OT: 3Y0Z Bouvet Island DXoedition

Hi Elecraft community,
This is of course OT but relevant information to all K3 owners who are chasing DX. They are well underway on their ship closing in on South Georgia Island. You can trace the ship's course here: https://share.garmin.com/bouvet It takes a while to update, but it will. I find it humorous that their elevation reported appears to change randomly between 100' under water to more than 100' above. Their main web site is quite impressive but not very up to date and is not interactive, here: http://www.bouvetdx.org/ All the action seems to be on Facebook. On their web site there is a link to their Facebook group in the upper right corner. You can browse all the content without having a Facebook account. There are a number of nice videos, mostly from their ship's departure from Punta Arenas. The ship looks super modern with a ultra modern and high tech bridge. Again, I apologize to those who are annoyed by OT postings, but this is after all the DX expedition of this century (likely the most costly in history) and I have been surprised about how low profile it has had on the Internet. They are qrv /MM (but their activity seems to mostly CW on 40m. I have yet to see a spot on the cluster. BTW, Bouvet Island is a Norwegian possession (undisputed as far as I know) and the crew has two veteran members, Erling and Just.

The ship is not even half way to Bouvet. The only activity by the group so far is 3G9A/MM from the ship.

That is correct, I did not make it clear they were operating maritime mobile (call sign 3G9A/MM) on 40 and 20 CW and ft-8 on 20.

The elevation discrepancies are normal - I see the same effect whendriving around down here in South Florida, randomly dropping to 10-20feet below sea level. The civilian GPS systems are not configured forextreme elevation accuracy, particularly when close to sea level.
The main web site's position reporting may be outdated because, I think,that they're relaying their position via satellite (Iridium, perhaps?) whichcan get pretty expensive. Given the length of the journey, it's probablynot worthwhile providing hour-by-hour position updates. They'll get therewhen they get there, and they'll get on the air after they get things set up. 73, Brandy, N1HO (EL96xh) ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

The elevation changes seen with civilian GPS are the result of two
fairly fundamental issues: 1. A GPS receiver doesn't really "know" where actual sea level is, it uses a mathematical model. Since the earth is ellipsoidal-ish rather than spherical on a large scale, and since there are smaller local variations, the model is a trade-off between accuracy and complexity. On State Route 37 just north of San Francisco, you are immediately adjacent to San Pablo Bay and can see that you're about 10 ft above it. My Garmin GPS pegs my elevation at 61 ft. 2. The second is "dilution of precision," or DOP. The relative positions of the satellites in the sky change constantly, and finding your coordinates is a process of finding the intersection point of lines of position [LOP] from multiple satellites. When the satellites are scattered all over the sky, many of the LOP's intersect at large angles [90 deg is ideal] and the intersection is well defined. If the satellites are more or less lined up in one area of the sky, the LOP's tend to intersect at smaller angles and the exact intersection point is less well defined. This is Horizontal DOP or HDOP. Unfortunately, when it comes to elevation [VDOP], roughly half the satellites are below the horizon at any given time, there are thus fewer LOP's to work with, and the probability of finding large-angle LOP's is inherently lower. Hence, VDOP is usually [almost always] greater than HDOP. Thus endeth GPS 101. I also think they are communicating using some service on the Iridium constellation which is probably expensive, and the ship is only making around 10 kts or so, so more frequent updates wouldn't indicate much. Given the overall expense of this expedition however, communications costs are probably below the round-off.

Course, Governments/Military have overall control over civilian use of the Birds! or certainly use to have, whether that’s still the case I’m unsure!

