GPS Compass

Find direction of travel using GPS only.

Only some Android phones have a digital compass (magnetometer)

but almost ALL Android phones have a GPS receiver.

This app will report the direction of travel using GPS only.

INSTRUCTIONS :

1) Turn on the GPS receiver using the pull-down Android system menu.

The icon may be labelled "GPS" or "Location" depending on your Android version.

Longitude and latitude information will appear on screen once ready.

2) Move 10+ meters in any direction.

3) Press the update button to determine the direction of travel.

The current location and a previous location will be used ( 2 GPS points ).

In order to conserve battery life, users should turn off the GPS receiver

once they have determined the direction of travel.

CONTROLS :

1) GPS log button -> Open the GPS log

2) Update button -> Calculate and display the direction of travel

3) Reset button -> Clear all display data and location updates and start again

HUD :

Distance -> the distance between the two GPS points used to calculate the direction of travel.

Bearing -> the degree clockwise from North in the range [0, 360] that was travelled between the two GPS points.

Center compass -> Displays the direction of travel between the two GPS points

GPS LOG :

Clear -> Delete all log entries. If there are 1000+ entries, the app may run faster once cleared.
