How to refresh/reload a child browser tab??

I have to create an application where i would be showing a map on the page. On the initial page the map will be small and as user click on the map, a full map with all the results will be opened in a separate browser tab. What i need to do is, when user change the filter/criteria on the parent tab, the child map tab needs to refreshed with updated results. Is it possible to achieve that using jQuery or java script? Please suggest.
