Not Fixing On Any Satellites

[Liquid Smoke]

My PSP is a 3.10oea, I have the PSP-290 gps and I'm using the PSP-290 GPS TEST eboot to test it. It loads up ok and comes to the GPS State = 3 and then everything else is just = 0 and it finds 1 satellite, but doesn't fix on it, how do I do that?

No I don't have a TA-082 mobo and yes my WiFi switch is off.

Does it fix automatically when the signal is good enough or do I have to do something?

I'm in the Bronx, NY and it finds like 1-3 satellites, but doesn't fix on them. I'm using the 207 and 303 prx files, is that why or does it not matter? Or am I just not getting a good enough signal? I'll try and go to a more open area see if I can get a better signal.

And in MapThis I go into GPS mode and I get no bars.

[exp3000]

i believe this is only a signal strength problem. make sure you are in an open area outdoors with no tall buildings around, play around with the cpu speed and the position on the GPS unit and look at other threads to optimize signal strength.

@LiquidSmoke
When I startup, I get into the GPS settings and set CPU to 111Mhz (press down on arrow keys) and almost immediately I see 5-7 sats and get locked on and fixed within 15 seconds.
*Takes about 2 minutes in my house
*If CPU stays on 333Mhz, it seems to take upto 7 minutes to lock/fix

Once locked and fixed I push CPU to 333 Mhz so Hybrid Maps move smoothly

i have also moded a metal case for the psp this way

so it blocks most of the EMP noise from the psp

with this, i fix within 30 seconds at 333Mhz :eek:

this is the result

I can't see what you did to the case on these pictures. Can you describe it at least a bit ? You modded the original PSP case or is this extra casing on top of the original one ?

[Dynamics82]

do people who used the psp 290 gps in asia have the same problem?

[dreetje9]

Nevermind

[MSI]

It still would be nice to know what _exact_ case did the OP use to make this shield.

ok thanks, i was hoping it was just a signal problem and nothing wrong with the gps or the way i installed it.

i'll try it again, and yeah i was trying at 111mhz

also if im in map this and go into gps mode, does it automatically find and fix onto satellites? like it starts out with the empty red bars, do those automatically get filled to green or do i have to do something to get it to scan for satellites.

[FatesWebb]

yeah, mine took a real long time the first time I used it, but after that it happens pretty fast...

The easiest hing to do in Maptis is turn GPS-mode on, press Start--> GPS info

There you can see if it trackes satellites and if he lock's them.

It could take a while before he locks the sattelites, just keep the PSP very steady (Even holding it in your hands doesn't improve locktime, so usually i lay it down on the ground/grass in its protective case).

And also play a bit with the angle of the GPS-transmitter.

[Liquid Smoke]

alright i'll try that. and the baud for the 290 is 38400 right

edit: tried it, i found like 4-5 satellites but it didnt fix on any, waited like a couple of minutes.

also when im in mapthis and in the gps info screen, one of the things says LOC: 0 and im able to change it to 0,1, or 2 by pressing left and right, what exactly is the LOC? location? if so what does each number mean?

[atari800]

for the 290 - baud doesnt apply at all

as for LOC...
I am wondering what that is too
LOCation?
Satellite LOCk method?

[dreetje9]

Just wait al little bit longer, mine usually locks in about 10 minutes or so, also depending on the wetter.

Just let it lay down, and have patience

Don't know exactly, but I read that it isn't that important to change it to 1 or 2.

It doesn't give you faster fixes and locks

[Liquid Smoke]

i managed to get it to work. i had it all installed fine, just needed to wait a bit. it wasnt fixing when i just layed it down near my window or went out to the backyard but it seemed to work when i went in the car, prob cuz it was more open.

i just laid it on the passenger seat and it fixed after like 2-3 minutes and seemed pretty decent. wasnt that accurate, a little off and not that sensitive, but it was decent for only $60 compared to $200 for others.

[atari800]

I read somewhere in the threads it could be th emaps you downloaded or a bad sync with a satellite throwing you off a bit.
I am off sometimes but I dont mind if it appears I am driving on the sidewalk

:rofl:

[Liquid Smoke]

yeah a little off isnt that bad, doesnt have to be super accurate, but its bad if its showing u like on the next parallel street or something lol, but it didnt do that, but that would be bad. but it just showed me as like on the sidewalk on a smaller street then on a bigger street it showed me on the road, so its cool.

but i just went out again and tried and this time couldnt seem to get a fix. it was around the same area as last time but didnt seem to fix, just found like 2 satellites. prob just fixes much faster on bigger open areas. i'll try around more diff areas and types of settings.

i did modify the config file and changed the meters to feet with the value they gave and changed the speedlimit from 5 to 70, but i cant imagine that being the reason for not fixing.

also the speed limit is in mph right? it was on 5 last time and kept showing it so i assume it was everytime i went above 5mph which was annoying lol.

but can anyone tell me what the LOC means though? i read it doesnt matter much but whats it mean? and whats the 0 1 and 2 values mean?

