ellites. The Motorola GPS receiver provides accurate informa-
tion after synchronizing with at least 3 of the 24 satellites.
The Yellowjacket Plus must have a clear view of a good por-
tion of the sky in order to communicate with the GPS satel-
lites. The GPS receiver should lock within a few minutes. The
only exception is when the unit is turned on in a new area. If
the receiver was last turned on in California and now in New
Jersey, the GPS receiver could take up to an hour to lock.

RTC MARKER MODE
If there is no GPS module attached, the YellowJacket system
uses the internal real-time clock of the iPAQ for timing. In
addition, there is a marker that starts at 0. By pressing the but-
ton to the right of the marker value, the marker increases by 1.
These values are stored in any log files created for later con-
version by Chameleon. The screen above shows Yellowjacket
with an internal GPS receiver detected. The screen below
shows the RTC window when no GPS receiver is detected.
