Re: off-line information - satellite stuff
Just got word back from OpenSummit app folks. They do have off-line information. Plus, I just tested it by putting my phone into airplane mode w/o wifi to see how the app starts up. Here is their verbage with some improvements coming...
-------------------- Thanks for reaching out! You can view forecasts offline on the OpenSummit app currently. We are planning to combine OpenSummit and OpenSnow into one app this summer, all under OpenSnow. Our offline forecast functionality is weaker in OpenSnow at the moment but we are planning to make improvements here so that you can view the last available forecast (from when you had service) while you are out on the trail. Thank you so much for your support and please let us know how else we can help! |
Water Crossings in Y2023
There has been some group conversation about snow levels impacting the JMT this year, but I don't recall a lot of discussion about how water crossings will be affected.? I thought the following comments from a close friend of mine might be of interest. ? "This winter has broken the record book—both in long term low temps (single digits every night; high in the upper teens daytime) AND in amounts of snow. ?June Lake gets 5-7 feet in a normal winter. ?That leaves a post storm settling of 3-4 feet November-April. ?Currently [written February 28th, before the storms of the last two weeks hit] we have had a little over 16 feet here in town, settling down to 13 feet." ? "And now the most important thing: ?YES…Sierra water crossings this summer!! ?It gets real crazy in the back-country when we’ve had 200%+ winters. ?Spring runoff will not subside until after July 4th. ?A lot of the snow pack is not going to melt…and crossing inlet/outlets is EXTREMELY dangerous. ?I’ve recovered a lot of dead bodies of mountaineers/backpackers who punched through the snow into the creeks/streams at flood stage—swept away downstream under ice…then drowned. ?A couple of thoughts: ?Change dates…depart in mid-August if your schedule allows. ?? Outlets/inlets more defined by then. ?Also, many folks get off-route/lost due to trails being covered by snow (particularly when crossing a high pass). ?If you don’t have a GPS with recharge solar panel, you must have paper topo maps and compass (so you can plot/triangulate position), and know how to use them. ?If we know where we are, we know the direction to head toward (applicable to both route finding and our spiritual lives!)." |
GPS / Satellites / Topo Maps & Compass
A friend of mine has been on the Search & Rescue Team in Mono County for many years.? We've been discussing the record snow levels this year, which got into a conversation about navigation in the Sierra.? Thought this little bit of "history" would be of interest to the group: ? Another quick story: ?All SAR [Search And Rescue] candidates are required to be competent in Map and Compass Navigation. ?When out in the field on operations, periodic “well-fair checks” by radio are conducted by Rescue Base with each team. Part of the well-fair check response is to report an approximate location of your team. ?The Team field leader always had a topo map tucked in his/her radio chest harness. ?It would sound like this: “Rescue Base, Team 2 OK, located 1/4 inch North of the ‘R’ in ‘Reds Meadow’” (Rescue Base would have a topo map of the search zone and place a “2” ?at 1/4 inch above the R in Reds Meadow on their map). ? GPS for civilian government agencies was made available in 1990. ?As a team, we had two early GPS hand-held Lowrance units we slowly integrated into operations. ?When Rescue Base would radio your Team for well-fair check, you’d report your location by reading the UTC# on the GPS (which translates into longitude and latitude). ?Later in 1990 we were in the field on a search when Rescue Base started doing well-checks and both GPS devices could not acquire satellite signals.? The teams in the field quickly adjusted back to using the topo map method to report their locations…no big deal, but perplexing. ?We found our overdue subject (who was ok) and all teams began to return to Rescue Base. ?When we all got back to RB, we started to talk about the GPS issue while standing around re-hydrating and snacking. ?All of a sudden our radios go off with the Sheriff “Tone” (indicating an officer safety issue), “Attention all Mono County units…all Mono County units…the United States has invaded Kuwait…repeat, the US has invaded Kuwait…all units acknowledge.” ?We all looked at each other…not shocked given the US military build-up to push Saddam out of Kuwait.? Each Sheriff deputy in the field began to acknowledge the alert from dispatch, including the SAR coordinator hanging out with us at Rescue Base. ?Suddenly it hit us - the reason we couldn’t acquire GPS satellites is because the US military turned off the civilian frequencies which, we learned later, were being used by our adversaries in Kuwait in their weapon guidance systems!. ?The other thing we learned about hand-held GPS devices is that the rechargeable batteries could not handle the cold of winter…they only last about 60 minutes.? (Today's units are much better). ?So, back to the importance of Map and Compass Navigation skills! ? |
Re: off-line information - satellite stuff
I hace noticed delay in inReach messaging. In fact I know just the places where it would be repeatedly delayed … or at least it happen that way .