EDIT: argh i give up, i cant get it to fix anymore, just worked once. i went back around the same area and it finds like 3 sats but cant fix on any, i waited a few minutes to. b4 it only took like 2 minutes. i dunno whats wrong with it, it did fall once, cuz i had it on the dashboard and it slid off and fell so i dunno if that damaged anything? it still seems to work and find sats, but it doesnt fix now, and when i shake i do hear a little thing inside shaking, and its not the screw cuz im holding it while i shake and its like a little thing moving inside? is that normal or is it cuz i dropped it.

oh well i'll prob just sell it on ebay again, its just too slow, i cant be waiting 10 minutes for a fix.

[FatesWebb]

I was driving in the car this morning, stopped at a light, hooked it up as fast as I could before the light changed, and then drove off, and before I came to the next light, driving at like 45mph I had a fix... I was amazed that it could fix while I was moving so fast. It only took like a minute...

[dreetje9]

when i shake i do hear a little thing inside shaking, and its not the screw cuz im holding it while i shake and its like a little thing moving inside? is that normal or is it cuz i dropped it.

Nope, that isn't normal.

Shaked my GPS for you, and didn't hear something moving inside the GPS, so you might consider it broken.

But ofcourse you can try to fix it again, to see if it is really broken or not.

That's not bad at all.

I still havent give it a spin on my motorcycle, hope to do so next week, when where off to Luxemburg.

Gonna be the ultimate test :D

[FatesWebb]

dude,

the motorcyle thing is scary, because if you get even one drop of water on the psp, it messes up the buttons, and what if some asshole hits a puddle, or turns on his winshield wiper thing and gets the psp all wet? or it starts raining? maybe you could put it in a ziplock baggy or something.......

[Liquid Smoke]

well the gps still works like it shows as ON on the gps info and it still finds satellites, i guess i just didnt wait long enough to fix.

so if its still finding satellites does it mean its still good?

also is it best to have it pointing straight up at the sky? cuz i dont have a car mount yet so i have it on the dashboard so the gps is sort of pointing like at a 30 degree angle, not straight ahead but not not straight up either, like a little less than in between.

could that be the problem? or is it better to have it pointing more towards that 45 degree range.

[FatesWebb]

sounds like you didnt wait long enough, and I find that it appears to work better for me to have the gps290 at a horizontal level. (all the way back...)

[Liquid Smoke]

as in folded? or like halfway folder so its perpendicular to the psp

like the psp screen is facing u, and would the gps logo be facing u or facing the sky

also, whats the best prx to use, right no im on 3.10oea and i have the 303 prx's. so which is the best to use for 3.10oea, and where can i find the dl link for it

[An0nJ0hn]

as in folded? or like halfway folder so its perpendicular to the psp

I usually get my best results with the receiver parallel to the earth.

[Liquid Smoke]

ah i c, ok i'll try that out. i guess the signals come out the flatter side of the 290 so it works best that way

edit: yeah it seems to work better this way, i get more satellites when the 290 is horizontal so the logo faces the sky. just waiting to see if i get a fix now, just laid the psp down by the window, gettingl like 3 satellites.

also, theres a thing that says SNR and the numbers keep changing its like in the 30's and sometimes 20's, what exactly is that? is that like the signal strength or something?

[atari800]

SNR is signal to noise ratio
"ratio of a signal power to the noise power corrupting the signal"
or a ratio of what is useful information and what is noise

Better example is;
I am on 1 side of the highway and you are on the other
(or satellites in the sky and psp on the ground)

If there is no traffic, I can scream over to you and you can hear me pretty well
If there is some traffic - you can still hear me but not as well
If there is lots of traffic, you probably can bearly hear me

SNR value changes - like being between buildings versus a open field
Or a clear day versus a rainy day

[Liquid Smoke]

ok i just tried it out again and it worked. found like 3 sats and it fixed on like 3-4 in about 3-4 minutes. drove around a bit and seemed to work fine, glad its not broken.

and so the higher the SNR the better the signal?

[killer@all]

Well i have found out that when i change the config.txt in the mapviewer/system ,,go to the bottom and change this INITLOCATION=8,, i´ve tryed it from 0-8 and 8 was the best and quickest for me

Offcourse i'm going to put my PSP in a waterproof bag or something.

First I just need to make a holder for the PSP on my bike, after that i'll see how to hold the PSP dry ;)

what exactly does the initlocation mean? and would it differ with diff areas or is 8 almost always gonna be the fastest?

