GPS signal improvements. NO SCAM !

Hi all, As some of you 'probably' already knew....
I made a small improvement to enhance the GPS signal/lock. Awesome

===Improvement 1===
Get a USB Extension Cable!!

Stick the GPS unit in front of your car window, perferbly top. And drag the cable along the sideways, cable length is 1.5m, should be enough.
Do not put your uni on the top-center of window, the cable length is limited.

===Improvement 2===
Crack your GPS-290 header (white-cover) !!!!
First take out the Joints using slim (-) screw driver, take the joint cover out. You should see a hole.
Then, use a bigger fatter (-) screw driver to stick into the hole,
slowly twist the screw driver vertically, so as to pull out the white-cover. (I believe this is the *only* way to remove the white-cover, SAFELY)
Note that white-cap is firmly GLUED to the (inside) center of the unit. If you want neatness, use a clear-tape to wrap around the naked header.

Naked header consist of
outer area (square): ceramic
inside area (square): silver plate
core area (circle/dot): silver plate

Here is my attached. Notice how I was stoned while I was on it, so I also colored it using a oil-based red pen.

It is a bit shiny as you can notice I've wrap it nicely with a clear-tape. (no bubbles!)
Now, believe me or not, I can get the GPS signal/locks in my ROOM !! (before I couldnt at all!)
MY friend also did this trick and he also admitted that more Sats are seen and GPS locks are so much faster.

note1.
If you carefully look at the white-cover, they are double layered, one clear outside, and one white inside, I've tried very hard to split them apart,
so that I could stick only the clear one back on..

but it seems that they are stuck very very hard at the factory-level.
I even tried the nife.. doesn't work.

note2.
I also cut out the both LEFT/RIGHT sides, because you cannot stick it to far-corner of your window if you leave them out.
Yes, I know I am not going to sell it.

note3.
When you stick the GPS unit to the window, yse a double sided (strong ones, such as 3M) tape to apply it on the "bottom" of the GPS unit (the silver covers).
The whole point is to try to AVOID covering the center. You do not tape the center (the pink areas in my photo) as the tape is already strong enough to hold.

Cheers

Edited:

is it empty ? or am I misunderstood the picture ?
I was expecting a "High Tech Device" inside that white cover....

I really shocked, what's next ?..
if I crack my quad CPU, may I see 4 gnomes calculating datas inside ???

zerodays, I think that most of the reception improvements is due to the cable and not the cover removal.. I removed the cover on one of my units some time ago but did not notice any improvement.. (I was actually hopping to attach an external antenna to it)
But again, thanks for the info.. Some people may find it useful .

mehmetcan, what you see on the picture is just a gps antenna, all the fancy stuff is underneath..

deniska. I've had the cable-extension for a while, I'm fairly sure that white-cap off really did increase the sensitivity and allow it to find and lock much faster than before.

methmetcan, if you've taken out quad cpu, you will see a Core-die, a bit more fancier than GPS, but thats about it. The high-tech stuffs are more like embedded deep inside.

Hello Zerodays,
I have a PSP 290 and removed the cover and now it works perfectly, hehe thanks a lot. :-)

Before I had only 4 max sats in view now it is 9 - 10 max. Thanks Again... I'm from Philippines btw.

Maybe somebody can make a tutorial with pictures, that would be great ^^.

I tried this out and it worked great for me. I went from having 2-3 satellites in my house with no lock, to 6-7 satellites and a lock on 3 or 4 of them. I can sit at my kitchen table and use mapthis! with no problem, and I don't have to have a wire hanging off my psp.

Here's my pic tutorial...
