Foreword

14、 This Technical Specification (TS) has been produced by ETSI Technical Committee Satellite Earth Stations and Systems (SES). The present document is part 5 of a multi-part deliverable covering GNSS-based Location Systems (GBLS), as identified below: Part 1: “Functional requirements“; Part 2: “Refere

15、nce Architecture“; Part 3: “Performance requirements“; Part 4: “Requirements for location data exchange protocols“; Part 5: “Performance Test Specification“. Modal verbs terminology In the present document “shall“, “shall not“, “should“, “should not“, “may“, “need not“, “will“, “will not“, “can“ and

16、 “cannot“ are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of provisions). “must“ and “must not“ are NOT allowed in ETSI deliverables except when used in direct citation. Introduction The increasing proliferation of location-based services

17、is based on several trends in user applications and devices; these include notably the widespread adoption of multi-functional smart-phones, etc., and the wider adoption of tracking devices (e.g. in transport). This need for new and innovative location-based services is generating a need for increas

18、ingly complex location systems. These systems are designed to deliver location-related information for one or more location targets to user applications. The wide spectrum of technical features identified in ETSI TR 103 183 i.1 calls for a new and broader concept for location systems, taking into ac

19、count hybrid solutions in which GNSS technologies are complemented with other technology sensors to improve robustness and the performance.

20、th the Performance Requirements specified in ETSI TS 103 246-3 3.

The tests are defined for laboratory testing only, and not in the “fi

The Integrity func

Specifically, a location system is required to deliver a warning (an alert) of any malfunction (as a result of a set alert limit being

42、exceeded) to users within a given period of time (time-to-alert). Related to the Integrity concept, a Loss of Integrity event occurs when an unsafe condition occurs without annunciation for a time longer than the time-to-alert limit. integrity risk: risk that the positioning error is greater than th
