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

Location-Based Service (LBS)

By • • Knowledge, Project, Public, Research, Teaching • , , • 2 minutes of reading

A Location-Based Service (LBS) is usually a service running on a mobile device that provides facts or recreational information. It employs geolocation to make the facts or entertainment more personal to the user of the application. An example of a typical LBS is one that identifies the location of a device and then discovers the location of restaurants in the immediate vicinity of that location. As LBS become more common, their commercial value will become more readily evident to corporations, who can use them to personalize users’ experiences with location-aware weather, coupons, and advertising. This is already becoming more common,
