NavStation is a utility to aid boat navigators. It uses the iPhone 3G's in-built GPS to fix a position and then displays this in three common formats - Decimal Degrees (d), Degrees + Decimal Minutes (D m) and Degrees + Minutes + Decimal Seconds (D M s). This allows for very simple plotting of positions on paper charts. NavStation's night mode means that the navigator can preserve their night vision when plotting a fix on the chart.
Nav Station also shows Course-Over-Ground (COG) in °(T), Speed-Over-Ground in kts as well as providing the time stamp of the latest fix. This can be used to sanity check the fix data on the paper chart very quickly.
GPS status is provided if off, acquiring a fix or fix accuracy strays outside 50 meters.
NavStation offers both a day mode and a night mode for navigators wishing to preserve their night vision. Modes are switched by swiping the screen horizontally.
You can set the startup state of NavStation as either day or night and with GPS on or off. You can also specify an automatic 'GPS Off' timer.
Battery life of the iPhone is also maximized by providing a configurable auto shutdown of the GPS hardware between fixes.
GPS hardware can also be manually toggled on and off by swiping vertically.
