing system complexity make maintenance more difficult. In doing so, we take your existing architecture, hardware limitations, interfaces, data flows, and release processes into account.
Qwasaa implements changes in a traceable and well-coordinated way. New features are not viewed in isolation, but in the context of the entire system: Which components are affected? Which data is required? Which dependencies exist? Which side effects need to be avoided?
We connect components, data sources, applications, and devices to create consistent, reliable workflows. This includes sensors, subsystems, existing applications, databases, desktop applications, mobile apps, cloud or IoT environments, and higher-level system landscapes.
Testing, reviews, and structured development processes help ensure stable and reproducible results. Especially in long-lived technical systems, quality assurance is not a downstream step — it is an integral part of the development process.
We implement changes in a way that makes them technically verifiable and suitable for downstream testing and validation processes. We ensure that evaluations remain reproducible, data flows stay traceable, and new features are integrated into existing systems in a controlled and reliable manner.
Embedded Software Development and Supporting Device Software
In aerospace, software development often starts directly at the device level. Sensors, control units, measurement systems, and technical components must operate reliably, capture data correctly, and provide information in a defined and consistent format.
Qwasaa develops embedded software and supporting device software for technical systems with demanding requirements. We work with devices that run a full operating system, a lightweight operating system, or operate under highly constrained resources.
Our expertise lies in connecting hardware-oriented software development with the supporting application layer.
This includes:
- Embedded software running directly on the device
- Firmware-related development and algorithms
- Driver development and interface integration
- Desktop and mobile applications for device support
- Device interaction and device integration
- Visualization of measurement, test, and status data
- Development with Qt, .NET, Qt for MCU, and Embedded Linux
- Integration with databases, IoT environments, cloud systems, and existing backend landscapes
We develop software that does more than operate devices: it makes their data usable for testing, analysis, documentation, maintenance, and automation.
Typical Use Cases for Software
Aerospace software is used wherever technical data needs to be processed, visualized, or reused reliably.
Typical use cases include:
- Processing, evaluation, and algorithmic interpretation of sensor and system data
- Visualization of complex system states for analysis and operation
- User interfaces for technical systems
- Embedded software and firmware-related development
- Supporting desktop and mobile applications for devices
- Integration of components into higher-level systems
- Automation of testing and validation processes
- Digital capture and evaluation of test protocols
- Structured storage and historization of technical data
- Consolidation of data from devices, applications, and existing systems
- The goal is not to extend systems unnecessarily. What matters is developing exactly the functionality
that makes technical workflows safer, more traceable, and easier to maintain.
Technologies and System Environment
We work in the environments in which these types of systems are typically built:
- CC and C++ for system-level and highly integrated software
- Ada for safety-critical and long-lived system contexts
- Qt for visualization, user interfaces, and device-level applications
- Qt for MCU for lightweight graphical applications on resource-constrained devices
- C# / .NET for applications, services, and system integration
- Embedded Linux for device-level software platforms
- Algorithmic and deterministic processing of technical data
- Integration of components via communication and bus systems — from CAN-based networks to specialized networks such as SpaceWire
- Interfaces to machines, sensors, databases, cloud systems, and existing applications
- Evolved system landscapes and long-lived codebases
For us, software engineering means making technical decisions that fit the existing environment. We do not develop around your system reality. We take your existing architecture, data structures, interfaces, hardware limitations, and operational requirements into account from the very beginning.
Why work with Qwasaa?
When technical systems grow over many years, standard software is often not enough. At the same time, rebuilding an entire system from scratch is often neither economically nor technically sensible. Qwasaa works exactly within this field of tension. We develop, modernize, and integrate software solutions for technical systems in which existing applications, devices, data sources, and processes need to work together reliably.
This gives you clear benefits:
- Controlled advancement of existing systems
- Risk reduction during changes and enhancements
- Traceability of data flows
- Improved maintainability and increased release stability
- Seamless integration of devices, applications, and data sources
- Gradual automation of testing, evaluation, and documentation processes
- Retention of usable legacy systems
- Establishment of technical foundations for further digitization and automation
Our target is not to make systems unnecessarily complex. Our goal is to develop software that works under real-world technical conditions, remains understandable, and noticeably reduces the burden on your teams.
