Experience Sharing: How to choose the right indoor positioning solution

Outdoors, it is known that the starting point and the destination point can complete the route planning and navigation service through the position information fed back by the GNSS positioning module of the mobile terminal and the vehicle terminal. Indoor positioning, as an extension of outdoor positioning technology, has made up for the deficiencies of traditional positioning technology. It has also been widely used in indoor navigation, mobile payment, in-store shopping guide, flow analysis, item tracking, etc. In order to facilitate the application of indoor positioning and navigation, how should an engineer choose a suitable indoor positioning solution?

Indoor Positioning

The commonly used positioning solutions for indoor positioning are technically divided into WiFi positioning technology, inertial navigation technology, Bluetooth technology, RFID technology, infrared technology, ultrasonic technology, ultra-wideband technology, and LED visible light technology. There are numerous indoor positioning technologies. Each technology has its own limitations and there is competition between them to some extent. As a user, it is definitely more inclined to choose an indoor positioning solution that satisfies the positioning accuracy while the overall solution is less difficult to implement and costs more controllable.

Comparison of indoor positioning solutions

At present, SKYLAB can provide customers with indoor positioning solutions based on Bluetooth technology Bluetooth beacon program, Bluetooth gateway program and ultra-wideband UWB technology centimeter-level high-precision indoor positioning program. How to choose a suitable indoor positioning program? Here, Xiao Bian has come to share two points. I hope that the indoor positioning engineers can quickly grasp the selection skills of indoor positioning solutions.

From the positioning accuracy: From the indoor positioning program comparison chart, we can clearly see the positioning accuracy of each positioning program is different, if you actually use, you need to achieve centimeter-level positioning accuracy, obviously, ultra-wideband UWB Indoor positioning solutions can better meet the needs; if the actual application, positioning accuracy as long as the meter can be, you can choose Bluetooth indoor positioning program.

Bluetooth indoor positioning solution

From the perspective of practical applications: Taking the Bluetooth indoor positioning solution as an example, the Bluetooth-based indoor positioning solution can be divided into a Bluetooth beacon scheme and a Bluetooth gateway scheme. How to choose? It is very simple, in your actual application is to realize the positioning function, or the navigation function. In the previous introduction of the Bluetooth indoor positioning solution, SKYLAB Jun introduced the difference between the two in great detail: The Bluetooth Beaconing Solution (VG01/VG02) is also a terminal-side positioning solution that we often refer to. We need to rely on a mobile phone to know the location. , It is an active positioning that can achieve navigation services within the indoor environment; Bluetooth gateway program (TD03/TD05/TD05A) is also what we often say network determination bit program, designed to let others know where they are, is a passive positioning, in To a large extent, it can meet the positioning needs of indoor assets.

SKYLAB's terminal-side positioning can be applied to indoor terminals, navigation, marketing route planning, reverse car search, precise location marketing, and other user terminals. The network-side positioning can be used in people tracking and positioning, smart attendance, access control systems, asset location and passenger flow analysis scenarios. At present, Tiangong's indoor positioning solutions for measurement and control are mainly based on customized development. After all, customer application requirements in different industrial fields are different. If you are just interested in SKYLAB's indoor positioning solution, you can consult SKYLAB website or Ali store.
