Summary of the Initial GPS Test Standards Document: ION STD-101

Stewart Teasley and James Bybee

Abstract:	The GPS Test Standards Working Group (WG) was or- ganized in early 1994 to develop a set of performance test standards applicable to marine, vehicular, and handheld commercial GPS receivers. The need for such a standard arose from the inconsistencies seen in the specifications of various GPS receivers and the confu- sion among GPS users in comparing the attributes of these products. ION has sponsored the WG through its Satellite Division and has provided meeting facilities at major ION meetings. This paper summarizes the initial ION STD-101 docu- ment produced by the WG. Each of the key tests de- veloped within the document is described along with the rationale for selecting the tests and the methodolo- gies. An independent validation of the test procedures, data analysis techniques, and data presentation formats of ION STD-101 has been accomplished using the GPS test facilities at the YPG. The results of this validation process are presented along with recommended modifi- cations to the test standard document based on the tests. Plans to enhance the standard through the addition of specific test limits for marine, vehicular, and handheld applications of GPS are outlined. The future activities of the WG and its relationships with other industry or- ganizations are also discussed.
