Abstract

The present application discloses a receiver system for positioning, a method for arranging the receiver system, and a positioning system comprising the receiver system. The receiver system may comprise a group of nodes, the group of nodes comprising receive nodes for receiving a ranging signal. In this group of nodes, the receive nodes may be arranged according to a predetermined mode. Further, the group of nodes may comprise a reference node, and locations of other receive nodes within this group of nodes may be determined based on information on the predetermined mode and location of the reference node. With the present invention, the receiver system may have a more flexible structure, which may be better adapted to complex situations in practical application. At the same time, the calibration workload in a complex application situation can be significantly reduced.

Description

technical field [0001] The present invention relates to positioning technology, and more particularly to a receiver system for positioning, a method for arranging the receiver system and a positioning system comprising the receiver system. Background technique [0002] In a ubiquitous computing environment, a location tracking system (LTS) is required to provide location services in order to enhance existing applications and support new applications. Currently, there is an increasing demand for highly accurate tracking of people and objects in many applications such as warehouses, mines, subways, smart buildings, healthcare, and restaurants. [0003] For example, in a warehouse, real-time tracking of the exact location of goods is required for efficient management of goods. Typical examples can include tracking of steel goods in steel mills, commodity tracking in retail warehouses, etc. Especially for goods that are sensitive or even dangerous to people, it is more necessa...
