Measure GPS latitude, longitude, and altitude
Simulink Support Package for Android Devices / Sensors
Get the latitude, longitude, and altitude measurements from the GPS receiver on the Android™ device.
The Location Sensor block has three outputs:
Alt. Each port outputs a
scalar value. The format of the measurements is decimal degrees, with
six places to the right of the decimal point. This number of decimal
places has greater accuracy than the GPS receiver provides. For example,
at the equator, 0.000001 degrees is approximately 11.1 centimeters.
GPS accuracy is typically measured in meters.
The GPS measurements reference the most recent revision of the World Geodetic System (WGS84).
If the GPS receiver on device does not support altitude measurement,
then the output
Alt returns zeros.
GPS must be enabled on the device. If
GPS is disabled on the device
Device does not contain a GPS sensor
Simulating without a device
this block outputs zeros. See Block Produces Zeros or Does Nothing in Simulation.
- Sample time
Specify how often the block reads the sensor.
Smaller values require the processor to complete the same number of instructions in less time, which can cause task overruns.
