Internet of Things
IoT is to achieve automatic working mode without the participation of people based on sensors, communication, positioning and other technologies between devices, in combination with AI and big data for analysis and processing. Thus, IoT can effectively improve the efficiency of production management and make life smarter and safer.
Positioning trackers need to be small and light, and GNSS can be queried at any time. When the mobile phone APP sends the query instruction, the communication module will respond quickly after receiving the instruction, enable the positioning immediately, get the positioning information and upload. Check the status of people and pets in real time to prevent loss or accidents.  For smaller positioning chips, fast positioning ephemeris service is the main focus of the positioning tracker.

NB-IOT is an emerging technology in the field of Internet of Things introduced in recent years, which supports low-power devices’ cellular data connection in WAN. It has a long standby time and supports a large number of connections. It can work for a long time only depending on the battery. GNSS as a position sensor, when combined with NBIOT can effectively enable the background to automatically get the device location, reducing the workload for calibration and locating the device. It is widely used in asset tracking, smart cities, bicycle sharing and other fields.   As a standardized product, module is applied in many fields. Its size is strictly limited, requiring GNSS chips to be minimized as possible. High performance and high reliability are also key to dealing with complex environments.

Intelligent wearable device based on the application of wearable technology for intelligent design of daily wear, mainly including all kinds of watches, bracelets and so on. It is mostly used for outdoor sports, fitness and human health monitoring. Besides recording the movement trajectory, GNSS can also accurately upload location information in the first time in the event of accident or physical discomfort, providing guidance for the following rescue.   The popular smart wearable devices on the market are compact and sophisticated with a long-endurance, which requires GNSS chips to be small in size and extremely low in power consumption. Intelligent wearable devices with positioning capabilities have certain requirements for positioning accuracy, which requires the sensitivity of the built-in GNSS chip.

Location information and communication technologies are the core of IoT devices, and each device is a sense unit. The system contacts other needed sense units to collect analytical data and give feedback based on the changes in the location of the sense unit. On the other hand, the combination of GNSS and communications is easy for industry customers to use, improve reliability, reduce development cycles. The complex diversity of the environment in which IoT devices are located, the randomness of placement, the miniaturization of the device itself and the long standby time also pose new challenges to the GNSS chip.

Unicorecomm 28nm UC6226 chip with a smart PMU design, featuring ultra-low power consumption and extreme miniaturization, significantly improves the cruising ability of the device. UC6226 has a built-in SensorHub, which can access multiple sensors for integrated positioning. Through accurate scene and context recognition, it can ensure a faster and more accurate positioning even in harsh signal environments. UC6226 is oriented to global applications, supporting BDS, GPS, GLONASS, Galileo, and can carry out positioning jointly with other systems.
