Foreword This Technical Specificat
17、ion (TS) has been produced by ETSI Technical Committee Satellite Earth Stations and Systems (SES). The present document is part 1 of a multi-part deliverable covering the GNSS based location systems, as identified below: Part 1: “Functional requirements“; Part 2: “Reference Architecture“; Part 3: “P
18、erformance requirements“; Part 4: “Requirements for location data exchange protocols“; Part 5: “Performance Test Specification“. Introduction The increasing expansion of location-based applications aims to satisfy more and more complex and diversified user requirements: this is highlighted for examp
19、le by the widespread adoption of multi-functional smart-phones or by the ever wider adoption of tracking devices (e.g. in transport), etc. This requirement for new and innovative location-based applications is generating a requirement for increasingly complex location systems. The wide spectrum of l
20、ocation-based applications identified in ETSI TR 103 183 i.1 calls for a new and broader concept for location systems, taking into account solutions in which GNSS technologies are complemented with other technologies to improve robustness and performance. The notion of GNSS-based location systems is
21、 introduced and defined in the present document. Additional clauses and information related to the implementation in GNSS-based location systems of the various differential GNSS technologies, namely D-GNSS, RTK and PPP are also included in order to facilitate the use of this set of standards by manu
22、facturers and service providers. Modal verbs terminology In the present document “shall“, “shall not“, “should“, “should not“, “may“, “need not“, “will“, “will not“, “can“ and “cannot“ are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of pro
23、visions). “must“ and “must not“ are NOT allowed in ETSI deliverables except when used in direct citation. ETSI ETSI TS 103 246-1 V1.2.1 (2017-03)5 1 Scope This multi-part deliverable addresses integrated GNSS based location systems (GBLS) that combine Global Navigation Satellite Systems (GNSS), with
24、 other navigation technologies, as well as with telecommunication networks in order to deliver location-based services to users. As a consequence the present document is not applicable to GNSS only receivers. This multi-part deliverable proposes a list of functional and performance requirements and
25、related test procedures. For each performance requirement, different classes are defined allowing the benchmark of different GNSS Based Location Systems (GBLS) addressing the same applications. The requirements herein are intended to address the growing use of complex location systems required for t
26、he provision of location-based applications particularly for the mass-market (refer to ETSI TR 103 183 i.1). The present document defines the functional requirements applicable to location systems, based on a summary of types of applications relying on location-related data provided by location syst
27、ems. The present document can be considered as the Stage 1 characterization of location systems according to the ITU/3GPP approach i.2. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
