In the context of engineering design, flexibility refers to the ability of a system to respond to potential internal or external changes affecting its value delivery, in a timely and cost-effective manner.
Indicators of Flexibility
It follows a list of possible flexibility indicators for a software-defined GNSS receiver:
- Possibility to either use synthetically generated or real-life GNSS signals.
- Possibility to process signals either in real-time or in post-processing time (only limited by the computational capacity of the processing platform executing the software receiver).
- Possibility to use interchangeable RF front-ends.
- Possibility to define custom receiver architectures.
- Possibility to easily define / interchange implementations and parameters for each processing block.
- Possibility to change parameters while the software is executing.
- Possibility to be executed in different processing platforms (mainframes, personal computers, embedded systems, etc).
- Availability of a versatile configuration mechanism.
- Availability of operation modes, as combinations of:
- Single / multiple frequency bands.
- Single / multiple constellations.
- Stand-alone / assisted / differential GNSS.
