I am using the timepulse output of the EVA-M8M GNSS Receiver as a PLL reference for a PTP application. Ideally, when my antenna receives a heavily attenuated signal I'd like my receiver to stop outputting its timepulse immediately, or within a few seconds, so that my system can enter a holdover state until a proper link is reestablished. However, as it stands now when this attenuation event does occur my receiver continues to output for an uncertain amount of time (10-40 seconds) until it finally stops being supplied. What can be done to hasten the removal of this lingering timepulse?
I've searched through the M8 Receiver Description Protocol Spec(UBX-1300221) and I haven't found anything that directly tackles my issue. Any assistance here would be greatly appreciated
