  8. Asia-Pacific GNSS Test Bed 2006/TPT-WG-28/IEG/002_v2 • Upcoming Events • July – December 2006: Data collection and Flight Test • October 2006: Initial Study Result Reported to APEC GIT 10 • December 2006: Draft Final Report2006: Study report expected 8

  9. 2006/TPT-WG-28/IEG/002_v2 • Performance Test Plan Study report expected 9

  10. Raw data collected by the APEC GNSS Test bed 2006/TPT-WG-28/IEG/002_v2 • L1 and L2 GPS signal and messages • SBAS messages generated by Test Master Station • Trajectory of Flight Test calculated by the TUP 10

  11. Performance Test Goals 2006/TPT-WG-28/IEG/002_v2 • General Goal Assess stand-alone and augmented GPS performance with respect to requirements for civil aviation operations • Accuracy and integrity alert limits • En route through approach-with vertical-guidance operations • System Availability and Continuity of Services • Specific Goals • Assess single frequency GPS performance • Assess single frequency GPS + SBAS performance • Assess multiple frequency GPS performance • Assess multiple frequency GPS + SBAS performance • Observe and record ionospheric characteristics in the APEC test bed region.

  12. Test Cases 2006/TPT-WG-28/IEG/002_v2 * PDR = Pseudorange; ADR = Accumulated Delta Range (carrier range + ambiguity) ** Optional Cases - Data processing is multi-step and more cumbersome to resolve ADR ambiguities, but illustrative of what will be possible when GPS signals at three frequencies are available.
