Mhz), integrated SiRFstar III GPS with patch antenna and 5 watts of RF
power output. All on a single board measuring less than 1 1/4 x 3 3/4
The high sensitivity 20 channel WAAS capable SiRFstar III GPS allows
operation in areas where GPS reception is troublesome, including
"urban canyons", wooded areas, even inside buildings.
Nonvolatile on-board memory stores more than 1000 waypoints at a user
selectable rate which can be downloaded as a .kml file viewable via
An integrated voltage regulator allows direct connection to an
automobile (or any unregulated 12V) power source For truly portable
operation, you may also provide power (4-9 volts) via (2)
lithium-poly (7.4v) or (6) alkaline batteries (9.6v).
The transmitter supports fixed beacon rates, time slotting and
SmartBeaconing (TM) for dynamic transmission rates based on speed and
