5G positioning came with multiple new positioning requirements and applications, such as smart factories, autonomous vessels and vehicles, traffic management.
5G positioning technologies has been added to 3GPP Release 16 finalized in mid 2020. They combined a variety of methods to obtain accurate location fixes. These technologies can be classified into two categories according to the physical measurements:
· Range-based measurement is mainly based on the time of arrival (TOA), time difference of arrival (TDOA), or the angle of arrival (AOA) or the frequency difference of arrival (FDOA), to obtain the position.
· Range-free measurement uses multiple sensor technologies to build a feature fingerprint library of locations. These locations enable positioning system to get ideal performance in complex multipath environments.
IPLOOK 5G positioning system provides high-accuracy estimation, with regards to time and angle-based positioning methods.
Its functions:
· Determine the location of terminals by interacting with multiple base stations via NRPPa protocol.
· Support MO-LR, MT-LR, and the event-triggered, and periodical positioning process
· Support positioning techniques defined by 3GPP R16 uplink time difference of arrival (UL-TDOA), Uplink angle-of- arrival (UL-AOA), etc.
