| In the ideal geographical environment, the GNSS location solution provides medium accuracy of 10-100 meters, and various augmentation schemes have been added to improve this. For practical purposes, however, GNSS solution fails to meet the requirements of the mass market because GNSS receivers have poor coverage measured by the percent of time they work where most people spend most of their time. GNSS receivers do not work indoors or under cover. They also work poorly in urban canyons formed by high-rise buildings preventing them from seeing enough satellites.
In comparison, Radiant eNMR positioning technology guarantees consistent positioning performance even under specific circumstances such as indoors and urban canyon with minimum impact on existing mobile handsets & infrastructures. Hybrid operation between eNMR positioning technology and A-GNSS, therefore, is one of the most feasible location solutions to meet the customer's requirements. |
