Precision GPS Pro
By sciencewithandroid
'Precision GPS Pro' makes use of your system's GPS sensor to measure your location extra precisely than is possible with typical GPS apps. Turn your phone or pill into a precision GPS navigation instrument.
Normally, software in your Android gadget determines your location from particular person GPS readings. This is fine if your are excited about getting your location to within about 10 meters. However, it's attainable to do better than this if you average many readings at a specific location.
This app is designed to do just that -- average many readings of a stationary Android system to get a more accurate location; it actually calculates a weighted average, accounting for the accuracy of every studying. The trade-off is time. You will want to wait a least a few minutes to get a excessive accuracy average location.
'Precision GPS Pro' shows the next info on the primary display screen:
-'start/stop' button,
-'reset' button,
-'save' button,
-'e-mail' button,
-'UTM' button,
-remaining battery power readout (%),
-current latitude, longitude and (corrected - see below) elevation,
-round number,
-elapsed time,
-PDOP, HDOP, VDOP values,
-number of GPS satellites in view,
-number of GPS satellites employed in fixing location,
-signal-to-noise ratio of signal from every satellite tv for pc,
-accuracy of the current readings,
-weighted average (mean) latitude, longitude and (corrected - see below) elevation,
-graph of the current latitude and longitude (white connected points), the common value (red dot) and a scale box (green),
-'status' of app - either 'Idle', 'ready, 'searching', or 'working',
-sky plot of energetic satellite tv for pc positions,
-option to choose format of displayed coordinates,
-'maps' button to ship average coordinates to a mapping app, corresponding to 'Google Maps.'
The 'reset' and 'save' buttons are inactive whereas readings are being taken. They can be utilized after the 'stop' button is pressed. If the measurements are stopped and then began again without urgent the 'reset' button, then solely the 'elapsed time' value is reset.
The latitude and longitude values are proven on the graph. North is up and east is to the proper, as on a map. The graph automatically rescales to include the extreme values of longitude and latitude each time it updates the graph (every 4 seconds in fastest knowledge acquisition mode).
The green 'scale field' is 2 meters on a side. It will not all the time have a square form, because the graph scaling for latitude just isn't essentially the identical because the graph scaling for longitude. During the early rounds, sometimes only a portion of the scale box is seen; this occurs when the displayed ranges of latitude and longitude are very small.
The elevation is corrected to the EGM96 geoid. This offers absolute accuracy in elevation just under one meter.
A 'settings' screen provides choices to maintain the display constantly on while the app is working, change the interval between measurements (in minutes, with a minimal of 1 minute), choose the language (English, French, Spanish, or German), select the elevation units (meters or feet), choose whether or not to permit the app to run within the background, and select which format to display the coordinates. There can be a button to reset the saved measurements, which could be seen on the 'history' display.
When the 'save' button is pressed, the date, time, and common coordinates are also copied to the clipboard, together with the historical past information.
Note, if you change the 'background run' standing on the settings display, you have to restart the app for this alteration to take effect.
Localization language assist is provided for French, German and Spanish.
No personal information is distributed to others without the person's direct actions.
Applications of 'Precision GPS Pro' embody navigation, geocaching, prospecting, emergencies, surveying a property, observational astronomy, and archaeology.
