Re: Inmarsat - Receiving Data and Plan Costs

Sounds about right VB. What are you doing for weather info? I do have a sony worldband receiver, so with any luck I can get weather with this. Plus I can have someone SMS me weather info over the sat phone anyway to alert me of any serious weather. But I would like to have the ability to use the phone for weather data too. Not that I can go outside in rough weather to get it connect to a satellite anyway.

msponer. After messing with the UGRIB software I can get data for an area about the size of Australia (isobars and wind minus rain) with a resolution of 1 degree for 5 days every 12 hours for under 100kb.

Quote:
You can use Sailmail's email autoresponders without subscribing to their service. They are nice like that. You send an email to one of their computers, which responds with the GRIB file you want.
How exactly do you do this?

Re: Inmarsat - Receiving Data and Plan Costs

Autoresponder instructions for SailDocs are here: Requesting grib files from Saildocs (2010-07-08)

It's quite cool -- the computer will even respond with "spot" forecasts, which is a text copy of a GRIB at a specific place (say, if you are just anchored and want to check that the wind won't come up a whole lot).

Here's a ~4k GRIB query I used to request in the Sea of Cortez, which is the box of 24-26N, 109-111W, 0.5 degree detail, every 6 hours for the next 4 days, only the wind information: 24N,26N,109W,111W|0.5,0.5|6,12..96|WIND

So, yes, getting all the data for something the size of Australia would be expensive. But I am not sure it's necessary.

Thanks
I haven't made any plans for weather yet. I figured I'd see what the boat has once we find her and then learn to use what's there, or upgrade to something current if need be.
The big challenge is to find the right boat. I've got the time to get the boat cruise ready and then start our cruising life wherever that happens to be, but heading back to Australia as seasons permit.

Yep.

Gribus sends only a very small request file and the download area can be any size and content you wish (well, nearly, wave info is not there). Also, US radiofax can be gotten via autoresponder.

Many ways to go.

Iridium OpenPort expensive? Man. Go get Inmarsat broadband. Now this can be expensive! I bet OpenPort is somewhere mid-way (?).

Re: Inmarsat - Receiving Data and Plan Costs

I have been using inReach by DeLorme (it uses the Iridium satellites) and my Droid smartphone for a month, testing it to see if it’s the comm device I want when I go off shore. I am getting 250 messages (8.33 messages per day is allot more than I need) and unlimited tracking for $50 a month. It has tracking and auto SOS with coordinates built in.
I like it allot so far and may drop down to the $26 month 100 messages and 25 tracks which would is no problem as it use very few tracks mostly one at daily intervals for a month to 45 days. I could let it track me every 10 minutes for 30 days that would be an interesting trip to review.
For weather I’ll use a SSB receiver which cost me $150.00.
I need weather and two way communication I’ll pick up detailed longer emails when I am near shore.

Yes, DeLorme and its clones are becoming the thing in many ways.

This: Features

Promises some form of wx alerts, two way messaging, and plenty of other goodies.

They claim it can be rented, hence you save on bullet hardware costs.

Re: Inmarsat - Receiving Data and Plan Costs

Here:

"... Alerts

1) Cerberus' patented alerting system lets you receive critical weather, health, geopolitical and news alerts in real-time, based on your location or a location of your choice.

2) Don't see an alert you'd like to have? Create your own on CerberCenter. Share it with other Cerberus users or keep it private.

..."

Gods only know what they mean but who knows maybe there is a way to create a 'high winds' alert? Probably the company will respond when one is actually willing to buy the thing.

Cheers,
b.

I was not talking DeLorme I was talking the Briartec gizmo. It can be rented. One can rent it for the passage and so avoid the immediate full cost of the hardware. Irrelevant to some but perhaps of value to others.

Re: Inmarsat - Receiving Data and Plan Costs

I'm also on the verge of picking up one of these phones. We are about to leave CA sailing to Hawaii, and really just need this phone to get some weather info (since we're sailing during tropical storm season), and emergency communication.

I will probably buy a used phone and a data package, then sell it when we get to Hawaii.

It seems to me that the simplest way to get weather info, is to give our friends/family a job to do. Basically just go to this site: High Seas Forecast (NE Pacific)

copy/paste the text into an e-mail and send it off to us

i suspect we will be completely satisfied with this information each morning. The rest of our forecast will be created by us from our cockpit ;p

I use an isatphone pro to download weather at sea combined with xgate for compression, but I've been told that the sailmail app can work with it for free compression. The charge is by the minute, so it's usually about three dollars to get weather. I use a non USA capable sim card so there is no monthly fee. 170 minutes (that I got with the phone) has held us over for three months of weather and the occasional call, but I try not to use it. If we have an Internet connection on our first gen kindle I use that, or if we have a cell sim card for the country we are in and have service, I use that. It has been an inexpensive, very nice thing to have onboard.

Re: Inmarsat - Receiving Data and Plan Costs

I got 2 x 200 unit sim cards and the phone is saying "operator determined barring" when I try to make calls. The first card done this after only 75 minutes and the second card also done it way before the credit was used. Does anyone have any idea what is going on?

This is really hard to fix when most places do not have internet and I obviously cant use the phone!

Re: Inmarsat - Receiving Data and Plan Costs

Aussie members - have a look at the government's sat phone subsidy scheme. This is what we did and it saved us half the cost of our Inmarsat phone. To be eligible you just have to be out of mobile phone coverage for a certain percentage of the next two years (within Australia) i.e offshore, remote areas, etc. Apparently the scheme ends in 2013, so make like a bunny and hop to it!
