Accuracy ublox 6M

0 votes
Dear friends, i need to my project a GPS error of +/-5m and I choose the ublox 6M because in the specifications document is indicated: Position 2.5m CEP. But I am receiving positions which have an error of +/-20 meters. Please could you recommend another chip set or i am right to use the 6M?

 

Thanks in advance

Perhaps you need a better antenna, or better placement of the antenna you have.

Note also that even on a perfect implementation, the CEP value means only that during a 24 hour observation 50% of the results are within the CEP value and 50% are outside that value, with no maximum error value specified.
