GPS Spew.

Recommended Posts

For a project I needed a test signal for the GPS L1 frequency (1.575,42 GHz), to check that an antenna is properly matched to the enclosure. This design creates a square wave at 1/3rd that frequency, so the third harmonic can be used as a test signal. The resulting Basys3 design works very well for it's intended purpose.

As a down-side it is also an effective short range (desktop) GPS jammer, which might be useful to testing an embedded design's behavior when GPS lock is removed.

Why would the GPS jamming be a down-side? Couldn't you in principle just unplug/turn off the design if you are needing GPS tracking for other things...?
