A C/A (Clear and Aquisition) code single channel Global Positioning System (GPS) receiver (Rockwell/Collins Navcore 1) was installed in the Do-228. This paper describes GPS/DGPS accuracies during approach and landing of the aircraft. All data in which GDOP (Geometric Dilution Of Precision) is less than five are divided into three cases: (1) stand-alone navigation with SA; (2) differential navigation with SA; and (3) stand alone navigation without SA tested on January 1991. Stand-alone accuracy is 75 meters and differential accuracy is 35 meters. Although stand-alone navigation accuracy under no SA is 20 meters, that is because the receiver's specific errors are more than common errors. The effectiveness of DGPS under SA was demonstrated flight experiments.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
