Sourcing a GPS Module #8

Closed mattnite closed 7 years ago

mattnite commented 8 years ago

We need to figure out how accurate of a GPS Sensor we can get, and what sort of cost are we going to pay for that accuracy?

Viktor:

$30 Canadian dollars off Amazon

If cheaper than a more precise option, we can get multiple, and compute/compare location off more than one.

Maybe one in the front of the ship and one in the back. 2 meters isn't a very short distance

I really like the idea of multiple GPS sensors and averaging them. However the link you gave is for a compass sensor which will only gives a heading. I'd like to use a cheap 9 axis IMU for that since we also get an accelerometer and gyroscope.
