IES Accelerometer GPS Arduino Shield IES-SHIELD-GPAM.

The IES-SHIELD-GPS and IES-SHIELD-GPAM modules are highly integrated multi-channel simultaneous GPS and GLONASS positioning systems. Both modules include programmable analogue input/digital GPIO. IES-SHIELD-GPAM additionally features an on-board 3-axis accelerometer. Although both modules have an Arduino-shield format, they can also be used with a Raspberry PI SBC. Both modules feature I2C communication with the host in order to leave the serial UART [Tx/Rx] port free for other functions e.g. wireless communication.
GPS data is stored within internal registers which are updated once per second and includes:
Latitude (i.e. vertical)
Longitude (i.e. horizontal)
Altitude (metres)
Time & date (UTC)
Heading (True)
Speed (kilometres per hour)
Satellites in view
The accelerometer of the IES-SHIELD-GPAM can be used to determine inclination for mobile robot applications.
Give your Arduino or Raspberry Pi robot the ability to know where it is, how fast it’s moving and in what direction.
