Starlink decoded for use as GPS alternative – without Elon Musk's help Researchers rebuffed by SpaceX have taken matters into their own hands and reverse-engineered Starlink's satellite signal for potential use as a GPS alternative. University of Texas Austin professor Todd Humphreys and his team claim in a non-peer reviewed paper that they've managed to decode Starlink downlink signals in the …
step 1 decode the signals, using existing hardware and/or SDR (Software Defined Radio)
step 2 create your own initial bulky hardware to decode the signals.
step 3 create and sell tiny self contained modules with power and antenna inputs that output standard NMEA formatted data to a UART (serial port).
30 meters accuracy or precision for companies with military contracts, used as either a backup subsystem or as an extra data source for a Kalman filter, would sell extremely well. Simply because it is on a totally different frequency band.
After following the tracks for two days, we can see the Bad Guy(tm)
Nah, after logging the data points for Bad Guys1-13 for 2 days, plot them on a GIS. You can then display their tracks, where they intersect, and arrange a cease & de-exist notice to that location. Probably why HQs and supply dumps have an unfortunate habit of going from hub site to bomb site.
Musk PROFITEERS 400 Million dollars for receivers in Ukraine paid by volunteers and users while he "Donated" 3000 units one time.
He egotistically threatened to cut off Paid Subscription service and asked DoD to gift him almost 900 million fot a Paid Service!
Billionaires and MultiNationalCompanies need to be taxed at 75% gross and anyone below 10% of what the CEO is making gets compensated to meet the company mean wage. Rest held until the company or top mgmt eventually messes up and then boom dissolve and payout all impacted.
Everything goes public domain after 50 years. Billionaires dont get to trickledickdown or hold economy hostage.
This is the Nukeclear option. only way to be sure.
You obviously haven't been paying attention. Let me explain about this "free market" thing once more.
Back in the Good Old Days capitalism was 'regulated', the government regulated the market for essentials like energy and communications because they were a common good. However, regulation and oversight (as you've been taught from the cradle) is really bad. The only kind of dynamic economy capable of delivering prosperity for all is a free market, and by that we mean free from all government interference. In fact the modern capitalist is quite libertarian in their desire to shrink the state to the smallest size commensurate with keeping order among the Great Unwashed.
This why your energy bills are skyrocketing. Its not that there is any more or any less energy to sell but rather that a shortage creates a price spike in the commodity trading markets which means good times for the traders and investors. The fat that this money is coming out of your rapidly thinning budget is irrelevant because if the government was to step in and try to regulate the market then there would be a huge price crash, a run on the currency and so on. Markets don't just rule, they dominate.
Just focusing on an individual like Musk misses the point. Anyway, if we tried that SpaceX would tie us up in the courts for years and probably jack the price of ISS access. It would also send a negative signal to other corporations with some likely fallout.
Long story short -- this is the bed we made by electing successive governments who favored modernization and reform. We turned our backs on those stuck in the mid types who said it will all end in tears (it did before but obviously past experience is absolutely no indication of future performance because we've got computers, smartphones and other wonderful stuff). Enjoy.
"Billionaires and MultiNationalCompanies need to be taxed at 75% gross" there would be no Starlink then, no SpaceX, no Tesla and probably no electric cars. They'd also be no smartphones, no Google and no Covid vaccine.
Musk has reinvested all of his money. His wealth isn't mainly cash, it's tied to the value of Tesla and SpaceX shares, if he sold them, they'd instantly be worth less.
Ah, you've fallen for that scam too. Don't worry, lots of people do.
His horses, houses, cars, spaceship, etc are all on debt, or simply owned by his companies. Of course he's got complete control over them, but yes, he's left most of his $billions invested in his company(ies) - where would he even keep a pile of a $billion in sacks of notes, even if he wanted to?
Taxing him 75% of any take-home over the first billion in any year would have almost no effect in 9 out of ten years!
"Taxing him 75% of any take-home over the first billion in any year would have almost no effect in 9 out of ten years!"
Yeahbut, the OP was talking about taxing 75% of gross, not net. And he wanted that tax on the billionaires and the multinationals. That would bring in enormous amounts of tax the first year and then nothing in subsequent years since they'd close up shop.
I may be wrong of course because the OP failed to mention what he meant by "gross". Gross turnover? Gross income? Gross profit? 144? Just being horrible and icky?
I think Starlink should have their receivers doing radio astronomy during idle time. Like that black hole that burped after eating a star, that was only detected by chance. Instead you could use tens of thousands of little dishes to listen for like, an hour at a time to lots and lots of targets.
That:
"He said SpaceX could publish a clock correction for each satellite - something that is currently done for GPS - which would reduce errors to under one meter"
Is due to relativity. Because the satellites are moving so fast (relative to you), you need the correction to account for the differences in time between you and the satellite!
This stuff fascinates me :-)
…moralising by the journo.
> We cannot afford any distractions
IOW, SpaceX did not prevent the researchers from doing their research on their own dime. They just did not allocate any resources to it.
We're not talking about sending a cease and desist or opposing the research in any way. They just decided that their contribution was going to be to stay in business.
