“…From the Ublox Neo 6M GPS, a PPS signal output is available—a pulse with a frequency of 1 s. This signal is satellite-synchronized, resulting in precise timing accuracy. However, according to [ 34 ], this method is not sufficient for achieving synchronization in all measurements. In this sense, there are instances of exact synchronization and others that are not synchronized due to the nature of microcontrollers.…”

“…Specifically, the Analog-to-Digital Converter (ADC) triggered by the local oscillator is reset at each rising edge of the Pulse Per Second (PPS) signal to achieve synchronization once every second (AbdelRaheem et al, 2022;Pardo-Zamora et al, 2021;Monteiro et al, 2016). However, discrepancies between the PPS signal and the local oscillator's clock domain may result in variations in the actual sampling interval compared to the ideal interval, leading to what is known as Sampling Time Error (STE) (Yao et al, 2018;AbdelRaheem et al, 2022), as illustrated in Figure 1.…”

“…This technique works by aligning the clocks in analog-to-digital converters (ADCs) with a universal time reference. Most often, this reference comes from Pulse Per Second (PPS) signals provided by Global Positioning Systems (GPS) (Pardo-Zamora et al, 2020), the IEEE 1588 Precision Time Protocol (PTP) (Ahmad Khan and Hayes, 2020), or the Network Time Protocol (NTP) (Park H. et al, 2021). Recently, synchronization signals from 5G networks have also been used (Xiao et al, 2021).…”
