All-optical switching could greatly reduce complexity and power
consumption on the satellites at the cost of flexibility. Up to 44
satellites in an orbital plane would use individual wavelengths which
would be passed on transparently down the daisy chain and only
satellites in range of gateways
Why not acquire the time directly from by the satellite terminal and run local
NTP servers instead of syncing via the Internet? LEO satellite terminals always
have onboard GNSS antennas for geolocation which is necessary to find the
satellites, so integrating a local GNSS-disciplined Stratum-1 N
Hi Hesham,
You do not acquire the time from a LEO satellite but directly from the GPS
satellites which carry an atomic clock on board.
I'd not be aware of any LEO providing a GNSS signal but Xona plan such system
(although not carrying proper atomic clocks but probably chip-sized atomic
clocks