First info:

Live in- Northpole, Alaska (yes it does exist)
Firmware- 3.30 OE-A' (A2)
Motherboard- Normal 1.5
Using GPS unit- PSP-290
Using PRX's- 2.71's (only ones I could get to work)
Running under- 1.5 kernal

I followed the guide exactly and before I posted my problems in the beggining, I tinkered with mapviewer a bit. I put it in the GAME330 folder of mine and mapviewer displays my map fine. Also I did try the green progie and both that and mapviewer could find satellites.
But... (yep you knew I was going to say that)
I can't get any satellites to fix into my location (yes I pushed square to turn on my gps and I set my speed to 111mhz), aka it doesn't even bother to zoom in to where I am/ doesn't bother to locate me. I don't want to bother doing POI because I just want the program to work and find me. I stayed outside for more than five minutes and even drove my vehicle for 20 minutes and no satellites locked unto me whatsoever. I gave up after my trials and hopped on this forum to gain some help from the community or it's creators. What am I doing wrong?
Did I need to create geodata?
POI needed?
Wrong PRX?
*Note I put a camprx in my root, the prx's in the mapviewer folder (not % one) and made a new folder in mapviewer call 271 with the prx's inside)*

Most of the time you need to let your PSP rest for approximately for 10 minutes before Mapthis locks the sattelites.

Driving around while trying to fix doesn't give you faster locking.

To lock, just don't move the PSP (It's even better to lay it down somewhere outside), and put the PSP-290 receiver in horizontal-stand.

Just have patience (although I know it's gotta be freaking cold out there)

Mabye the cold also has influences on the sattelite finding- and fixingtime, but I don't know that for sure.

[rapitts]

INITLOCATION only supports values 0,1,2 ? however I'm getting the same problem with No Fix locations, however using the GPSTest (PSP290) and increasing the location to 8 gets several fix locations but still no luck with mapviewer 499.

map this needs to be ran in 3.xx kernel for use with psp 290, make sure your using the right eboots

hope this helps

[TaMs]

Actually that unofficial version of map this contains "INITLOCATION=8" as default so it could be best option, if it even does something. my gps unit finds max 10-11 satellites in wide area, but it doesn't still get enough fix to get good signal (max. 5 fix). And my friend gets like 10 fixes in same place. So what could make this difference?

[specialist83]

anyone can help me? i've done everything i can but when i click on the GPS INFO...everything juz shows 0...what can i do to troubleshoot now?

[AJ_NZ]

Hey everyone, this is what I have found to fix the GPS fixing issue:
Start Mapthis, open your smallest map (I use the global map) before moving or changing zoom levels, press the start button and change the CPU clock speed to 333. Then press select and open the map you want, move and zoom all you want. The chance of freezing at 333 is virtually zero.
If you have a GPS reciever now press start and goto GPS info, press the down key and change the speed to 111, this will ensure you get a fix on the satellites. Once fixed, go back to your map and turn on GPS mode, once your position is located change the speed back to 333.
As with the other posts, keep the PSP in one spot outside in the open while fixing, with the CPU on 111 it won't take long to fix at all.
Also if using a sony GPS-290 make sure the reciever is horizontal (not vertical) see pic http://tkfiles.storage.msn.com/y1pNR_7M_XoFQGCZx20GZ5qE3dghGdUPMgvixbODTskYivAuL9 0ovwK6Yr-AZOnzmmr

I used the 2.71 usbacc.prx and 3.03 usbgps.prx from here: http://rapidshare.com/files/12675731/mapViewer.rar.html
I run 3.40oe-a and have a GPS-290.

Hope that helps. Frustrating as hell to get this to work, but well worth it. Great job everyone. :thumbup:

[sssssss]

Works like a charm.
Thanks Heaps.

[bense]

is this laggy fixing only an issue with the psp-290?

I've thought about selling this and getting a holux if it works better.

[aberz]

Try to use the extension cable on your 290 first.

[ruiproribeiro]

Hi guys,
i just bought a PSP GSP290 and i cant put it to work.

I have the MapThis software running ok, with all the options ok, but everytime i try to get GPS info, it says GPS is "off", and i dont seem to put it to work.

I have:
PSP fat TA-079 with firmware 3.40 OE-A
running MapThis version 0.5.2.0
all mapthis functions seem ok.
Only the GPS doesn't work....:mad:
Already tryed severall settings in MapThis, like changing clock speed's from 111,222,333Mhz without success.
Tryed with diferent settings in INITLOCATION (0,1 and 2). Nothing seem to work.

Can the GPS come damaged?
Is there any way i can test if the GSP unit is working? maybe with a mini-usb cable connected to a laptop?


Any help would be apreciated.

Thanks.

It`s always the same... Why don`t people read the ****ing FAQ? Or the Wikibook...

http://en.wikibooks.org/wiki/Map_This!
Read it

And you Problem could be solved by trying this gps reception (http://en.wikibooks.org/wiki/Map_This!#GPS_reception)
