Sure, but it seems to me like the Starlink path will still be longer in almost all cases unless you're incredibly lucky and the satellites line up exactly along the path for a few seconds. And Starlink could have additional delays related to routing and possibly TDMA. What kind of latency issues need to be considered with shortwave?
- alexpil 6y agoa single orbital plane at 53' contains 7028 satellites (out of 40k total, but let's take one orbital plane) basic math, "satellite density" or "average distance between satellites" if they were just at random position is ~200km (napkin math, might be off).
- sargun 6y agoSome folks wrote a paper based on the proposed constellation: https://dl.acm.org/doi/10.1145/3286062.3286075 https://dl.acm.org/doi/10.1145/3286062.3286075 The paper actually talks about trading: > Already there are new private microwave relay links between New York and Chicago[11], London and Frankfurt[1], and London and Paris. These links have relatively low capacity compared to fiber, but are of high enough value to the finance industry to be worth building new low latency links In their paper, they say NYC / LON RTT will be between 58 and 66 ms -- this isn't much better than fiber. On the other hand, London to Joburg -- starlink has an advantage.
