| Hybrid Operation with GNSS |

| |
| Expanding the Boundaries of GNSS Location Solution |
| |
| In ideal geographical environment, the GNSS location solution provides
median accuracy of 10 meters, and various augmentation schemes have
been added to improve this. For practical purposes, however, GNSS
solution fails to meet the requirements of 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 canyon
formed by high-rise buildings prevent them from seeing enough satellites. |
| |
 |
| |
| In comparison, Radiant positioning products guarantee consistent
positioning performance even under specific circumstances such as
indoors and urban canyon with minimum impact on existing mobile terminals
& infrastructures. Hybrid operation between Radiant products and
A-GNSS, therefore, is one of the most feasible location solutions
to meet the customer requirements ; |
|
 |
| |
- Maximizes LBS availability with accuracy that meets FCC E911
Mandate
|
| |
- Minimizes cost for actual deployment and maintenance
|
| |
- Standard-based approach (OMA SUPL)
|
| |
|
 |
| |
| In addition, Radiant positioning
products enable Advanced Hybrid Operation through proprietary algorithms
in an uncertainty estimation. In cases where an uncertainty value
for eNMR meets QoP, Advanced hybrid operation actually reduces the
working of GNSS receiver at the mobile terminal and it has some advantages
as follows ; |
|
|
| |
- Eliminates latencies for the fastest response of LBS applications
|
| |
- Extends the battery life of A-GNSS mobile terminals
