NMEA Gps!

NMEA client and server. Read GPS Data from core location ( or through direct connection for supported GPS, currently DUAL XGPS150 / 160 are supported ) and forward to other apps/devices through NMEA protocol ( supported by many apps ); an internal NMEA client automatically connects to NMEA Server if active ( or it can be used to test and display data from other NMEA sources, disabling internal server and configurating it )NMEA Fps supports both TCP and UDP clients ( configurable ) . Follow this tutorial to connect QGIS to your iPhone GPS ( other GIS applications have similar features, please let me know if you successfully connect to other GIS applications, or directly comment the tutorial ):http://www.3bsoft.com/it/menuprincipale/news/3-news/49-qgisnmeagps.htmlSatellite data are not reliable when app connects to GPS through core location, that does not forward these kind of info; in any case, app can perform direct connection to DUAL XGPS 150 e XGPS 160 from dual electronics ( if available ), and get complete gps data (satellite info included) at a frequency up to 10 hz .The dual gps is available here :http://www.amazon.com/gp/product/B00E65TNYE/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B00E65TNYE&linkCode=as2&tag=b3softcom-20&linkId=KL3ERE5LYWDFKS5HYou can activate LOG and export generated file to give a look to NMEA data and detect problemsContinued use of GPS running in background can dramatically decrease battery life.
