Sub-Meter Accuracy in Consumer Smartphones: Advancements and Challenges in GNSS Positioning

By • • Knowledge, Research, Teaching • , , , , , , , • 3 minutes of reading

By Shahabuddin Amerudin Sub-meter accuracy in the context of GNSS (Global Navigation Satellite System) refers to the capability of a receiver to determine its position with an accuracy of less than one meter, typically in the range of centimeters or decimeters. This level of accuracy is highly desirable for various applications, including augmented reality, precise navigation, surveying, agriculture, and other location-based services where high precision is crucial. To achieve sub-meter accuracy, GNSS receivers need access to highly accurate and precise satellite positioning data. Traditional consumer-grade GNSS receivers, such as those found in smartphones, typically provide accuracy in the range of
