The BU-353 GPS Receiver can be utilized in a variety of applications which require GPS signals to be received in your Windows laptop or tablet PC, and for Mac users, their iBooks or Powerbooks. Compatible with most all NMEA compliant third-party software.

· The BU-353 is suitable for use in vehicle, marine and aviation navigation, as well as commercial and municipality applications such as fire trucks, police cars, buses, GIS data collection and much more!

· The BU-353’s slim profile housing is completely water resistant and incorporates an active patch antenna for the highest level of GPS accuracy. With a 60” cable, placement of the GPS receiver anywhere within the vehicle will usually get sufficient GPS signal reception.

The BU-353 is no need for batteries or any other external power source, since power and data are transferred through the same USB cable from the BU-353.
