    I’m unable to obtain position and velocity data from the UM7. I tried both SPI and the CHR Serial Interface (3.1.2) software, but all position and velocity data remains 0, even the timestamps (position & velocity broadcasts were enabled).
    How do I get the UM7 to provide position data?


    The UM7 only provides position and velocity data if an external GPS module is attached.


    I am using the UM7 with arduino board and I need to do measurements at the indoor places. So that the GPS is actually unavailable for me. Is it possible to get position data by setting the registers on the addresses 0x09, 0x0A and 0x0B respectively with the approximate latitude, longitude and altitude values that are obtained from the external GPS provider at the outdoor of the environment?



    Hi Tanis,

    Without a GPS connected you wont be able to obtain longitude or latitude.
    The UM7 simply parses GPS data and does perform some simple calculations however, you would need data constantly being fed into the UM7.
