Demonstrating a GPS/EGNOS/Loran-C navigation system in difficult environments as part of the ESA project SHADE

摘要

The ESA-funded project "Definition and Demonstration of Special Handheld based Applications in Difficult Environment" (SHADE) addresses novel applications in the non-transport sector that improve availability, accuracy, and reliability of continuous positioning solutions in dense urban and indoor environments. Thus, SHADE provides safety and security enhancements for personal mobility applications. Within the project, three independent mobile demonstrators are built, demonstrated, and evaluated towards their applicability in the mentioned environments. The mobile units are: 1. A-EGNOS: Assisted-GPS receiver including EGNOS functionality; 2. Sensor augmented EGNOS: Inertial navigation sensors and GPS, including EGNOS functionality; 3. GPS/EGNOS/Loran-C: Integrated GPS/Loran-C navigation system, including EGNOS functionality. In addition to the development and testing of these mobile units, the SHADE project also aims at developing a so-called "Mission Centre" architecture. The task of the Mission Centre is to display positions and other information related to mobile units within animated 3D models. The Mission Centre software can therefore be used at a command post during rescue missions for coordinating mobile rescue teams.