Re: off-line information - satellite stuff
The Orbit app can be downloaded free from the Apple App store. Today is was listed 17th when I searched using "Orbit." Its icon looks like a blue basketball with a single black eye near the top.

Orbit was updated in 2022. I had previously emailed the author, noting that many Iridium satellites do not seem to appear in the app. Turns out that Iridium replaced its satellites in the 2017-2022 time period, which might explain this issue. Hopefully it accurately displays the current Iridium satellites. I use Orbit to set a reasonable expectation of when my "sent" inReach message should transmit and give me the "sent" tone. It displays Iridium satellites "visible" in the sky to you, based on where you are located. Sometimes my "sent" tone is delayed, so it's reassuring to know what the Iridium positions are (as opposed to a faulty inReach). In terrain with steep hills, sometimes my messages have not been sent and responded to for 45 minutes, which can get a little nerve wracking. Regarding Iridium flares: I loved those, too, using the HeavensAbove app. But they were a feature of the old Iridium satellites, and are not generated by the new ones. Wikipedia has a great explanation of them under "Iridium satellite constellation." Mike Sherman On 03/13/2023 9:05 PM Karina Bezkrovnaia via groups.io <kbezkrovnaia@...> wrote: |

Re: off-line information - satellite stuff
Iridium is the network we use with?Garmin inReach. And BTW, the US military, too. You can be sue it is operational, and will be a long time ;)

Re: off-line information - satellite stuff
My understanding is that the Iridium flares went away as their older satellites were replaced with newer ones that lacked the reflective surfaces that caused the flares. The Iridium network still is up there and functioning.?

off-line information - satellite stuff
FYI,
There is a neat app I like to play with while out and about. It is called heavensabove. It is not religious. It grabs satellite data so that one can look up and see what objects are flying overhead in space. The web site is heavens-above.com. Been using this for over 15 years. Neat to get ISS passings, Tiangong passing and other stuff. They use to have Iridium satellite flare information, but that constellation is not up anymore. This works world wide and the timing updates based on ones position; though hiking does not change position by that much. -- Two Dogs |
Re: Garmin inReach and weather apps
开云体育I did put in a request about the off-line access. I am waiting
for their response. I did not believe they had off-line weather.
If they did, I am asking for history data to be retrieved. Five
day forecasts are pretty accurate. Things start to get fuzzy
beyond that period. I will post back how they respond. Two Dogs On 3/13/2023 11:36, Karina Bezkrovnaia

Re: Garmin inReach and weather apps
Can you point to something on the OpenSnow/OpenSummit that claims you can get forecast data while offline? I can't find anything like that.? The only reference to "Offline" access is the ability to , along with your phone's GPS to pinpoint your location on the map. |

Re: Garmin inReach and weather apps
开云体育I agree, for up-to-date weather, one must have some type of
electronic contact with the world. The OpenSummit/Snow grabs ten
days worth of information, though beyond 5 days things can change.
But it can give a great trend until next cell phone coverage. Just
not sure about opening the app and have it use the most recent
weather data to display. Two Dogs On 3/13/2023 06:08, Jeff McWilliams

Re: Garmin inReach and weather apps
Karina, I don't think ANY of the weather apps mentioned work "offline", i.e. with no cellular coverage.? See here:? Another one I found is OCENS SpotCast, which is not free.? Never tried it.? The responses seem difficult to interpret in my opinion. |
