6. AssistNow configuration with u-center 8.xx 
 

The NL-8009T supports AssistNow. 
AssistNow is a standard A-GNSS service, which increases the performance of the GNSS 
receiver, by calculating a position almost immediately, even under difficult reception conditions. 
A-GNSS improves all GNSS capable applications, especially those that require a continuous 
state of readiness, for example applications for fleet management or GNSS capable hand-held 
devices, whose users would like to access local services immediately, independently of the 
reception conditions. 

 

Without A-GNSS, a GNSS receiver must localize at least 4 satellites in direct line of vision, and 
then download their location data. This process takes 26 seconds under optimal reception 
conditions, but under less favorable conditions it may take much longer, e.g. in an urban 
environment or in a building, where the GNSS reception is weaker. AssistNow sends the data 
directly to the GNSS receiver, thus enabling a quick calculation of the position. 

 

The offline service provides support data, which are valid up to 14 days. The user can thus profit 
for longer periods from the increased satellite acquisition performance, and they need an internet 
connection only occasionally, in order to update the support data. 
The call-up and data transmission functions can be found in the menu bar of the u-center. 
Click on the A-GNSS function in the menu bar to update AssistNow and to load the NL-8009T.
