Have you got a slow fix? Don't worry...I'll improve it!

[sAnTeE]

Eheh, I didn't want to believe to it, but it seems to work:D

Install this small freeware and run it BEFORE you launch any GPS program: it downloads approximately 35 kbytes on your ppc and it allows you to have a rapid fix (a warm fix even if it should be a cold one).

Try it and write about your experience.

Ciao :D

[sAnTeE]

I add some explanations on the program.

QGPS: improve your TTFF to seconds!

If you have a PPC with built-in GPS - this software is for you.
This is a small freeware that downloads Ephemeris data to your PPC using an internet connection with Activesync. If your GPS was off for more than 4 hours, then the next time you start it up you get a cold start , where the Ephemeris data needs to be DL to the receiver. This can take a few seconds to a few minutes, depending on your device and location.
The software downloads this data to your PPC so that you , in fact , get a warm start!
Just start the program, click the Connect button (no need for the 10 days data), and within a few seconds , you get the most up-to-date data. Now go outside and start your GPS program - you'll get a fix within 10 seconds!

sorry ... no fix after 30 secs :(

OH Yesss. Very cool! This worked for me. I did a soft reset which usually means the GPS takes 1 minute or more under the most ideal conditions, much longer if you are moving or around buildings. After downloading the data with this app, it locked about 10 seconds after the GPS was recognized by the system. However it failed to initiate a connection automatically, I had to manually connect to IE to get a connection, then it downloaded the data every time.
THANKS!

[Cyrus Kourosh]

Tried with an HP Travel Companion iPAQ rx5935 of a colleague here at work and it works fine too.
And as Matterhorn said: It failed to initiate a connection, I have to start IE first... then download the data.

Thanks a lot.

97 secs to have a fix , i am a quiet disappointed :(

i use the last radio

I did not compute exactly the time needed for the HP. It was something around 1min too. But without this soft... we was around 5 min.

Also... It highly depends on the area where you are (discovered area… buildings...)

I also had to establish the connection manually:)

i didn't establish the connection manually

Santae, which version of q-gps are that you have posted? 2.03???
i found here 2.03 http://forum.pocketpcitalia.com/download/gpsct_1.27.2147.0. 4.1099.123.0.it.cab
can someone load on rapidhshare?

[psxsnake]

exist 2.06 version too

Yes, this was stolen from http://www.avaricum.net/ and it only works on the Globallocate GPS chip of the HP hw6515/6915, it will have zero impact on the Qualcomm chip of the P3600 or of a SiRFstarIII based unit. This thread should be locked before more people waste their time with it.

OMG...placebo effect! :eek:

[mregeling]

stranged, because i get now a very quick fix.

faster then before.!!!!

[Guybrush]

me too... from 4 minutes to 67 seconds

Actually, I think "stolen" might be the wrong word, it looks to be an open download to me.

[YYYYY]

Normally it takes about 5 minutes or longer in front of my window to get a fix, no I got a fix in less than 1 minute, thanks man thats great!

[alnajmi]

It works great for me. Way faster than before. Thanks

I totally agree (apart the world stolen).
I think (maybe i'm wrong) that to have a Istant Fix you need not only a program that download the ephemeris, but another piece of software that in some way tell to your gps chip: "this is the current satellite location". In this way you can speed up the fix.
But the avaricum Qgps in this case can ONLY make an ephemeris download.

[J.P.]

Is it between my ears or do it work whit p3600 too?
I thougt that i had a faster fix but if other persons say dat it can't work with the p3600 it must be between my ears...

[ZakMcRofl]

How are you testing? First without fix, then with? That would explain the improvement, a second fix is always quicker.

Best test would be to first try with fix, then without. I don't know enough about this stuff but maybe someone wants to do a proper experient.

+1 and i made the test yesterday after work backing home : this stuff does nothing :)

[YYYYY]

For me it accelerates the fix as I said, before this tool it took about 5 min up to 15 min fpr the first fix, with this tools less than 2 minutes, both were cold starts

[ulischultz]

Good improvment on my trinity also!
When I use this tool and start tomtom after that and go to the gps details, the position of the satellites are already visible! It then takes only short time to the first connection. This tool does exactly what it should do.
Perfect would be a script, that does an update via activesync every day.
Can anybody do that?

