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

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

AEROTHAI 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 1)Assess single frequency GPS performance 2)Assess single frequency GPS + SBAS performance 3)Assess multiple frequency GPS performance 4)Assess multiple frequency GPS + SBAS performance 5)Observe and record ionospheric characteristics in the APEC test bed region.  Performance Test Goals 2006/TPT-WG-28/IEG/002_v2

AEROTHAI * 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.  Test Cases 2006/TPT-WG-28/IEG/002_v2
