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. ETSI ETSI TS 103 246-5 V1.1.1 (2016-01)7 1 Scope The present document specifies the procedures for testing conformance of a GNSS-based Location System (GBLS) wi
20、th the Performance Requirements specified in ETSI TS 103 246-3 3. The tests specified are of a complete GBLS, considered as “Black Box“ i.e. the tests are made at outputs of the system in response to stimuli applied at the inputs. The tests are defined for laboratory testing only, and not in the “fi

Related to the Continuity concept, a Loss of Continuity occurs when the user is forced to abort an operation du

The Integrity func
41、tion includes the ability of the location system to provide timely and valid warnings to users when the system does not fulfil the condition for intended operation. 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
