The Plot thickens. It now seems that MY destinator is not the only one that is acting up and picking the wrong streets etc, it has replicated on TWO other units as far as I can ascertain. It seems that these two other copies were working fine and now they are acting up, same symptoms as mine, the GPS data being interpreted inaccurately or a datum issue.
Now what "they" or the powers that be "may" have "done" is to fudge the GPS locations whilst the Commonwealth games in on to deter accurate locations for whatever "reason" someone may have.
I am not "saying" anything "untoward" in this post just that if anyone "else" is having this problem with their "navigation" then heed "this".
I am going to "wait" for a "few weeks" to see if "it" returns to "normal"
"Whatever" "that" "is"
"Bonz" aka "KS" of "TI"

Be alert but not alarmed!
Perhaps the owners of the satelites put the fudge back that was there till a few years ago in case someone wants to celebrate the third anniversary of the liberation of Iraq with a pyrotechnic display of some sort.
Can't imagine they'd be too fussed about the Queen's games.

I would
hazard a guess that it is possible to introduce an element of error for a given matrix of coordinates, whilst leaving the remainder of the country/globe unaffected. Similar to how GPS signals can actually be blocked/overridden in a certain area to create a blackout.

Ozi isnt a drama with me either MD as it simply locates at a point, whereas Destinator HAS to be on a road at all times so it gets upptity if a road isnt too close to where it thinks it is. hmmm worried about Mike post

oh ok, I thought you were suggesting that an error was being induced into the nmea data from the sats which would of course affect all nav systems. I must admit I don't know much about Destinator but doesn't it use NMEA data from the sats.
Sam, A selective availability error can be introduced geographically but it's not that fine, I was only 80k from
Melbourne.

Dither can be itroduced locally, with another time signal being transmitted locally, just the same as acuracy can be inprove with a local station transmitting.
Just a matter of upsetting the time signals.

I used my GPS over the weekend and found accuracy to be good.
I doubt they would have turned Selective Availability back on for Australia, little point really - who's going to fire a GPS guided missile at anywhere in this country? They would need the capability of an ICBM to do that or they would have had to have smuggled the equivalent of a Cruise missile into the country.
Far easier to use a ground to air shoulder launched missile from that viewing area to the north of
Melbourne airport or a couple of kilos of P4 on a simple timer in a rubbish bin at Flinders St Station. Actually I'm quite surprised it hasn't happened - yet...?

Oi! when was the last time Osama was a problem with missiles - NEVER.
However, those types have been a problem with location/s, timings & co-ordination though.
Will be interesting to see what happens after the Games are finished and
Melbourne is rid of its 'visitors'. (all of them)

Those who frequent Flinder St station might have noticed the

bins with clear plastic liners for the Games.
Hope they go back to regular

Let us hope none of those nasty people are unsporting enough to place their P4 in a MacDonalds bag before placing it in the bin.

No probs Mike.
I just wonder sometimes whether our lack of terrorist events is a result of increased security or that we don't rate highly enough on the target list. Either way, I'm quite happy for it to continue, event free.

The latter I fear.
In a Western society it's close to impossible to prevent a terrorist attack and since they decided to die in the event it's become even closer [to impossible].
Oz is a long way away from the rest of the world and not considered significant in a political sense - as you suggest; let us hope that state of affairs continues.

P4 (standing for Pow!4) is a lower grade to C4 (standing for CERPow!4) A CerPow is bigger than just a simple Pow.
Lets just hope that the precautions stay effective.

I don't think that it's possible to fudge the accuracy for a certain area. The GPS receiver works by calculating the distance from each satellite and then triangulating the data to calculate it's position on the earth's surface. The satellites broadcast the same signal to everyone - they don't know or care who is receiving it or where they are.

On May 1, 2000, the US government announced that they have discontinued Selective Availability although they reserve the right to reintroduce the practice in certain geographic areas if neccessary.

Yes, you're right Ray. I just read the statement that Clinton made when SA was turned off in 2000. He said "Additionally, we have demonstrated the capability to selectively deny GPS signals on a regional basis when our national security is threatened." It would be interesting to know how they do it.

Selective Availability of the "Civilian" works by distorting the accuracy of the timing signal sent by the satellites.
Regional Selective Availability works by distorting the signal only for satellites over a particualr part of the world.
Selective Availability does not affect US Defence Forces - they use a different encrypted signal which is not distorted.

Hi Bonz,
I think this is a Destinator problem, and not a GPS issue..
I know of at least three people in
Canberra who have accurate positioning with
OziExplorer, and Destinator 3 - when they upgraded to Destinator PN, they are all out by 200m - not aware of any ability to change datum or anything else in PN...
Is this similar to your problem?

C'mon you chappies, where is your lateral thinking.
Canberra -
Melbourne the only
places experiencing 'difficulties'
?????????????????? - nothing seems strange to you about that.
No doubt it is 'they' & 'them' implementing Bill Clinton's so called 'selective disruption' to protect their B u t t s.
Bet he wished 'selective disruption' was around when he was 'talking' to Monica.
Another week or two will test out the Doctrine of 'Selective Disruption'.

Maybe it's just the normal variation in accuracy of the
GPS. They're not really all that accurate, consistantly, unless they use WAAP, and WAAP is not available in Oz. Atmospherics can cause large variations in accuracy.
If the conspiracy theory were to hold true then all of south east oz would be affected. "SA" is implimented on a "regional basis". That means that an error is introduced to all satellites
servicing a particular area. That particular bunch of satellites actually service quite a large area and we would be hearing of more units affected than just in one city, like the whole if Vic, SA and southern NSW for example.
