FIX_8 (High Accuracy Positioning using EGNOS and Galileo Products) Galileo SME Workshop 5 th & 6 th April 2006
Consortium Nottingham Scientific Limited (UK SME) Project Coordinator Management, Prototype Design & Integration, Demonstration and Testing Delft University of Technology (NL University) Department of Earth Observation and Space Systems (DEOS), Faculty of Aerospace Engineering Design & develop new precise positioning algorithm, Demonstration and Testing Finnish Geodetic Institute Department of Navigation and Positioning Input Data Assembly, Demonstration and Testing
Project Rationale Precise Point Positioning (PPP) - high accuracy & operational flexibility [single receiver] Relies on precise satellite orbit and clock data Freely available with latency or in real-time for a fee Broadcast navigation messages are improving (EGNOS, Galileo, GPS Modernisation) Is a 20-30cm PPP solution possible using EGNOS today or Galileo broadcast messages in the future? If so, positioning accuracy can be improved by an order of magnitude with minimal changes to a standard receiver
Objectives Prototype a new PPP solution using EGNOS and Galileo data Examine sensitivity of solution to the accuracy of initial orbit and clock data and operating conditions Minimise convergence time, optimise robustness (availability) Assess performance & compare with alternatives Provide useful integrity/reliability measures Identify options for a future operational solution
Work Plan
Progress Status (1) Initial FIX_8 working with: IGS (final, rapid, ultra-rapid*) GSTB Navigation Messages
Progress Status (2) Consolidation User and system requirements End-to-end architecture design Extrapolation to Galileo Implementation Initial PPP solution implemented by TUD Tools for data preparation developed Enhancing end-to-end SW & integrating PPP Next Comprehensive testing and performance evaluation Include comparisons with alternative solutions Optimise prototype and identify future enhancements
Expected Results (1) Results proving feasibility of FIX_8 concept n Can PPP work with EGNOS + GPS? n Can PPP work with Galileo broadcast messages? Comprehensive Performance Assessment n Performance with Prototype –Archived Datasets –Dedicated Field Tests Plan for taking Prototype Forward Extrapolation to Galileo Possibilities for High Accuracy Galileo Commercial Service
Expected Results (2) Robust Software Prototype
Future Steps (1) Real-time demonstration with FIX_8 in a receiver Probably in a Software receiver initially Apply EGNOS corrections if prototypes shows viability Possible “live” link to Galileo Data (GSTBv2, IOV) Add FIX_8 to simulation tools Accuracy, Integrity, Availability, Continuity Simulate Galileo observations
Future Steps (2) Implement FIX_8 solution in NSL software receiver Possible licensing of FIX_8 receiver algorithms Possible license agreements with service providers Suppliers of Commercial high accuracy services Galileo concessionaire Use FIX_8 as a software tool to investigate new methods of ionospheric and tropospheric modelling
