GPS / GNSS / NavIC
NTP Time Server

VCL manufactures a wide range of NTP Time Servers with ITU-T G.811 Primary Reference Clock for precise time synchronization across critical infrastructure such as utilities, transport, airports, defense, ISPs, and secure private networks. These servers feature integrated multi-band GNSS receivers that lock to GPS/GNSS/NavIC satellites with anti-jamming and anti-spoofing protection. Unlike public NTP sources that expose networks to cyber threats, VCL’s GPS/GNSS-based Stratum 1 servers ensure secure, reliable, and isolated time synchronization for 3G/4G/5G providers and private organizations.
Positioning, Navigation, and Timing (PNT) are essential capabilities for critical infrastructure, including telecommunications, power utilities, and industrial automation. Accurate and reliable PNT data enables precise time synchronization, coordinated network operations, and dependable system performance. The VCL GNSS-based time synchronization solution delivers accurate timing from multi-constellation GNSS and maintains timing continuity through its internal OCXO oscillator during temporary loss of the GNSS signal, within the specified holdover performance.
