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: "Intellectual 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, including 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) 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 in part 1 [1].
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
provisions).
"must" and "must not" are NOT allowed 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 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 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 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 manufacturers and service providers.

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 telecommunication networks in order to
deliver location-based services to users. As a consequence the present document is not applicable to GNSS only
receivers.
The present document specifies the procedures for testing conformance of complex GNSS based Location System
(GBLS) with the performance requirements specified in ETSI TS 103 246-3 [3].
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
