If so, is it stable, and what data can the functions get-- just the current location I assume? And anyone know the smallest distance measurable by GPS?

Reason I ask is that I may have to get back into PSP development in the future (and buy the GPS add-on) if there is such homebrew support.

Yes.

Search for a program called MapThis.

It is a full featured GPS application that uses the PSP GPS Receiver (or other ones) to connect to satellites.

I've heard of MapThis, but I'm not asking about applications, but rather about an API. Some sort of API must already exist for MapThis to exist, so I should rephrase my question to "Are GPS functions convenient and stable, and are they part of the official PSP SDK's API yet?"

Man.. GPS can be used to make a truly awesome gaming experience. I have one idea in particular for what would be a portable gaming device focused on GPS and a certain other technology (one which I don't believe is in existence yet, but I'm pretty sure would be implementable), and the game that it would be intended for.. I'm not going to post about that publicly, though.. Google, for example, is a giant snowball of patents just looking for ideas to accumulate (including ones they won't be putting to use within the next decade or two).wq

Sony sells and supports a GPS device for the PSP and has software for it, so my guess would be yes.

Ugh.. I'm talking about HOMEBREW.

Isn't there a UMD that goes with the GPS? WOOT 1000 Posts!!! VETERAN STATUS!

grats!
lol everytime i see your name i think iso lol.

**Josh1billion** · 09-25-2007, 04:30 PM

There's a game called The Shroud, for cell phones, which uses GPS capabilities inside of an RPG. Not sure, but I think it may be online, too. I'd like to do something similar if such is easily supported via the current homebrew SDK.

GPS functions and sample program here:

I'd still go for a serial GPS and just write your own NMEA parser if you
want to aviod the headache caused by using the PSP290 unit.

**Josh1billion** · 09-27-2007, 08:33 PM

Ah thanks for the link. It looks like the functions might be a little complex? I was thinking someone would have an API of simpler functions, like enable, disable, getx, and gety. Heh..

If you start from MapThis! source and flog it's NMEA parser it is almost that simple with a serial GPS.
The examples in that link are for PSP290, and agreed, it's overcomplicated.

Is there homebrew API support for GPS yet?
