Decreased vertical precision is an artefact of measurement geometry more than e.g. number of frequencies.
Horizontal position has the benefit of having satellites at almost all azimuths. But the vertical position estimate only gets satellites from at most half of possible elevations (above the horizon).
Let them buy all the defensive weapons they can afford, Iron Dome, etc.
I think US gives them the weapons otherwise, they don't even buy them? No more.
It is insanity to let them just kill whomever they want whenever they want as many as they want
Israel has a right to exist but not kill thousands of innocent people
They also have universal healthcare while US never will because we've spent $21 Trillion since 9/11 on militarization, adding another trillion this year and now have to replace all the tomahawks etc
They're import-reliant. They don't make steel, don't make aluminum, don't have a large chemicals industry, etc. They're very vulnerable to sanctions and trade restrictions.
It frames themselves as under attack, which thereby gives themselves moral justification to attack, and when those attacked attack back they fulfill their justification, and the circle of violence and death perpetuates.
Countries don't have any "right to exist", this very term is thought terminating propaganda created by Israel. Israel does not have a right to exist, countries either are, or aren't. People have a right to live.
And as it stands, Israel is a terrorist nation commiting war crimes and a genocide daily.
"Defensive" weapons also do not exist. If you give Israel weapons, or sell them weapons, you are complicit in their actions.
What he's saying is that Israel itself doesn't have a right to exist based on international law, but its people - be it Israelis or Palestinians have a right to live.
Palestinians are already being hurt by israelis, Palestinian land was stolen by israelis, Palestinians are being put in open air concentration camps by israelis, humiliated, abused, starved, killed, hunted down, so excuse me for not caring much about your "problematic statement". Countries have no legitimacy to exist, however they do have history: Israel as a state is a lot more illegitimate in its existence than a Palestinian state, and considering it is the state committing a genocide right now and it doesn't seem to be sticking: Israel doesn't have a right to exist, and the state that is right now Israel is also a terrorist, genocidal one.
Israelis forced themselves in stolen, colonised land, settled with violence, used the weapons of the western colonizers against local populations and actively worked to destroy every attempt at peaceful cooperation that there has ever been, member of Israel's current government having actively called for the murder of Rabin and might very well be directly involved in it. Israel has made it so that the situation effectively ends with either Israelis dying, or the whole region dying.
>Uses the age old "hurr actually the name Palestine was Judea"
Ok Mossad. Israel attacked Palestine, Lebanon, Iran, Egypt, Jordan, is a terrorist country and doesn't have the right to exist. Israel is the one killing Palestinians and Lebanese citizens right now.
(PS: you know people see through when you post 50 prepared paragraphs of Zionist propaganda, right?)
if I remember correctly the space shuttle had four computers that all did the same processing and a fifth that decided what was the correct answer if they all didn't match or some went down
can't find a wikipedia article on it but the times had an article in 1981
You do need access to a large telescope (at least 1.2m based on the wiki article), a sensitive detector (is photomultiplier tube sensitive enough??) and most importantly, access to your local laser clearinghouse so you don't accidentally shoot an airplane, blind the pilot and got arrested, or a satellite and start a war (if you believe some guy on quora). Probably the last part is the hardest thing for an amateur
What a nice vanilla view of the world. It's way to simple as an answer and lacking links to reality.
If not before but with high school kids will need access to a computer and also the internet in many schools and countries.
I get that parents are responsible but parents have limited resources. Even the best parenthood will not keep kids from wanting to engage with peers. Even the best filter or block by parents will not cover the www and their millions of websites and services.
Should society help the child, by making it more difficult for them to access harmful material, in the same way we age verify alcohol?
What if the parent is responsible, but finds themselves in a situation where they don't have the time/ability to either educate or set up robust controls? Should we make their responsibilities easier?
Instead of controlling the children, we should control the source. Perhaps we should ban harmful content from the internet. Not the government. But we, as users, need content to be reviewed by moderators. People should decide what is harmful. I’m sure we all know what is harmful, not just for children. Psychology shows us what goes on in an adult’s brain, it is exactly the same as what goes on in a child’s brain.
Before Youtube and Wikipedia there used to be a great website I liked to read about Philo Farnsworth but cannot remember the name of it for the life of me now
a 100 meter tall spaceship nearly 6 million pounds carrying nearly a million gallons of fuel for nearly 10 million pounds of thrust for JUST eight minutes
all that to escape Earth's mighty gravity well
pretty freaking amazing to watch even at that distance
The event itself was a few years before my time, but after reading about it and eventually watching the historical news footage, the phrase "go at throttle up" also seared itself into my brain, and ever since I flinch when I hear it.
Same. I watched last night, UK time, and I couldn't shake the worrying feeling. I was relieved that they got into orbit. Now I can be a little bit excited until re-entry. That worries me for the same reason.
In the UK as a kid, when Challenger happened, our children's news programme reported it before the mainstream TV.
I think you could just ship generic robot dogs in a container and have local contractors straw-purchase firearms, 3d-print cradles, and combine them. None of the contractors would need to know what they were doing.
Watches that use GPS for altitude are terribly inaccurate
It is interesting to run the opensource GPSTEST app on a smartphone and watch the MSL "settle" over time but each sat seems to disagree

btw watches are now getting THREE multi-band L1+L5 GPS chipsets, should help things
quad-band GNSS coming soon too!
