HERO/Champions has a power where you can pinpoint a person by making check. With sufficient power you could know that "John Doe", someone only vaguely familiar to you, is in Bombay on street X, building #y as you action in combat. Kind of like Professor X's Cerebro helmet.
In M&M, there are (at least) two ways to buy this:
OREnhanced Trait, Investigation +10 (or more) Limited to Searching for an individual, LINKED to Quickness 15 (Limited to one task, investigation checks to search a (large) area for a specific person). This allows you to search a 30 mi square area (900 sq miles) in 1 second. Or you could take 1 minute and search a 2,000 mi square (4M sq miles). To reduce that back to 1 second requires 6 more ranks of Quickness (+2 PP).
This costs about 8 PP (5/2 + 15/3)
I like the flavor of the first one. You have a range you can search and you can spend more time (with Cerebro on your head) to get more range. The first one is also NOT a sense. It's a simple skill check and someone can counter it sufficient Stealth.Enhanced Trait, Perception +10 (or more) Limited to mind detection, LINKED to Detect Individual Mind, Acute, Radius, Ranged, Extended Range 5 (-1/100,000 feet), Penetrates Concealment. This allows you make a Perception check in a 19 miles radius to spot an individual.
This costs about 17 PP (5/2 + 14). To search at the 2,000 mi radius range requires 2 more ranks of Extended Range (-1/10 million feet) and is still just a single check. (+2 PP)
The second one, the only defense is Concealment (Mental Sense). And that defense is absolute.
EDIT: Perhaps the first version needs a ranged awareness power so that you have a mental sense with which to make the investigation check....
