SVEQ - GNSS Receiver SW Verification & Qualification Framework
All elements of a spaceborne GNSS (Global Navigation Satellite System) receiver are ultimately united by the receiver software. Almost each and every hardware and/or system change will result in software modifications, in turn comprising design, implementation and test, as a consequence. The effort to test and qualify spaceborne software systems with these stringent requirements in terms of functionality, reliability and maintainability is normally in the range of 50% of the complete software development life-cycle.
The present activity aims at supporting inevitable product evolution by providing a framework for Software Verification and Qualification (VQ), implementing it in Austrian Aerospace’s (AAE’s) GNSS-receiver software and demonstrating its suitability by applying it to the transition from a receiver providing on-board spacecraft navigation functionality to a qualified scientific precise orbit determination instrument.
In the course of this study the receiver software architecture is optimized with respect to integrated qualification capabilities, and software qualification platforms are established facilitating verification/qualification of an evolutionary product software. The study is part of AAE’s Product Development Program, aiming at the establishment of a product line of Spaceborne GNSS Receivers.
The activity is conducted in an international co-operation with Saab Space in Sweden, which provides essential test evaluation tools for the verification and qualification tests of GNSS receiver software.
