Critical Infrastructure Systems

The Challenge

Fail-safe positioning, navigation and timing solutions are needed for the development and protection of critical infrastructures in a variety of applications:


  • Communications: Precise time and frequency optimize bandwidth and reliability
  • Mobile: Tightly coupled positioning and navigation functions in any location
  • Power and Critical Utilities: Rely on time measurements in their delivery systems
  • Financial Services/Banking: Timing involved in every transaction from ATM to automated trade
  • Transportation:  Enhanced safety for manned, semi-autonomy and unmanned systems
  • Cyber Security:  Enabled through accurate timestamps of network activity 

Let's protect critical infrastructures together.

The more sophisticated our infrastructure, the more risks that need to be addressed. We can help. It starts with a discussion. We call it a fit assessment.


Collaborative Solutions

Spectracom has a long and rich history of collaborating with the public safety community to bring precision time and frequency to emergency response systems. This history, coupled with an organization that deeply values collaboration, is helping us solve issues across industries.

The Building Blocks

From our timing solutions that are an integral part of 9-1-1 and other public safety systems to our GPS signal generators and mobile PNT platforms, we have the building blocks to enable and enhance critical infrastructure systems.

Here are some examples:

Ingenuity at Work

  • A GPS Solution for Indoor Location

    An intelligent repeater system offers a cost-effective indoor positioning solution for GPS-denied environments

    This system allows for the use of standard GPS devices for seamless transition between live sky GPS and indoor or subterranean locations to calculate position within zones defined by the number of GPS simulators.

As video surveillance hardware becomes IP-based, systems are able to take advantage of the network to improve efficiency and performance. Time synchronization, in which all the clocks in cameras, recording equipment, and computers have the same time, is simple to implement on the network. It utilizes a standard protocol and a network appliance known as a time server. What’s more, the time server can be legally traceable to a time authority. The result is low-cost investment protection for the video system deployment.

Signals from Global Navigation Satellite Systems (GNSS), such as the Global Positioning System (GPS), are very weak and usually cannot be seen indoors or underground. A common method to overcome the problem of receiving GNSS signals indoors or underground is to use a GPS/GNSS repeater with an antenna located outdoors to receive the GNSS signals and an amplifier/antenna to re-transmit the signal indoors. This paper describes the technologies and methods for creating an intelligent repeater system including time synchronization at the nanosecond, microsecond, and millisecond levels, how each synchronization level affects the overall system and methods for achieving each, power level considerations including power level requirements between zones and how they affect transitions from one zone to another, data transfer and example system configurations. While GPS is primarily demonstrated and tested, the possibility for adding other GNSS constellations such as QZSS, BeiDou, Galileo, and GLONASS are also presented.
