The Q40 Global Navigation Satellite System (GNSS) receiver developed by QinetiQ, is a next-generation GNSS navigation receivers are for users for whom positioning, navigation and timing (PNT) is mission critical. The Q40 can be used in governmental, military, critical national infrastructure, industrial and demanding commercial applications.
The advanced design provides robust PNT even in contested and degraded signal environments with low power consumption. High-assurance PNT software provides Receiver Autonomous Integrity Monitoring, constellation cross-checks and signal management to ensure a high level of availability and accuracy.
Through new, advanced digital signal and navigation processing, it provides market leading mitigation against a wide range of interference, jamming, spoofing and cyber threats.

Missed our recent session of resilient GNSS? You can now access the recording and explore how next-generation technologies are delivering assured positioning, navigation and timing (PNT) for weapons guidance – even in contested environments.
The Q40 family, manufactured in the UK, consists of two variants, both following Secure by Design principles:
Q40 replaces the Q20 GPS receiver, which QinetiQ has successfully delivered over the last 20 years for industrial applications and defence systems.
The Q40 GB-GRAM card is a small-form-factor, multi-constellation, multi-frequency, open service GNSS receiver, fabricated as a compact, double-sided assembly with Commercial-off-the-Shelf (COTS) connectors to simplify integration into host equipment. At its core is the Q40 GNSS receiver, delivering high levels of robust and reliable PNT along with powerful mitigation against a wide range of interference, jamming, spoofing and cyber threats.
Multi-Constellation Open Service (MCOS) receiver with access to a number of constellations and frequency bands including GPS and Galileo that allows for PNT solution even with frequency band jammed.
Advanced anti-jamming and anti-spoofing that incorporates a number of unique algorithms and techniques that delivers a best-in-class performance in real operational environments.
Rapid Time to First Fix (TTFF) through the ability to provide very precise aiding inputs that allows for rapid PNT solutions from start up.
High dynamics with velocities of 8000m/s and accelerations of 100g that is unmatched by any open service and encrypted dynamic receivers.
Timing accuracy of <5ns that is best in class for COTS open service receivers.
A gun hardened receiver that is capable of dealing with tube launch set back of up to 25,000g. The hardware between the Q40 MicroPNT and Q40 MicroStrike is consistent.
Secure By Design principles were followed in the development and manufacture of the Q40 GNSS receiver, which included ensuring a sovereign supply chain.
Qualified to Military requirements which include temperature, shock / vibration and EMC standards which simplifies specification in programmes.
Optimised for Defence use through the requirements setting by MOD to the validation and verification all hardware and software releases within the programme.
