Hello all, would it be possible to build a inertial dead-reckoning position calculating device (starting from a known position) using accelerometers, gyroscope and magnetometers? Thanks for any hints.
Hello all, would it be possible to build a inertial dead-reckoning position calculating device (starting from a known position) using accelerometers, gyroscope and magnetometers? Thanks for any hints.
If so, what would be the highest accuracy and which components would be required?
Hi Diego,
Thanks for directing me to applicable hard- and software. I will take a closer look at them. I understand that the accuracy will not only depend on the resolution of each sensor but also, and maybe principally, on the algorithm which fuses the sensors together.
Kind regards,
Dirk.

Hello Dirk,
For your application could be useful for you to use NXP Sensor Fusion. Sensor Fusion is a process by which data from several different sensors are fused to compute something more than could be determined by any one sensor alone. An example is computing the orientation of a device in three-dimensional space. Here you could find more information about NXP Sensor Fusion.
For sensing, you could use the FRDM-FXS-MULTI-B. The FRDM-FXS-MULTI-B is a sensor expansion board, that offers 12 sensing axis, and could be used by the NXP Sensor Fusion software. This board has an accelerometer, a magnetometer, a gyroscope and a pressure sensor, all in the same board. This board could be used by the FRDM-K20D50M, FRDM-K64F, FRDM-KL25Z, FRDM-KL26Z and the FRDM-KL46Z, development platforms. This sensor expansion board, also contains a Bluetooth and SD module. Here you could have more information from this board.

In any case, you could use the FRDM-STBC-AGM01. The FRDM-STBC-AGM01 is a sensor shield development board that only offers 9 sensing axis, and also could be used by the NXP Sensor Fusion software. This board only has an accelerometer, a magnetometer and a gyroscope. Here you could have more information form this board.

I hope this information could be helpful for you.
Best regards,
Diego.
