My first response was "Sweet, Starlink in a mobile phone!" but this is just VoIP over the existing Starlink dish, which, while cool, is not a huge surprise. SpaceX has not shrunk their receiver into a mobile phone [yet]. As someone who frequently goes out of cell phone range, I would love to see something like SPOT or inReach over the Starlink network instead of Iridium, maybe they can bring the price of these services down a little bit more.
- crispycrafter2 6y agoOK, so my knee jerk reaction was that the wavelength that starlink use simply won't allow it. Practically the antenna needs to be at least 1/4 the size of your target wavelength [1] It seems though space ex are using vanilla Ka, Ku and E band frequency, which have wavelengths in the centi to millimeter range. It must be that we don't have enough devices yet to allow for seamless handover between sats, without ground based tracking antennas [1] https://physics.stackexchange.com/questions/315915/why-do-we https://physics.stackexchange.com/questions/315915/why-do-we...
- londons_explore 6y agoThey have a non-interference requirement for geostationary satellites using the same frequencies for uplink. That means they need fancy antennas to make sure there is a null all along the eqaitorial geostationary orbit line...