Yep. The "civilian channel" on GPS was a gift to everyone from the US
Department of Defense, I suppose they could turn it off if they so wish, but it is so ingrained in today's culture that they won't. Years ago, the channel was purposely perturbed to limit the horizontal accuracy to something between +/-100 to 200 meters. It was called "Selective Availability." The US Coast Guard [another branch of the US military] promptly installed GPS receivers in very carefully surveyed key locations, and published the error between the known position and the GPS reported position. They called it Differential GPS. If you had a DGPS receiver, and were close enough to the DGPS receiver, it would use the broadcast error to correct the received position. In the US at least, they're still broadcasting from various sites in the 280 – 460 KHz range which you can receive if your K3 has the new synthesizer [and you have the BPSK decoder and a cheat-sheet for the format]. Over time, commercial interests also began doing this too. Quite awhile back, someone in the guvmint must have realized that SA wasn't really working all that well at limiting position precision on the civilian channel and gave up. The DGPS transmissions continue, or at least did in 2015. So much these days depends on GPS, it's hard to see the "100 ms channel" going away. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 1/24/2018 11:18 AM, Ken Chandler wrote: > Course, Governments/Military have overall control over civilian use of the Birds! or certainly use to have, whether that’s still the case I’m unsure! > > > > Ken..

At the risk of taking us further off topic…..
SA was turned off in May of 2000 by executive order. https://www.gps.gov/systems/gps/modernization/sa/ <https://www.gps.gov/systems/gps/modernization/sa/> The position quality transition brought on by the shutdown of SA was a milestone event for the marine research community (among many others.) This event was captured at the time by many and is characterized by the amazing graph on the page above - fond memories. Some (many of our tiny community) stayed up and watched the data show the transition in real-time - after stumbling around the world’s oceans for a decade it was AWESOME. I’ve been working with GPS/GNSS receivers (mostly on research ships at sea, but some geodesy) since the early 1980s when our “portable” (two full height relay racks) Y-set had two HP 2100s and a 9-track tape drive see: https://www.ion.org/museum/item_view.cfm?cid=7&scid=9&iid=43 <https://www.ion.org/museum/item_view.cfm?cid=7&scid=9&iid=43> (the picture only has the receiver hardware, it took serious comping in that era to derive real-time solutions and log the data. Now our cellphones and watches do it.) Moving that system from ship to ship set the bar for my Compaq “luggable” later on ;-) A substantial part of the early orbit-correction data collection and analysis that led to differential GPS was led by the civilian surveying and geodesy community trying to figure out how to get high accuracy post-processed solutions during SA. (Not unlike the amateur radio digital experiments that led to packet radio… I still do no not take GPS (and GNSS) for granted. -Dale KB1ZKD --- "Getting out there and doing it; that’s what really counts.

Hi again,
Well, the recent posts have indeed taken us farther OT. While the original GPS 101 posting was excellent information, we are now well past the overload on GPS details (and politics). The ship is now well past South Georgia Island. They acknowledge that their ship borne antennas leave them with weak signals (both ways of course). Hopefully that will change once they get their beams up on the island. Can we please drop the GPS subject?

I have a DGPS station less than a mile from my house. It transmits
310-KHz. A few years ago the engineers doing maint. came over to my house to see my antennas and chat. Signal runs -30 dBm on my SDR-IQ (S9 = -73 dBm). At my former job we installed marine VHF radios with DGPS capability. My GPS show my altitude as 38m ASL. 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: [hidden email] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

Hi all,
Look at this video from their ship: https://www.facebook.com/vhotzfeld/videos/g.639362206232014/10213092437043243/?type=2&theater&ifg=1 They have slowed down to 2 knots (from 10-11). This storm might delay their ETA by several days.

Break out the Dramamine.
Some years ago a very seasoned commercial sailor told me; "there's not a man alive that under certain sea conditions, won't toss his cookies". After a few trips, I too learned that to be true. I later inquired about what to eat for breakfast? He said, "bananas, namely because they taste the same coming up as going down." 73 Bob, K4TAX On 1/27/2018 9:03 AM, ab2tc wrote: > Hi all, > > Look at this video from their ship: > > https://www.facebook.com/vhotzfeld/videos/g.639362206232014/10213092437043243/?type=2&theater&ifg=1 > > They have slowed down to 2 knots (from 10-11).

2 knots?
That would usually be too slow to pass enough water by the rudder to maintain steering control. On Sat, Jan 27, 2018 at 17:47 Edward T.

Hopefully, Hal is over 6 feet tall and treading water. [:-)
