The information pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found in ETSI SR 000 314: “In
22、tellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in respect of ETSI standards“, which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web server (https:/ipr.etsi.org/). Pursuant to the ETSI IPR Policy, no investigation, in
23、cluding IPR searches, has been carried out by ETSI. No guarantee can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web server) which are, or may be, or may become, essential to the present document. Foreword This Technical Specification (TS)
24、 has been produced by ETSI Technical Committee Satellite Earth Stations and Systems (SES). The present document is part 4 of a multi-part deliverable covering GNSS-based Location Systems (GBLS), as identified in part 1 1. Modal verbs terminology In the present document “shall“, “shall not“, “should“
25、, “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 provisions). “must“ and “must not“ are NOT allowed in ETSI deliverables except when used in direct citation. Intro
26、duction The increasing expansion of location-based applications aims to satisfy more and more complex and diversified user requirements: this is highlighted for example by the widespread adoption of multi-functional smart-phones or by the ever wider adoption of tracking devices (e.g. in transport),
27、etc. This requirement for new and innovative location-based applications is generating a requirement for increasingly complex location systems. The wide spectrum of location-based applications identified in ETSI TR 103 183 i.1 calls for a new and broader concept for location systems, taking into acc
28、ount solutions in which GNSS technologies are complemented with other technologies to improve robustness and performance. The notion of GNSS-based location systems is introduced and defined in the present document. Additional clauses and information related to the implementation in GNSS-based locati
29、on 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 manufacturers and service providers. ETSI ETSI TS 103 246-4 V1.2.1 (2017-03)7 1 Scope This multi-part deliverable addresses integrated GNS
30、S based location systems (GBLS) that combine Global Navigation Satellite Systems (GNSS), with 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
31、. This multi-part deliverable proposes a list of functional and performance requirements and related test procedures. For each performance requirement, different classes are defined allowing the benchmark of different GBLS addressing the same applications. The present document defines the requiremen
32、ts for data elements that may need to be exchanged within the GBLS and externally to applications using the GBLS. The present document also specifies data exchange models for these data elements which may form the basis of protocols (or for modification of protocols) and which may be used for the ex
33、change of location-related data within complex GBLS, as well as between the GBLS and external applications. The present document defines the procedures and messages associated with these data exchange models. The GBLS data exchange models are defined to be independent of their underlying transport m
34、echanisms. Nevertheless, on certain GBLS interfaces, transport protocols are recommended. 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.
