7. AssistNow configuration with u-center 8.xx
The NL-8006U 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-8006U.
