29、sent document is part 3 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
30、 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“
31、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 et
32、c., 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 app
33、lications. 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.