[dew.man]

There's a huge difference between Time To First Fix, and a Hot Fix, and a complete reboot DOES NOT insure you're doing a cold start as the GPS retains memory.

To truly check/compare the effects of this app, you must do a series of tests timing both cold and hot fixes, with and without QGPS, and at least 4 (24 would be better) hours apart without any GPS usage in between.

In doing so, I find that qgps has no effect, and a cold fix still takes me 3 minutes from the same location with or without the app...

I agree with you notice the same here, no effect.

[chiman]

I agree with you notice the same here, no effect.

Same for me. I've tried it after a softreset but fix time is not improved.

[Noony]

Same here tried it - but no effect

[DikkeDoei]

Apart from people experiencing the placebo effect (:P) the following theory might clarify the confusion:

The program features A-GPS (assisted GPS) which needs to be supported by both the integrated chipset (Sirf III and GPS-one (Qualcomm)) and the mobile network. In most countries A-GPS is not (yet?) supported by mobile operators. I know Orange is maintaining SUPL servers in some countries, and reportedly mobile operators in Sweden and Switzerland are ahead.

Aren't the most clear improvements reported above stated by Swiss members (some of which) using Orange?

I think that's the clue: the Trinity has Qualcomm GPS-One integrated (part of its MSM6275 chipset) which supports A-GPS but only benefits from it where mobile operators support A-GPS.

By the way: the A-GPS functionality can be enabled by register as well, and does not need a separate program at all.

... By the way: the A-GPS functionality can be enabled by register as well, and does not need a separate program at all.

Did a quick search, but did not find it. Anyone can point to the hack, or just tell?

With the registry hack, does it poll constantly to establish position, and if so, how much does battery life suffer?

Thanks.

[YYYYY]

Yeah, where can I find the registry hack?Nothing to see in the registry about agps

Guys, this program (qgps) has nothing to do with A-GPS! It is the same type of program found on the P3300 that (as has been said before in this thread) downloads ephemeris GPS data for use by the receiver to reduce TTF. Here is an excerpt from a more detailed post I put in another thread that has nearly the same subject:

------------------------------

A-GPS is a service provider dependent and subscription based ($$$) information source that provides data on the position of the GPS satellites that will "assist" the low sensitivity GPS receivers housed in some phones that are far less expensive than our black (or white) beauties. I am quite certain that the Moto Razr doesn't have a Sirf or a Qualcomm GPS-one chipset! Verizon VZ-Navigator is a prime example of such a service.

QGPS has nothing to do with A-GPS. It is simply a program that performs a single download of the most up-to-date data on satellite positions from the internet and uses it to help the GPS receiver reduce TTF. It must be updated about once every 2 days to be of any help. A-GPS, on the other hand, communicates continuously with the "assistance server" through a cellular network (again...$$$) to share the processing load in tracking the GPS sats. Thus, weaker (and less expensive) GPS receivers can be used in the phones which are equipped with A-GPS. Here's an excerpt from the Wikipedia:

"A-GPS differs from regular GPS by adding another element to the equation, the Assistance Server. In regular GPS networks there are only GPS satellites and GPS receivers. In A-GPS networks, the receiver, being limited in processing power and normally under less than ideal locations for position fixing, communicates with the assistance server that has high processing power and access to a reference network. Since the A-GPS receiver and the Assistance Server share tasks, the process is quicker and more efficient than regular GPS, albeit dependent on cellular coverage."

-------------------------

So let's put this puppy to bed. QGPS doesn't work on the Trinity (at least there is no program to date that works for it.) And unless your subscribe to your wireless provider's A-GPS service and somehow enable it on your trinity, you are not getting a faster fix that way either.

Let's just enjoy the fact that we have the capability at all...it wasn't that long ago that GPS on the trinity was only a vague rumor on the net. Silver lining, people...silver lining!!! ;)
