Hi, i’m working on a venus gps. I had to filter data with a kalman filter, but i need raw data from gps. I read the gps has an internal filter on data. Can i obtain raw data?
thaks.

Raw data as in satellite streams? It’s not going to provide you with that.
The filtering they are probably referring to is the different modes you can set according to if the unit will be used in a pedestrian, car, or aerial vehicle.
Some filtering settings are also available for location pinning that you could turn off.
Care to talk more about your project? 
Thank You for your answer.
I thought that the Venus could provide us with unfiltered datas. But I have just read that the NMEA standard - and satellites too, i think - provides “filtered” datas (pedestrian, car etc…).
So, i’ll try to do Kalman with those datas.
Bye,
Alessio.
