With the advent of automated driving systems in the automotive sector, the demand for GNSS navigation systems is increasing significantly. A variety of GNSS receivers, also known as satellite navigation (Sat Nav) systems, are used in vehicles for private and recreational purposes, as well as in commercial and public transport. Also, electric cars require precise knowledge of its velocity and slip angle to achieve maximum performance in terms of acceleration, handling, and agility in every situation, the GNSS module helps in extracting this information. Moreover, the GPS-enabled communications control unit enables drivers to capture ride data and download them into their smartphones and tablet applications over Wi-Fi. This helps the rider to analyze the ride data directly on the GPS trajectory, which increases the demand for GNSS. In vehicles, the GNSS chips help in reducing the power consumption and expenses, also known as the bill of materials (BOM) costs, associated with in-vehicle navigation systems. The navigation chips comprise input settings and sensors for accelerometers, gyroscopes, and magnetometers which offers a fused sensor data tracking subsystem and helps in recording the position of cars in urban environments and blocked areas.
Although most vehicle telematics already provides communication services with basic positioning requirements, the GNSS chipset manufacturers and value-added service providers are planning to acquire new satellites and frequencies to improve the positioning performances which is further expected to fuel the growth for GNSS market in the coming years. Moreover, the integration of GNSS with inertial navigation system (INS) in automotive navigation systems is increasing widely due to operational performance issues caused by GNSS system and receiver errors. For instance, GNSS connectivity chip by Broadcom, a designer, developer and global supplier of semiconductor products, helps automotive manufacturers and tier 1 suppliers to achieve advanced precision and reduce power consumption, while also lowering BOM cost. Furthermore, automobile manufacturers in countries such as Japan, the US, Germany, Korea, and China are researching and developing their automated driving system by collaborating with industries, academia, and governments.
