While conducting the RNAV (GPS) OR ILS Rwy 05R approach to MMMX in VMC conditions; I noticed as we flew over MAVEK (SMO VOR) intersection the FMC alerted 'GPS INVALID L; R'. This occurred perhaps one mile from MAVEK. As we were in VMC we continued a stable approach to an uneventful landing. I strongly suspect GPS jamming is once again occurring in the vicinity of the Mateo VOR.
A B737-NG pilot reported possible GPS jamming in the vicinity of SMO while flying the MMMX RNAV (GPS) or ILS Runway 5R in VMC. The FMC alerted 'GPS INVALID L; R.'
