The Space_E800_1X_3G NMEA Device appears to refer to a GPS receiver or navigation device that uses the NMEA (National Marine Electronics Association) protocol to communicate with other devices, such as computers. The NMEA protocol is a standard used for transmitting data from GPS receivers to other devices, which could include navigation systems, software, or even custom applications that require GPS data for positioning, tracking, or mapping.
In this case, the Space_E800_1X_3G is likely a model of GPS hardware (possibly from a brand called Space, or a third-party brand that uses this name) designed to work with mobile or desktop systems, providing GPS data that can be used by mapping software, tracking applications, or other systems requiring precise location data.
