Rob Jodrie & 1st Generation BITS

Rob Jodrie explores the beginnings of BITS technology known as 1st Generation BITS. It’s part of a larger presentation that includes 2nd and 3rd Generation BITS capabilities and benefits.

Rob Jodrie & 3RD Generation BITS

Rob Jodrie has been supporting Network Timing for over 20 years. In that time, he’s seen the 1st Generation BITS progress to the current and new iteration known as 3rd Generation BITS. In this video, Rob goes into detail on each generation and shows you how we evolved to today’s BITS clocks and their capabilities.

TimeProvider® 4100

TimeProvider® 4100 is a gateway clock, a new class of synchronization product that accepts multiple inputs from Global Navigation Satellite Systems (GNSS), Synchronous Ethernet (SynE), and 1588 PTP Grandmaster Clock and E1/T1 digital transmission links, and distributes timing flows to multiple end points such as base stations.

GPS Vulnerability Support With BlueSky GNSS Firewall

BlueSky GNSS Firewall protects deployed GNSS systems by providing a cost-effective overlay solution installed between existing GNSS antennas and GNSS systems. The BlueSky GNSS Firewall protects systems inside the firewall from untrusted sky-based signals outside the firewall.


The virtual Primary Reference Time Clock is a highly resilient timing architecture that reduces reliance on Global Navigation Satellite System (GNSS)-based timing signals.

Resilitent Timing Services for 5G Networks

GridTime™ 3000 GNSS

The GridTime™ 3000 GNSS time server is a software-enabled solution that provides enhanced levels of redundant, secure and resilient timing for power utility substations. It generates precise time and frequency signals to synchronize analog and digital communication systems within the substation.
