[PRJ] Inertial Navigation Possible

---

Hi all,

Since the Touch Diamond has accelerometers in the X Y and Z space axis, is it not possible to try and create an Inertial Navigation System. For those who are not sure, it INS uses the accelerometers to assess the movement of the device. So long as the user states the start point and north orientation do you think it possible to do it and to create the software. If it is, then we could do without GPS, afterall, aircraft have used INS for a long time now (albiet theyalso used a gyro). It's not as accurate as GPS but it'll certainly work as a navigation device.

Any comments or help in doing this?

Some GPS systems use inertial navigation for better positioning when in tunners or low coverage areas.

The idea could be simple, a program that read the GPS data, mix them with the G-Sensor data and (why not!) with the TMC data recovered from the FM radio and publish them in a new virtual serial port.

But doing it is not so simple

I think its not dificul to trie i already post the idia in other forum, get the gps data, mix whit the acc, and start counting speed changes in forward . left/right and i think we can get a 600m bonus before black out.
600m whit simple formulas, complex ones give you much more.

The idea is simple yes - implementing such system is a lot more difficult than one could imagine though. It'll only be accurate for a short distance, before the errors become so large it's not feasible (due to double integration).
