What are the specifications for gyro and accelerometer sensor for navigational system

[iTdl]

Hi,

I want to design a low cost inertial navigation system integrated with GPS.
can anyone let me know selection criterion (specifications) for gyro and accelerometer sensors?

thanks in advance.

What kind of long-term stability do you want to design your system for? In other words, how long of a GPS outage should this system be able to coast through? How inexpensive do you want the whole system to be? What types of scenarios will this system be used at? These are the most critical parameters.

A lo-o-ot of effort was spent in this area to date.

Re: navigation sensor

thanks for reply.

If I want GPS outage of 5-10minutes.
The sensor cost be $10-20 each gyro and accelerometer.
Then what should be the noise level, %bias and other specifications for sensor selection.
