Integration of Software Receiver with
Enhanced Integrity Concept on PDA for Safety
Handheld Applications (SOPHA)
Development of a GNSS software receiver, running on a lightweight PC platform.
The purpose of the project SOPHA is to integrate a unique GNSS software receiver on a modern lightweight
PC platform (e.g, on a Personal Digital Assistant) with augmentation sensors to support the navigation solution
with integrity and a feasibility study of a WLAN update concept. The project will demonstrate its capabilities for
personal mobility applications in unfavourable environment such as urban canyons or mountainous regions.
The technical approach will be based on state-of-the-art and innovative emerging technologies from European SME
companies which will be adapted, upgraded and modified to satisfy the user requirements for new Galileo technologies
and future navigation needs for personal mobility.
