Matt's GPS thread...

[jw.]

We left off somewhere about...... me saying that I thought, for speed calculation purposes, the gps software would discard the spurious fixes. There were posts after this but the site crashed before I got to read them.

Over to you, Matt.

[jw.]

Yes, but if it's averaging then the fix that indicated the +5mph would be part of the averaging. Eg. say it's averaging over 10 fixes, if 9 of them are good then that one will have a limited effect.
Do you know whether displayed fixes are averaged?

I can see that phrase getting some use here on boatmad! (along with "Searay Speedo".
:cool:

[Jon Fuller]

It wasn't deliberate, just forgot to toggle it from 'OFF' in the Tech Q&A forum, rest were done;)

[Rockey]

[Jon Fuller]

Gaffrig Competition Gauge.

Here's one I prepared earlier:

You'd assume there's some filtering wouldn't you, but at 65mph, an extra 5mph might be below the rejection threshold

I think You'd have to add 5 to every sample to continuosly to get the average up by 5.

There could be errors on the negative side too.

You could end up with a reduced speed if the system shifted your position the other way.

The M/Boat mags did a similar position trial.

[Jon Fuller]

It's not fair when an IT expert picks on a poor Marine engineer, who's already out of his depth! this is in my black book Mr K!

[Johnny Rocket]

I wasn't picking on you, I was picking on Matt :D

[Jon Fuller]

I've turned off 'HTML' in posts on all forums exept 'Torkin bollix' which I'll do later once everyone's seen Missus's smilie links.

Joking apart, thanks for the wake-up call John.;)

[Jon Fuller]

Calm down everybody! no need for upset.
We'll just suck it and see.

I resent your implication that I would knowingly expose boatmad to undue risk. I can't be bothered to argue the toss so lets call it quits. It's Jons forum and if I post I'll follow his rules. Fair enough! No offence meant :D

[jackeen's Missus]

Oh No...

I'd just trained myself up in putting them on via HTML...

I hope it's not going to be complicated !!!!

However security is important and input from all you IT eggsperts is welcome...(apart from Richard B's wevver forecasts!!!)

Can someone explain why HTML is an 'issue' ...???

Is it that dangerous?

(A yes or a 'nayMissus' will not do

:laugh: :laugh: laugh:

I need dot-to-dot explanations!!!)

Naymissus

[jackeen's Missus]

garfish????

Did a smiley gobble his definite article???

Missus ??????

[Petrol Head]

The Wazzok pin in the smiley engine right ... it could, if you're not careful endup thinking outside of the box and potentially allow the hetrogenoius and homologated systems to holistally approach a scope creep of the model, in the heirarchically openended object orientated topolgy of the seven layer pre emptive mutli tasking knitting pattern forwarding deamon.

Yes ...I think thats it

Poor Matt. He starts a perfectly reasonable, nay, some would say useful, thread on GPS and it's now deteriorated to toilet humour. I apologise to Matt (and the more sensible members of this forum) for the behaviour of Ice Kiddie and jackeen's Missus.

[jackeen's Missus]

Oh behave.!!!

I've replied now...(to pm)

Missus:D

You're right tho' Apologies everyone!!!
