For GPS, coordinates, status (Fixed, Float, Autonomous) and HRMS and VRMS accuracy estimates are displayed at all
times. The icons at the left are for zooming and panning. From top to bottom, they are: zoom extents, zoom in, zoom
out, zoom window, zoom previous and point display control. If you prefer to work in a pure text screen, without
graphics, you can tap the helmet icon and select TEXT. The following dialog will appear.
The Text screen uses a large character size for easy viewing, and limits options to Monitor/Skyplot, Offset and Store.
You can return to the graph view by tapping the GRAPH button. You can also temporarily view your points on the
screen by tapping Map, then tap Back to return to the text-based data collection screen. Note that the program will
remember which screen you were in last (Graph or Text) and return to that mode of data collection automatically.
In addition to pressing Enter, Points can be Stored by selecting this icon (ALT-S).
Average
With GPS, since shots tend to cluster around the true point location, it may add to accuracy to Average 10 or more GPS
readings when taking measurements. You will be prompted for how many readings to take (up to 999). Taking 100
readings is also a way to gauge how fast your GPS equipment takes measurements. If 100 readings are taken in 10
seconds, you are reading at 10 per second, or 10 hertz (hz). After the readings are taken, a display appears showing the
range and standard deviation of the readings.
