GNSS-SDR compilation

Written: 17.06.2019 09:58 Written By: Nils Ole Tippenhauer

I received a bunch of emails over the weekend with students having different types of problems while setting up the tool chain. Two tips: a) don't compile things in a VM host shared folder that uses VFAT, b) when compiling the documentation for gnss-sdr, I had a problem with a unicode character in a code comment.  It was easy enough to solve:

 

git diff ../src/core/system_parameters/GLONASS_L1_L2_CA.h

c) As suggested in the handout, GPS lock acquisition might take longer than 2 minutes. We recommend 5 minutes of simulation. Typically, the lock is acquired within 3 minutes.

d) If the spoofing lock does not fully work out, just submit what you have and comment on it.
