The need for accurate, reliable and precise position and time measurements is critical for successful military operations. GNSS technology is relied upon to provide:

  • Day and nighttime navigation of unfamiliar terrain
  • Search and rescue capabilities
  • Reconnaissance planning and map creation of hostile or unknown territory
  • Ground and aerial unmanned vehicle navigation
  • Guidance and system testing capabilities

The size and configuration flexibility of NovAtel’s GNSS product line allows us to meet a wide range of navigation requirements.


Selective Availability Anti Spoofing Module (SAASM):

When keyed, the OEM625S provides an RTK PPS solution by taking the raw measurements from an L-3 XFACTOR Selective Availability Anti Spoofing Module (SAASM) and applying them to NovAtel’s industry leading RTK algorithm. In the Standard Positioning Service (SPS) fallback mode, the OEM625S continues to provide centimetre-level accuracy by utilizing NovAtel’s dual-frequency civil GNSS positioning engine.


GPS Anti Jam Antenna (GAJT):

GAJT provides anti-jam performance comparable to much larger systems, but at a significantly lower cost. GAJT is a Commercial Off-the-Shelf (COTS) product, providing short order lead times and quick deployment. It easily integrates into new vehicle platforms or can be retrofitted with GPS receivers and vehicle navigation systems on existing and legacy military fleets.

Novatel GAJTTactical Grade Fiber Optic Gyro (INS):

Paired with NovAtel’s OEM6 receiver, the IMU-CPT offers a fully integrated, tightly coupled GNSS and IMU system delivering the most satellite observations and the most accurate, continuous position, velocity and attitude solution possible. Further, the IMU-CPT is comprised entirely of commercial components, greatly minimizing cross border difficulties encountered with traditional GNSS+INS systems.

Military, defence and government organisations are increasingly reliant on satellite systems for timing, navigation and positioning. Mission-critical systems must be able to provide required levels of accuracy, integrity, availability and continuity under all conditions—failure isn’t an option.

Developed over years of collaboration with governments and defence organisations, Spirent’s extensive simulation solutions enable systems developers to test mission-critical systems for resilience in the presence of a full range of possible threats and other factors that impact performance.

Spirent has been at the forefront of military testing for 25 years, working with military and defence organisations to test leading-edge systems in the areas of:

  • Adversarial interference—which simulates a wide range of interference waveforms and threat sources
  • Classified signals—to ensure conformance to SAASM, modernized GPS M-code and Galileo PRS systems—authorised users only
  • Adaptive and multi-antenna tests—used to assess adaptive antenna technology, as well as multi-antenna attitude and differential system testing
  • High dynamics tests—check support for spinning vehicles with high signal iteration rates
  • GPS/inertial navigation—tests the capabilities of common integrated avionics
  • Hardware-in-the-loop—tests real-time, high-data rate and low latency scenarios
  • Field verification tests—confirm correct operation using simulation or GNSS record & playback
  • Mission planning testing—creates representative operational scenarios using simulation or RPS
