The BR-355
GPS Receiver can be utilized in a variety of applications that require
a magnetic mounting with waterproof configuration. With non-slip on
the bottom and the special compact design, the BR-355 is completely
self-contained and waterproof. It incorporates the latest SiRF Star
III GPS chipset and an active patch antenna so you receive a high
degree of GPS accuracy.
Typical application can include marine environments, aviation, commercial
use such as fire truck, police cars and utility vehicles and buses.
The extended 5 feet long cable allows for easy routing to your PDA
behind headliners and side panels and terminates to a custom PS/2
connector for interfacing with one of the available cable kits.
