Compatible with most all third-party software compatible with NMEA, the BR-355-S4 is suitable for use in vehicles, maritime navigation and aviation, as well as commercial applications and municipal such as fire trucks, police cars, buses, collection of data, GIS, and much more! The housing of the slim profile of the BR-355-S4 has a water resistance classification IPX7, and incorporates a patch antenna is active for the highest level of GPS accuracy. The BR-355-S4 requires that the sets of cables USB or Serial RS232 / PS2 to operate (sold separately) via USB.
The placement of the GPS receiver anywhere within the vehicle will usually get sufficient reception of GPS signal, but in those rare cases when the tall skyscrapers offer a satellite reception poor, simply place the BR-355-S4 on the vehicle's roof (attaches with its built-in magnet) for improved reception. Given that the energy is transferred through the USB port of your PC or the keyboard port, depending on the set of wires that is connected. The data are also transmitted to the USB port or the RS232 port according to the set of cables that you use.
