SKYLAB SKG172TC

The SKYLAB SKG172TC is a single-frequency, multi-constellation GNSS timing module supporting five satellite systems in the L1 band. It combines positioning, timing and autonomous integrity monitoring with 1PPS and PVT outputs for power systems, base stations, personal timing devices and other high-precision timing applications.

Applications: High-precision timing for power systems and base stations, personal timing devices, and other high-precision timing applications
Supply voltage: VCC: 2.85 ~ 3.45 V
Dimensions: 17.0 x 22.4 x 2.4 mm

Product overview

The SKYLAB SKG172TC receives L1-band signals from BDS, GPS, GLONASS, Galileo and QZSS, combining multi-constellation positioning and timing with autonomous integrity monitoring. It provides a one-pulse-per-second timing signal and PVT information for applications including power-system timing, base-station timing and personal timing devices. The module measures 17.0 x 22.4 x 2.4 mm, operates from a VCC supply of 2.85 ~ 3.45V and features a UART interface.

The 1PPS output offers timing accuracy of less than 10ns at 1-Sigma, with an adjustable pulse width defaulting to 100ms. Its rising edge defines the synchronization point and has a rise time below 5ns. A delay-setting command allows phase adjustment. Once timing is valid, the first TOD information character is separated from the 1PPS rising edge by 5ms–15ms. Antenna monitoring provides short-circuit, open-circuit and connection indicators, alongside a voltage supply for an active antenna.
