7. Assist GPS configuration with u-center 7.xx
The NL-6002U supports AssistNow.
AssistNow is a standard A-GPS service, which increases the performance of the GPS receiver,
by calculating a position almost immediately, even under difficult reception conditions. A-GPS
improves all GPS capable applications, especially those that require a continuous state of
readiness, for example applications for fleet management or GPS capable hand-held devices,
whose users would like to access local services immediately, independently of the reception
conditions.
Without A-GPS, a GPS receiver must localize at least 4 satellites in direct line of vision, and then
download their location data. This process takes 30 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 GPS reception is weaker. AssistNow sends the data directly to the GPS
receiver, thus enabling a quick calculation of the position. AssistNow sends the data directly to
the GPS 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 AGPS function in the menu bar to update AssistNow and to load the NL-6002U.
