The Fourth Amendment is very relevant here, since the whole reason why cops/prosecutors/judges need to have probable cause is because the Fourth Amendment demands having it prior to issuing a warrant. While most people might be aware that cops need to present a warrant before letting them into their house, not everyone is so aware of the details stemming from American constitutional jurisprudence.

Then there's the legitimate question of how much weight should be placed on GPS evidence. Courts and judges don't just blindly accept GPS, since even it has flaws. It's very good, but degraded GPS can have a circle as wide as dozens of meters, which is enough to implicate the wrong house, or the wrong apartment in a complex. For a related example of geolocation gone horribly wrong, refer to the MaxMind Kansas glitch.

With all that said, your conclusion is correct that some judges just simply don't want to do the required probable cause analysis, and neither do some cops.
