NAVIGATION SATELLITE SYSTEM Market

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. Thus, the shipment rate of GNSS chips is increasing with their growing utilization in automotive infotainment systems and in-vehicle systems, thereby contributing to the growth of the market

Unmanned aerial vehicles (UAVs) are radio-controlled aircraft that are equipped with sensors, target designators, or electronic transmitters for surveillance and other observatory applications without any manual assistance. The technology was previously used in military and defense and government verticals as it offers a longer time of flight and greater surveillance range when compared to manned systems. Technological advancements have encouraged the software developers to integrate UAVs with collaborative technologies such as the Internet of Things (IoT), artificial intelligence (AI), 3D modeling, and augmented and virtual reality (AR/VR). UAVs rely upon GNSS for the provision of reliable position coordinates. The technology offers UAVs with continuous mobile positioning and high accuracy orientation for applications such as navigation, guidance and control of unmanned vehicles as well as mapping and survey from UAVs. Integrating position technologies such as GNSS and inertial technologies with wireless communication to the UAVs allows the customers to achieve product differentiation and gain a competitive edge in the marketplace thereby offering market growth opportunities in the coming years.

GNSS-enabled devices are used for long-time monitoring applications and hence are susceptible to rapid power loss. These devices must communicate with the transceivers for position updates as well as maintain their accuracy. However, frequent updates from these devices might result in considerable power consumption. Thus, it becomes difficult for GNSS device manufacturers to build power-efficient modules for positioning devices. In addition to this, the increased adoption of GNSS chips in smart wearables for positioning and activity tracking has resulted in the reduction of battery size, which impacts the efficiency of GNSS chips and increases the power consumed by them. Moreover, when the GNSS devices are used for marine applications, they are likely to be interfered by other electromagnetic signals. These factors result in intensified power consumption by GNSS enabled devices which can limit their adoption and affect the market growth

GNSS has marked its presence in various applications ranging from smartphones and vehicles to surveying and referencing applications. However, when the GNSS enabled antennas are placed in a confined environment, they tend to lose accuracy as well as the quality of positioning in such restricted environments. In urban areas, the GNSS signals are blocked by buildings, resulting in poor cross-street positioning and deprived geometry for localization. Therefore, it becomes challenging for device manufacturers to provide real-time locations for major mobile applications including navigation, geo-fencing, mobile coupons, and ridesharing. GNSS open signals are susceptible to electromagnetic interferences accompanied with low power, low chip rate, and short period of PN codes at ground level which might result in jamming and spoofing of signals. Hence, the concerns regarding the precise navigation of objects present in indoor, underground, and underwater environments possess a major challenge for GNSS device manufacturers.
