Richard, or Martin, or anyone, What's the latest on how GLONASS handles leap seconds? I remember years ago receivers (or the SV itself) reset their timescale across the leap event -- because they use UTC(SU)+3h (Moscow local time) as their system time and not a leap-less, timezone-free timescale like GPS system time.
Multi-GNSS receivers might be able ride through this with some heuristic so the question is more what really happens underneath, or to GLONASS-only receivers these days?
