GlobalSat Waterproof Serial GPS Receiver BR-355-S4

The BR-355-S4 GPS Receiver can be utilized in a variety of applications which require GPS signals to be received and decoded in your Windows laptop or tablet PC, and for Mac users, their Mac Books or Mac Book Pro's. Compatible with most all NMEA compliant third-party software, the BR-355-S4 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 BR-355-S4’s slim profile housing has a IPX7 water resistant rating, and incorporates an active patch antenna for the highest level of GPS accuracy. The BR-355-S4 requires either the USB, or Serial RS232/PS2 cable sets to function (sold seperately) via USB. Placement of the GPS receiver anywhere within the vehicle will usually get sufficient GPS signal reception, but in those rare occurrences when towering high-rises offer challenging satellite reception, simply place the BR-355-S4 on the vehicle’s roof (attaches with its built-in magnet) for improved reception. Since power is transferred through your PC's USB port or the keyboard port, depending on which cable set is connected. Data is also transmitted to the USB port or the RS232 port depending on which cable set is used.

The BR-355-S4 uses a propriatary pin-out on the PS2, which cannot be connected directly to any laptop or PC without the use of a cable set (USB or RS232 + PS2 for power)

The BR-355-S4 can be used to feed GPS output into Moving Map Software such as OziExplorer CE to display your location on digital topographic maps (such as those supplied by Spectrum Digital Imaging) or marine cartography (Digital Ocean products) your own scanned maps, or even on aerial photos or NASA Satellite Images! (OziExplorer Development Version and CE addon required.)
