The diagram in the center shows the approximate positions of satellites relative to your location
that are within range of the receiver. The graph at the bottom of the page shows the signal
strength of each satellite. A green bar indicates acceptable signal strength; a blue bar indicates
marginal reception. You must have at least four satellites with acceptable signal strength to
generate reliable position data.

Assisted GPS (AGPS) is an option that uses your wireless network connection to quickly
download the GPS almanac and ephemeris information your system needs to compute a first fix
on your location. This greatly reduces the time to first fix (TTFF).
With AGPS, your system can acquire an accurate fix in less than 30 seconds. Without AGPS,
the TTFF can take as long as 15 minutes depending on surrounding structures and the strength
of the satellite signals.
