When you have an PTP appliance with a GPS antenna, is it assumed the determined position is that of the antenna or the GPS circuitry decoding the signals inside the appliance? How far can a GPS antenna be remoted from the appliance?
Generally speaking, the maximum length of the coaxial connection between a GPS receiver and its antenna depends on the specifications of the receiver, antenna, coax cable, and coax connection systems. The latency between the antenna's actual position and the calculation of its position would need to be derived from the GPS system specifications. Since this latency is independent of PTP, it would need to be subtracted from the PTP time stamp of any GPS measurements. Hope this helps!
Do you know if this could work also on windows, or only on UNIX, please ? Could you get TX and RX timestamps on windows for GPTP ? (Only on intel network adapters, or could you do it on any other brand ?)

brief but very clear and concise. Thanks! It tooks few minutes to fresh up.
very useful.
@@acluster3411 thank you
