7. AssistNow configuration with u-center 8.24
The NL-82004U 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, enabling a quick
calculation of the position.
The offline service provides support data, which are valid up to 35 days. The user can 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.
