GPS vs Nautical Rules

This application uses the GPS for presenting speed, course, altitude and the location coordinates. The magnetic sensor presents the compass heading. You may send sms with your latitude and longitude direct from the app to any number or to a saved number. You can also show the map and from there share your position in different ways, as messages, mail or in social media. For devices with barometric sensor it presents pressure in hPa, and also the relative pressure change, after the app is started, very accurate, in meter or feet. As long as the geo data senses street address it will be continuously presented.
