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 below:
Part 1: "Functional requirements";
Part 2: "Reference 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
"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 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
increasingly 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 account hybrid solutions in which GNSS technologies are complemented with other
technology sensors to improve robustness and the performance.

1 Scope
The present document specifies the procedures for testing conformance of a GNSS-based Location System (GBLS)
with 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 "field".

3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in ETSI TS 103 246-1 [1] and the following
apply:
accuracy (or error): difference between a measured or estimated value and its real value
almanac: information providing coarse orbit and coarse clock model information for GNSS satellites. Database
providing location information for a reference network used for positioning
assistance: use of position data from, typically, a telecommunications network to enable a GBLS receiver to acquire
and calculate position more quickly (e.g. A-GNSS)
availability: measures percentage of time when a location system is able to provide the required location-related data
class A, B, C: classes categorize the performance level of the GBLS for a given performance feature
NOTE: In all cases Class A is the highest performance class and C is the lowest.
cold-start: condition of the GBLS GNSS receiver having no accurate prior information on the position, velocity and
time of the location target, or on the positions of any of the GNSS satellites
continuity: likelihood that the navigation signal-in-space supports accuracy and integrity requirements for duration of
intended operation
NOTE: Continuity aids a user to start an operation during a given exposure period without an interruption of this
operation and assuming that the service was available at beginning of the operation. Related to the
Continuity concept, a Loss of Continuity occurs when the user is forced to abort an operation during a
specified time interval after it has begun (the system predicts service was available at start of operation).
continuity risk: probability of detected but unscheduled naviga
