NMEA Gps vs GRTech Beacon 4.0/5.0 NTRIP

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 ) . Note that UDP , for protocol limits, will work only when iPhone is connected to a wifi router Current gps position cab be shown as qrcode, enlarged and shared This app allows reading GPS info from devices that lack of an internal GPS ( such as iPod and iPad wifi ), and from your desktop pc, simply connecting to the device running NMEA Gps app; you can share the *same* gps info (possibly derived from an external GPS) among multiple devices ( even if they lack of an internal GPS); useful for regatta app , all members will get same info. 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.html Satellite 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=KL3ERE5LYWDFKS5H You can activate LOG and export generated file to give a look to NMEA data and detect problems Continued use of GPS running in background can dramatically decrease battery life.

GRTech Beacon 4.0/5.0 NTRIP Client is designed to deliver RTK corrections to GPS receivers capable of receiving them. This app is intended to be used exclusively with the GRTech Beacon 4.0/5.0 family of devices. Continued use of GPS running in the background can dramatically decrease battery life. Background GPS usage will end when you stop the data stream or the Beacon is no longer connected.
