Big Ben Time Server is a GPS/NTP time synchronization tool for Windows. It reads serial data output from GPS receivers, decodes $GPRMC and $GNRMC messages to obtain accurate UTC time, and corrects the PC BIOS or system clock. The page also offers NPL Anthorn MSF Time Signal Decoder Clock, which synchronizes Windows PC time via an MSF long-wave time signal receiver.
The product highlights GNSS Anti-Spoofing Technology and states that it was tested by the UK National Physical Laboratory in 2022, with certified test results available. It supports USB/serial GPS receivers and is suited to environments without a network time source or where a trusted local time source is required. The page mentions use cases across civil, military, land, sea, and air applications, as well as industrial sites—for example, providing an accurate time reference for Gas Plant SCADA & PLC control systems.
Supported systems are mainly Windows, including Vista/7/8/10, with other text mentioning XP, 7, and 10. The MSF decoder supports Windows 7, 8, 8.1, and 10. There is no visible information about Linux, macOS, containers, cloud deployment, or APIs/SDKs. The installation steps also require the K-Tron GPS ActiveX control and mention installing VLC Media Player, so the overall technology stack feels quite traditional.
Pricing is very straightforward: the page says the 30-day trial of Big Ben Time Server requires a £20 registration payment via PayPal, after which users contact the vendor by email to obtain a username and password. It also states that the price is £20 for both commercial and non-commercial use. The MSF decoder is likewise listed with a £20 trial registration via the same method. The upside is the low cost; the downside is that the process is manual and does not offer the instant onboarding typical of modern SaaS or developer tools.
The strengths are its low price, local operation, support for older Windows systems, compatibility with GPS/MSF hardware, and supporting NPL test and case-study materials. The weaknesses are its single-platform focus, dated documentation and registration experience, and lack of details around APIs, SDKs, SLAs, version updates, or enterprise support.
It is better suited to engineering users who need accurate local time synchronization on Windows, especially in industrial control, energy, laboratory, measurement equipment, and SCADA/PLC scenarios. It is less suitable for teams looking for cross-platform support, cloud-native deployment, automated operations, or developer APIs.
The page mentions having received inquiries from international companies in China, but it does not provide information on access from China, payment availability, or local support, so accessibility from China remains unclear. Payment is via PayPal, which domestic enterprise buyers may need to verify further. Comparable alternatives include commercial GPS time synchronization hardware, Galleon Systems products, Windows NTP synchronization solutions, and Meinberg NTP.
