16、 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 1 of a multi-part deliverable covering the GNSS based location systems, as identified below: Part 1: “Functional re

17、quirements“; Part 2: “Reference Architecture“ Part 3: “Performance requirements“; Part 4: “Requirements for location data exchange protocols“; Part 5: “Performance test specification“. Introduction The increasing proliferation of location-based services is based on several trends in user application

18、s 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 a

19、re designed to deliver location-related data for one or more location targets to user applications. The wide spectrum of technical features identified in i.1 calls for a new and broader concept for location systems, taking into account hybrid solutions in which GNSS technologies are complemented wit

20、h other technology sensors to improve robustness and the performance. Hence a set of standards for GNSS-based location systems is defined, of which the present document is part 1. Modal verbs terminology In the present document “shall“, “shall not“, “should“, “should not“, “may“, “need not“, “will“,

21、 “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.

22、e The present document addresses integrated location systems 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. The requirements herein are intended to address t

23、he growing use of complex location systems needed for the provision of location-based applications particularly for the mass-market (refer to i.1). The present document defines the functional requirements applicable to location systems, based on a synthesis of types of applications relying on locati

24、on-related data provided by location system. 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 numbe

34、ation module: entity in charge of retrieving from a location system the location-related data associated to one or more location targets and processing it in order to deliver to the application user the location based service it has been designed for NOTE: The application module can be located insid

35、e or outside a terminal. authentication: provision of assurance that the location-related data associated with a location target has been derived from real signals associated with the location target NOTE: By extension, authentication is one of the key performance features that can be required to a

36、location system. architecture: abstract representation of a communications system NOTE: Three complementary types of architecture are defined: square4 Functional Architecture: the discrete functional elements of the system and the associated logical interfaces. square4 Physical (Network) Architectur

37、e: the discrete physical (network) elements of the system and the associated physical interfaces. square4 Protocol Architecture: the protocol stacks involved in the operation of the system and the associated peering relationships. availability: measures percentage of time when a location system is a

38、ble to provide the required location-related data. NOTE: The required location-related data might vary between location based applications. It may not only contain a required type of information (e.g. position and speed), but also a required quality of service (e.g. accuracy, protection level, authe

39、ntication). continuity: likelihood that the navigation signal-in-space supports the accuracy and integrity requirements for the duration of the intended operation NOTE: It guarantees that a user can start an operation during a given exposure period without an interruption of this operation, assuming

40、 that the service was available at beginning of the operation. Conversely, 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 tha

41、t a detected but unscheduled navigation interruption after initiation of an operation electromagnetic interference: any source of RF transmission that is within the frequency band used by a communication link, which degrades the performance of this link NOTE: Jamming is a particular case of electrom

42、agnetic interference, where interfering radio signal is deliberately broadcast to disrupt the communication. ETSI ETSI TS 103 246-1 V1.1.1 (2015-04)7 fraud: any kind of activity of a location-based application stakeholder aiming at jeopardizing the application objective. NOTE: By extension, it descr

43、ibes the activity aiming at reporting a falsified location target position in the frame of location-based applications. integrity: function of a location system that measures the trust that can be placed in the accuracy of the location-related data provided by the location system NOTE: In the presen

44、t technical context, it is expressed through the computation of a protection level. The Integrity function includes the ability of the location system to provide timely and valid warnings to users when the system should not be used for the intended operation. Specifically, a location system is requi

45、red to deliver a warning (an alert) of any malfunction (as a result of a set alert limit being exceeded) to users within a given period of time (time-to-alert). Related to the Integrity concept, a Loss of Integrity event occurs when an unsafe condition occurs without annunciation for a time longer t

46、han the time-to-alert limit. integrity risk: probability that the actual error of the location-related data is larger than the protection level, in case of system availability (i.e. protection level lower than the alert limit) jamming: deliberate transmission of interference in order to disrupt comm

47、unications NOTE: In the present technical context, targeted communication signals are GNSS or telecommunication signals. latency: latency of a location system measures the time elapsed between the event triggering the determination of the location-related data for (a) location target(s) (i.e. locati

48、on request from external client, external or internal event triggering location reporting), and the availability of the location-related data at the user interface location-based application: application that is able to deliver a location-based service to one or several users location-based service:

49、 service built on the processing of the Location-related data associated with one or several location targets location-related data: set of data associated with a given location target, containing one or several of the following time-tagged information elements: target position, target motion indicators (velocity and acceleration), and Quality of service indicators (estimates of the position accuracy, reliability or authenticity) NOTE: It is the main output of a Location system. location system: system responsible for providing to a location based
