This is literally the coolest thing we as a species achieved that doesn't serve self-preservation purposes.
Space-based businesses are hoping to grandfather themselves in once laws are established about the use of space, and betting that by then whatever service they offer will be seen as indispensable.
In the decade before that (so 2006-2015) we had four accidental collisions and two anti-satellite tests (China and US)
Those are not frequent events. And if you attribute any statistical significance to them, it seems we are getting much better at avoiding collisions
There are other reasons we don’t currently experience major problems with collisions in space, and why airplanes sometimes do, but it is not this.
Here's some math:
Average Earth diameter: 12742kms + 10km Average airplane surface area = 500m2 12752^2*pi = 510,865,389km2 Surface flight/plane = 1021730 planes
Starlink orbit height = ~500km Surface at orbit = ~551,712,377 so ~8% increase (which is non-negligible) Average Starlink satellite surface area = ~7m2 Surface LEO/satelite = 78816053 satellites (77x compared to airplanes)
Daily flights 50k-100k. Total number of satellites <20k.
And this is only for Starlink LEO. If you go for higher orbits the surface grows substantially. Also satellites have predictable paths, altitudes, airplanes maneuver and turn, gain altitude/lose altitude. They gather around points (airfields) etc...
Conversely:
> Daily flights 50k-100k. Total number of satellites <20k.
Those 20k satellites orbit roughly every 95 minutes, so they're doing ~15 orbits per day, and even the longest flights from conventional aircraft are about half that distance, so by distance each satellite in LEO is doing strictly more than the equivalent of 30 flights per day each.
Research I'm doing for a blog post has shown me that the exact position of a satellite is surprisingly variable compared to what you'd reasonably expect from a "Newtonian spherical Earth with a perfect vacuum" approximation of the orbits, enough so that it makes sense to treat 1 km as the "collision avoidance manoeuvres needed" threshold.
I've also seen reports that, as the satellites become overburdened, speeds are pretty variable. Again, not saying it's a net negative, but I just don't think there are "huge advantages" to Starlink.
I’m thinking buying a camper van, and just travel through the world. Except I need internet, everywhere.
There are no such options. Starlink is the best, but there are two main problems with it:
- In the countries where it would be the most useful, it’s not allowed to be used (Garmin has the same problem with their Fenix 8 Pro, their availability maps are a joke) - You need to go back to your “home” country every other month (there is a non legal, thus risky, option to circumvent this for now)
So, that huge advantage is not here yet at all.
- data throughput orders of magnitude higher,
- the ability to use smaller and more portable antennas (e.g. ~100 Mbps with something the size of a textbook, currently ~2 Mbps and soon ~10s Mbps with your normal mobile phone),
- order of magnitude lower latency compared to GSO satellites.
Other constellations like Iridium dedicate large portions to use by government(s?), too, but simply do not have the throughput or total bandwidth that Starlink does. Your speeds there, on the expensive business plans that offer it, are measured in the low Kbps.
In Guam it means 10Gbps without Fiber.
'Secret military documents from clandestine forums between Russia and China have revealed a possible joint strategic plan to disable Elon Musk’s Starlink satellite network alongside a deep weapons development partnership spanning hypersonic missile defense and autonomous drones, The Insider reported on July 9.'

linear error≈Rtan(Δθ)≈RΔθ
Here linear error is the error in position, R is the distance from the observer to the target and θ is the angle error. You would need incredibly good optics and resolution to minimise angular error and thus linear error.
There is also the problem that as R shrinks, speed increases relative to you.
This contrasts greatly with actual GNSS – the whole point of GPS and the others is that you don't need to determine those angles. The only thing you need to determine is the signal delay (i.e. distance) from a few satellites. That's a lot more convenient.
Cool app though, have it on a large screen at our work to visualise the constellations we work with as a fun screensaver type thing.
I wonder if there are other satellites not included in this dataset, or if I should search way further from the location on the map
the anti collision manuevers are hard as well.
orbits are simpler at lower lattitudes where you run a trajectory, close to parallel to the equator.
In order to cover those northern/southern extremes, more expensive high inclination orbits are required (in the US these are launched from California). They are more expensive because you’re no longer getting the rotational velocity of the earth for free in your orbital velocity.
So for a LEO constellation you want to minimize the launches to high inclinations and keep the bulk in those juicy easterly ones.
But the sad reality many of the hardware is Elon Musk's ejaculation stains, polluting the skies.
click on a dot and it will show up on a list to top left, click on an item in that list and you get a flyout menu to the top left with a bunch of data regarding the satellite.
The Starlink v2 is 100ft on it's longest dimension. This means that the actual size of the satellite relative to the dot is on the same order of magnitude (.6%) as the dot is to the size of the US when it takes up my entire screen.
A Starlink satellite is roughly 6 m (20 ft) wide without its solar panels. This means a one-pixel satellite marker is shown at roughly 1,000 times its true size. So even if this image already looks extremely crowded, the dots are still massively exaggerated. Visually, there would be roughly another factor of 1,000 before the satellites themselves were shown at their true scale—although this does not mean that orbit could easily accommodate 1,000 times more satellites but I guess there is still some space in space.
