Another purpose of the present utility model is, proposes a kind of global position system receiving trap.Can make the navigation software that has existed on the market at present, all can reach by design originally the NMEA value of correct height and orientation angle comparatively, and can remove to judge the orientation angle and the place height of present location, correctly be presented on the map, and can make correct path planning effectively and inform path that the consumer is correct and real-time planning.

For achieving the above object, the utility model provides the global position system receiving trap of a kind of tool height and correction for direction, comprising: at least one satnav Anneta module, and it can receive a satnav radio wave signal and export a digital signal; One satnav processor, it connects this satnav antenna to receive and to handle this digital signal, exports at least one data set at last, and this data set comprises the locating information of an American National ocean Institution of Electronics agreement at least; One direction sensor, it detects the moving direction of this global position system receiving trap; One altitude gauge, it detects the Level Change of this global position system receiving trap; And a microprocessor, it connects this satnav processor, this direction sensor, this altitude gauge, and this moving direction and this Level Change are inserted this locating information and exported this locating information to a NAVSTAR.

The utlity model has following useful technique effect:

1, the utility model can be with orientation angle and the height value in American National ocean Institution of Electronics (NMEA) value of script GPS output, cooperation via microprocessor, patrol resultant height of dish and deflection value with highly taking into account electronics, treated correction obtains correct NMEA value later and exports system to.

2, the utility model can make the navigation software that has existed on the market at present, all can reach by design originally the NMEA value of correct height and orientation angle comparatively, and can remove to judge the orientation angle and the place height of present location, correctly be presented on the map, and can make correct path planning effectively and inform path that the consumer is correct and real-time planning.
