Sony have released a PSP GPS unit! The PSP GPS receiver is suprisingly small, weighs around 15 grams, and refreshes approximately every second. Currently there aren’t many games or applications that support the PSP GPS, but the list will no doubt grow. There’s at least two applications available now for the PSP GPS – Home Star Portable, which is a planetarium application that can give you information about what’s in the night sky depending on your GPS location – and Navigation Soft, which is a navigation application for plotting and displaying driving and walking routes. Hopefully once the homebrew community get their hands on the PSP GPS we’ll see some cool GPS applications for the PSP.
