Re: [Paparazzi-devel] New GPS module from sparkfun

[Daniel Morgan]

I have just noticed that the alt will actually overshoot the actual level. For instance i have landed a few times and it will hit the ground and the gps will continue until its like 10m below the actual ground level and finally level out. Also with the gps modules i have been using i have actually been getting better pos accuracy with the lea-4p.

Daniel, what kind of weird issues did you have? Same problem as Ingo (the data rate was not constant anymore when there are more satellites available).
Did you use the UART, I²C or USB? But it sounds like not enough processing power on the GPS module....
I wanted to use a LEA-5H as well, now I'm getting doubts.

What changes would you suggest making for those of us that have the LEA-5H?

Thanks
