22、d in ETSI deliverables except when used in direct citation. Introduction 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
23、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 location-based applications identified in i.1 calls for a new and broa
24、der 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 introduced and defined in this standard. Additional clauses and information related
25、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 manufacturers and service providers. Hence a set of standards for GNSS-based Location systems is
26、 defined of which the present document is part 2. ETSI ETSI TS 103 246-2 V1.2.1 (2017-03)6 1 Scope This multi-part deliverable addresses integrated GNSS based location systems (GBLS) that combine Global Navigation Satellite Systems (GNSS), with other navigation technologies, as well as with telecomm
27、unication 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 related test procedures. For each performance requiremen
28、t, different classes are defined allowing the benchmark of different GNSS Based Location Systems (GBLS) addressing the same applications. The architecture specified herein is a “functional“ architecture, meaning that the system is defined in terms of discrete functional elements connected to other i
29、nternal or external functional elements via associated “logical“ interfaces. These functional elements and interfaces are derived from service requirements. The functional architecture is not necessarily related to the “physical architecture“ (i.e. the relationship between equipment which may implem
30、ent all or some of these functions, and the physical interfaces between them). The present document can be considered as the Stage 2 functional specification according to the ITU/3GPP approach i.4. 2 References 2.1 Normative references References are either specific (identified by date of publicatio
