GNSS (Global Navigation Satellites System) is a world-level fusion project, to offer high-precision solutions worldwide. By capturing satellites from different constellations such as GPS (from USA), GLONASS (from Russia), Beidou (from China), GALILEO (from Europe), QZSS (from Japan), NavIC (from India) and other SBAS, L-band, etc services, nowadays GNSS can deliver a highly accurate and stable positioning everywhere.

Our daily needs, ranging from smartphone positioning, vehicle navigation, and smartwatches to emerging drone mapping and drone solution seeding, etc, are exemplary manifestations of accurate positioning. GNSS technology has brought a lot of convenience to our lives, for example, autonomous driving development and CORS covering every country, and this positive impact will be reflected in more aspects.

Taking the current autonomous driving system as an example, equipped with ComNav’s K803 GNSS Module (GNSS+INS supported), it enables to the provision of higher reliability and higher integrity positioning information. The positioning data can output under most of the challenging conditions in rainy, snowy, or foggy environments, to reach lane-level navigation. Thanks to the higher accuracy positioning, map matching can be performed in a smaller range meanwhile the required computing power is reduced. Working with other sensors, GNSS technology provides a strong backup for the safety of autonomous driving. The other significant result is map cost is slowed down to a large extent.

GNSS+INS navigation GNSS navigation only

Compared with the GNSS-only positioning system, the GNSS+INS system can significantly enhance navigation performance, wherever in the urban canyon, near buildings, under heavy tree cover, or even in a tunnel.

GNSS technology ensures accurate, stable, and reliable positioning navigation results, to help vehicles get their real location. With its fusion with other sensors like LiDAR, bomb-wave radar, cameras, etc, vehicles get more accurate positioning and heading and an overall and accurate understanding of the current environment to facilitate the vehicle making the next decision.

Ushering in the area of a connected future, GNSS and high-precision positioning services will definitely play a key role and be the cornerstone to building up the future world. It is clear to see that more and more functions of the vehicles depend on high-accuracy location. GNSS, initially, helped us find the fastest route to a destination. Finally, we do believe it will help us drive autonomously.
