Globalsat 308 - Poor Reception ?

AllenJames · Regular Visitor Joined: Oct 30, 2004 Posts: 78

I have recently bought a globalsat 308 to use with my HP 2210.

I sorted the problems with it dropping connections and all seems to work superb when its in my car sat on the dash.

I tried to use it the other day while walking along, Ipaq in one hand, BT308 in the other.

All is well, but I only get 2 maybe 3 sats tracking me.

As soon as I put the BT308 down (ie not hold it in my hand) it will track up to 8 sats.

Is this a fault, or is my hand somehow killing the reception ?

It's your hand working as a shield. This can happen on some GPS Receivers. Sometimes it's better to hold it by just placing it on your palm, or putting it in a shirt pocket.

Hi there,
i see in your post that you solved the problem with your 308 dropping the connection. How did you do it? mine keeps freezing up during journeys and i have to switch the ipaq off and back on, reselect the 308 to get it back up and running and this is with 7 sats locked in.

Cheers

Hi Graham,

You say your setup keeps 'freezing up'. By this do you mean it keeps saying that your 'GPS Position Unreliable' when it 'freezes'?

I see that you are using a 2210. Are you also storing your maps on SD card?

If so, then your card (or its' interface) may well be the problem.

I would strongly recommend that you try using a CF card for map storage as this may well solve your problems. A good quality SD card with good read speed may also do the trick but testing with a CF will point you in the right direction.

If your problem is something else entirely, then I apologise for presuming. I use a 2210 and 308 however and think that the above will help enormously.

Hi Steve,
thanks for the reply, actually the PDA is a 2215 although i don't think there's much difference. The programme freezes and just shows the speed at which i was moving at the time. Don't think there's any message about the gps position being unreliable, but i'll have to check on that later today when i get my car back off the wife. As to the sd card, i'm going to try another ( Kingston 128mb) and see if it makes any difference. The other one i bought off ebay its called a Phast 512mb. Haven't had the system all that long so i am still learning. The system came with the Kingston 128 with GB installed, i bought the other so i could have France on it as well.

Hi there,

The 2210 and 2215 are one and the same - Transatlantic marketing being the only difference I think.

That being the case - I can't reiterate too strongly - try a CF card. The 2210/15 SD interface is a well known source of the type of problem you are describing.

Thanks for that steve, i'll probably end up doing that, but first i'll try the updates suggested by tomtom. Don't know if these will work but obviously they must have had other complaints and worked out a fix. Although if it is the sd card interface causing the problem i dont see a twek to their software sorting it out, do you.

Hi Steve,
well things are looking up, used the system twice for about an hour each time and no freezing, navigator ran like clockwork and got me where i was going with no hitches. Looks like the fixes worked, but i'm gonna keep everything crossed anyway. Going to France in two months so i want it reliable for that. Any idea if theres a database of french speed cameras anywhere?

Hi,

Yes there are files of French speed camera's available - check through POIEdit.

However, my understanding is that it is not legal in France to use the data on the road so I personally do not use them while driving over there.

There is a website that lists them fairly graphically, so you could study this before you finalise your route. You should be aware that the Gendarmerie don't mess about painting them yellow and practice the art of subterfuge in pursuing speeders. Confused
