Chronos Technology is recognised as a leading authority in GNSS. We are a specialist supplier and installer of GNSS (GPS, GLONASS, Galileo and BeiDou) simulators, repeaters, receivers, antennas and infrastructure. Chronos is also a world leader in GNSS vulnerabilities, jamming and interference detection and location technology, and a supplier of underground GNSS coverage solutions.
Working with industry leading suppliers we have formed long standing relationships with our customers; supplying a variety of sectors including Police, Royal Air Force, Ministry of Defence, Fire & Rescue, Manufacturing, Aerospace, UAV, Automotive, Marine and Telecoms.
In addition to the following products, see gps-world.uk website for our full range of GNSS solutions and accessories.
Most modern timing systems rely on signals from Global Navigation Satellite Systems (GNSS), such as GPS or GLONASS, for accuracy. Moreover, many other industrial and government applications also rely on these signals for positioning. Yet GNSS signals are low-power by design, making them vulnerable to jamming and spoofing.
That means you need effective detection and contingency plans to prevent operational disruption.
Indeed, deliberate cyber-attacks on critical strategic infrastructure are on the rise – whether it’s malevolent spoofing of GNSS at the state level, or signal jamming that’s often simply caused by human error.
A sophisticated spoofing attack can gradually introduce small and subtle timing errors into your networks – beating detection algorithms and creating potential points of failure in your systems. Sustained signal jams, while easier to detect, can also cause problems if there’s a lack of resilience in your network.
Critical Applications
GPS and cyber security is especially important if you’re responsible for:
Critical national infrastructure such as power, broadcast, finance, telecoms or government systems.
Industrial applications where timing and sync distortion could lead to lengthy or expensive outages.
Infrastructure where risk to life increases from failure.
The Chronos difference
You can gain access to all the tools and expertise you need to prevent GNSS disruption, and to make your operations as resilient as possible.
Applications
Chronos can design and deliver bespoke GNSS over fibre systems for effective RF signal distribution in demanding and harsh environments. Providing higher noise immunity and therefore less interference than copper solutions, RF over fibre is an ideal secure solution for government and defence buildings (including ultra-secure ‘Dark’ areas within buildings, anechoic chambers etc) or in DAS applications, and hosting centres.
Chronos can design and install resilient duplicated GNSS over fibre distribution systems which can be split across multiple floors/locations with minimum attenuation and signal degradation providing RF signal distribution over a secure network. Chronos can also enable GNSS in individual rooms by installing fixed GPS repeaters that allow you to test applications that require a GNSS signal over the air.
RF over fibre is ideal for multiple base stations and in instances where there is limited roof space for GPS antennas as the solution allows the possibility of using one antenna with the signal converted to light and then optically split to multiple locations.
Moreover, you can also rethink your operational infrastructure, using GPS repeater and other technologies to provide accurate satellite signals indoors and underground.
Septentrio reference receivers are an industry benchmark providing continuous measurement output with a remarkably low number of data-gaps, which affect the quality of your correction service or Earth monitoring continuity. They offer interference robustness with Advanced Interference Mitigation (AIM+) ensuring reliable operation despite GNSS jamming or spoofing. An open interface ensures compatibility with other systems with standard data format like RTCM, MSM, RINEX and BINEX.
Septentrio is dedicated to keeping its reference receiver firmware up to date, with the following latest features:
• Tracking of BeiDou B1C and B2a signals, for improved RTK service
• BeiDou extended constellation (PRNs C38 to C63), tracking BeiDou B2b signal
• TLS (Transport Layer Security) on NTRIP connections
With the widespread use and high reliance on GNSS / GPS comes vulnerability to outages caused by jamming, interference and spoofing. Chronos Technology’s GPS Jammer Detectors are ideal for the detection and location of commercially available GPS jammers hidden in vehicles. The handheld, battery operated devices are designed to detect and quickly locate the presence of jamming signals from commercially available GPS jammers or too much power or interference broadcast in the GPS (L1) band.
GPS coverage has become a fundamental tool for emergency services, significantly improving their intervention capabilities. Yet, when entering an underground area such as a subway station or tunnel, they lose that advantage as the GPS signal is lost. Syntony’s SubWAVE product extends 100% GPS coverage to underground areas such as tunnels, stations, parking, bus stations & airports, thus enabling localisation of any equipment or person with a standard GPS receiver (smartphone, TETRA radio or future Emergency Services Network handsets).
