Can you navigate without using GNSS?

[capnsensible]

Easy question.

Me? Yes.

 

[Praxinoscope]

Yes still like to sit down and DR on paper charts, I use the GPS to see how far out my calculations are.

 

[Poignard]

I suppose I can, seeing as I don't know what GNSS is.

 

[Skylark]

No, not since Calshot chimney was demolished ??

Don't forget FBC on the Clyde!

Routine six or three minute fixing on passage. FBC bears...That!

GPS was the original and generic term for fix in space. In these enlightened times, with other space junk up there, they are all called Global Navigation Satellite Systems.

Side question. Does anyone remember Differential GPS prior to Selective Availability being binned?

Global Navigation Satellite System, a broad term that covers GPS etc.
Captainsensible beat me to it.

 

[capnsensible]

Or Decca?

And why people called it Desmond?

There is a potential Lakesailor here.......

Think I still have a Decca unit lying around somewhere as well as an old RDF.
Should really do some house/shed clearing.

 

[capnsensible]

Re. Terminology. At Joint Sevices Sailing, RDF was always called 'the sick box'.

Yes, I’ve never given it up. My YM certificate is dated 1992.

Oh yes. And on the subject of gps, how about converting osgb to wgs Datum’s and seconds to decimal minutes.

Desmond was singer of the well known song “my ears are alight”, wasn’t he ? ?

Sprog.

 

[Chiara’s slave]

Sprog.

I’m sure, yes. 1992 puts me before the real age of GPS on leisure boats though. My first set was a hand held, NMEA to a Yeoman. Very advanced, at the time?

 

[Andibs]

And the isrealites (spelling)

Only the Israelites call it that.

Side question. Does anyone remember Differential GPS prior to Selective Availability being binned?

Yes, i had a Diff receiver fitted alongside a Garmin 128, it picked it corrections up from point lynas, it worked very well for wreck fishing, but my Lowrance eagle paper sounder interfered badly with it, shortly after i bought it they switched selective availability off, i was left with a useless toy.

 

[Buck Turgidson]

You've probably all got diff without realising it. If your GNSS is SBAS(WASS) enabled then it is a differential GPS.

As to navigating without it.
Yes I can

 

[SaltyC]

Hmmm, still have and use the Yeoman, big picture on paper and x marks the spot if all dies.
BUT when paper dies will have only old uncorrected charts ? ?
