NMEA Gps vs Sailing Master M

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.

Sailing Master M offers comprehensive sailing data and performance optimization information on iPhones, iPads, iWatches, and ActiveLook smart glasses. The application provides configurable pages and data displays, utilizing over 35 sailing measurements from the boat’s instruments, polars tables, and nautical charts. On phones and pads, the Data and Analog Displays can include minimum and maximum values and time series graphs. The Wind Display provides wind, heading, route, and speed information. The Route Display shows the expected wind conditions on the next legs. The Map Display shows the vessel with direction, tacking and downwind laylines on a nautical chart, or the wind laylines in another location. The connectivity is through NMEA 0813 Wi-Fi gateways such as B&G Vulcan, Zeus, GoFree, Yacht Devices, Signal K, Actisense, and ShipModul. The application has evolved from its initial focus on NMEA data display to encompass a comprehensive suite of features. Consequently, the app’s name has been revised from 'Display0183M' to 'Sailing Master M'. For further information, please refer to the user’s guide available on the app’s website or within the app itself.
