The antenna supplied with Sentinel has a 20m cable, which equates to a delay of 100ns.
Setting the Sentinel antenna delay while GNSS is connected could cause a step change in the 1PPS phase input to the internal Rubidium oscillator and will require the Sentinel to be re-disciplined for a period of 6 hours. To avoid this the following procedure should be followed.
