MAP THIS! version 0.461S (beta) with support for PSP-290 GPS accessory

[deniska]

Just to report something unusual...

I have just recently bought a white psp with original firmware 2.71 and TA-082 motherboard. I got it down to 3.03OE-C with the 2.80 downgrader.

Thing is, when I run Mapthis on this psp, I found that it gets a fix as fast as the green proggie and after a run for some time, I can get full 5/6 bars.

Before this, I was using an older black psp with 3.03OE-C and using the same memory stick with the same files, performance was poor, hardly getting to 3 bars, same locations.

Well, it might be the weather or other factors, but I just want to say that I might have been wrong before about Mapthis because the good results with the new psp has happened consistently(more than 5 times today with at least 10mins run). If anyone has similar experiences, please feel free to post. I will post if results do differ again.

Interesting...
I have 3 theories about this:
1) slightly higher output voltage on TA-82 thus more power to PSP-290
2) less electical noice/interference that the new chipset provides..
It would be interesting if someone ran this receiver through some kind of usb extention cable, taking it away from PSP, to see if that makes any difference...
3) satellite luck ...

Anyway, keep testing..
thanks for the report..

Has anyone translated what it reads on the instruction book for PSP-290. It's all in Japanese but the pictures indicate that (I believe) best reception comes when you leave the GPS receiver "flat" and not upright. In other words, the GPS receiver has to be perpendicular with the psp.

I've noticed that it gets best reception this way too. Anyways, I was just wondering if anyone read Japanese and could decipher all of this.

here you have the instructions in some lenguages

Sorry to come to this forum with a question. But I have been working with the PSP-290 GPS device for over 6 hours with the same trail and error as this user: http://www.dcemu.co.uk/vbulletin/showthread.php?t=51350

The only difference from me and this user is that I am working on a 1.5FW with the latest DevHook Emulator (v0.52) Emulating 3.03.

My question is, will MapThis! (0.461S) work with DevHook v0.52?

Any information would be greatly appreicated.

i did a somewhat extensive test on my PSP-290 with MapThis and the green proggy for 2 hours around my area in toronto yesterday.

my conclusion confirmed that the best prx combination is with a 2.71 usbacc and a 3.03 usbgps. it performs slightly better than a 3.03 usbacc and a 3.03 usbgps. (and of course alot better than a 2.71 usbacc and a 2.71 usbgps.)

it was especially true on the green proggy as i would definitely get a fix within 1 min 30 sec, most of the time within 1 min. (and for once it took less than 20 sec, and it was done with a 'freshly copied' set of prxs! meaning it hasn't been ran with the program before and that it contained no satellite position data.)

when i tested the EXACT same set of prxs on MapThis (i copied the 2 prxs that has just been used successfully on the green proggy over to MapThis, meaning the usbgps.prx contained as much as 12 satellite data, supposedly), it is a different story. MapThis had trouble detecting more than 2 satellites most of the time, let alone getting a fix. and it would have to restart my PSP-290 once in a while. (the program even completely stopped (gps state: off) my PSP-290 a couple of times when i tested it with a 3.03 usbacc and a 3.03 usbgps, fyi.)

therefore it confirmed that the green proggy DOES get a fix alot easier/faster than MapThis.

all of the above tests was done with the new eboot, 0461S_1 (mhz: 222), inside an idle car in an open area, with a white japanese original firmware 2.0 psp (running 3.03 oe-c) at the same position at all times.

it was even more difficult to get a fix with MapThis when the car was moving slowly.

Hope the information helps...

Thanks angel, that was very helpful information. (I just tried your method and I also got a REALLY fast fix (within one minute). I also noticed that it found a lot more satellites than usual.)

Has anyone else tried loading directions onto MapThis? Whenever I go to "POI LOOKUP" and load the directions, it gets to "loading data" and freezes and then the psp shuts off. I notice that it freezes when I do a "POI LOOKUP" AND the "TRACK UP MODE" is on. It seems like it cannot do both at the same time.

Whenever I can get POI LOOKUP not to freeze, it just "blinks" "loading data" real fast and does nothing, i.e. the map does not change and just stays the same.

Anyone get the same problem with freezing? Anyone get directions to load up successfully?

I tried it a couple of times, works great for me. No problems there.

BTW, angel and PSPLaywer, do you guys have TA-082 motherboards for the psp as well? Just curious to know. The green proggie still works best in comparison but I noticed a vast improvement from my new psp.

No. I have an original psp that I got on launch day in US.

I am, however, running on 3.03 OE-C; just FYI.

upon further testing, setting the initial location to 1 gave me the best result of the three. i got an average hdop of 3.4 (3 bars) with initial location 1, compared to an average hdop of 2.2 (2 bars) with initial location 0, and even had trouble getting a fix with initial location 2.

and yes, with the gps logo of PSP-290 facing upward does provide the best reception.
