EXPLORING MARKET STREET WITH THE ANELLO GNSS INS

Market Street in San Francisco is one of the major routes across the city, with a diverse urban landscape. It poses numerous challenges in navigating autonomous vehicles effectively due to narrow streets with skyscrapers, resulting in limited sky view and severe multipath.
In this case study, we explain how we tested the ANELLO GNSS INS along Market Street in San Francisco and evaluated its performance in real-world driving conditions compared to other established Inertial Navigation Systems solutions in the market.

BACKGROUND

Market Street, a 3.5-mile urban artery in San Francisco, winds through diverse neighborhoods and commercial zones, presenting a formidable challenge for vehicle navigation due to its bustling traffic and towering urban canyons.
The ANELLO GNSS INS offers a cutting-edge solution to this complex environment, seamlessly integrating data from its Optical Gyroscope with GPS signals and wheel speed odometry. This advanced system ensures precise navigation even in GPS-challenged areas, making it particularly well-suited for the demanding conditions of Market Street's urban landscape.

TEST DRIVE RESULTS IN URBAN ENVIRONMENT

To evaluate the ANELLO GNSS INS Inertial Navigation System's performance, we outfitted a test vehicle with the ANELLO GNSS INS and another well-established, comparable system. We then conducted multiple drives along Market Street, focusing our assessment on the system's overall heading and positional accuracy. This real-world testing allowed us to gauge the capabilities of the ANELLO GNSS INS in a challenging urban environment known for its GPS signal interference due to restricted sky visibility and significant multipath interference.
Overall, the test of the ANELLO GNSS INS on Market Street revealed impressive performance. The system exhibited exceptional positional accuracy throughout the challenging urban canyon environment. The ANELLO GNSS INS maintained a remarkably close alignment with the vehicle's actual position along the entire route. Notably, the ANELLO GNSS INS demonstrated a drift of approximately 1 meter on multiple occasions, significantly outperforming its competitor’s drift rates of 15.5 meters, over a drive length of 250 meters (see Fig. 2).

CONCLUSION

The ANELLO GNSS INS’s successful trial on San Francisco's Market Street demonstrates its exceptional performance in real-world urban conditions. Leveraging ANELLO's innovative optical gyroscope technology, the system delivered precise positioning and reliable navigation despite the challenging environment of bustling traffic and intricate city layouts. This impressive showing underscore the ANELLO GNSS INS’s potential to transform navigation in complex downtown settings.
The demonstrated reliability and precision of the ANELLO GNSS INS in challenging urban settings, particularly when measured against more costly and established market competitors, underscore its exceptional value for diverse autonomous applications. Through its consistent delivery of dependable performance, the ANELLO GNSS INS establishes itself as a key facilitator for successfully implementing autonomy in complex metropolitan environments. This advanced system's ability to maintain sub-meter accuracy in GNSS-loss scenarios makes the ANELLO GNSS INS uniquely suited for navigating in challenging urban environments.
The ANELLO GNSS INS achieves exceptional performance through its advanced sensor fusion algorithms and proprietary optical gyro technology. This powerful combination enables accurate detection of GPS-challenged environments and high-precision dead reckoning in areas with poor GPS coverage. By providing more reliable navigation in GPS-denied conditions, the ANELLO GNSS INS enhances safety in autonomous vehicle applications and reduces dependence on other sensors like lidars and cameras, which may have limitations in certain scenarios. This robust performance demonstrates how a more accurate INS can significantly improve the overall reliability of an autonomous vehicle's sensor suite.
