Built-in processor for custom

The ReACT and ReACT+ (Receiver Antenna Compact Technology) Smart Antenna is a compact, rugged enclosure including a high precision GPS and GNSS Receiver and antenna.

ReACT and ReACT+ can be fitted with a selection of GNSS receivers and therefore offers a cost effective and flexible solution to your requirements. It offers the latest technology for precision position, velocities, heading and attitude by GNSS-alone or inertial navigation.

The ReACT is an alternative to the now obsolete NovAtel’s SMART-V1 and Smart-V1G. It boasts similar size and offers comparable connectivity and mounting options.


ReACT and ReACT+ have been qualification tested against a strict set of standards to ensure that the system can operate in harsh environments. The full list is found on the back of the datasheet. They are compliant with requirements for military wheeled and tracked vehicles. Corrosion resistance in salt water environments has been achieved.


ReACT can include an optional module enabling custom application enhancement for bespoke applications. We provide a range of “EDGE-WARE” firmware modules for additional I/O, data output and functionality including CAN frame configuration, enhanced inertial operation and attitude determination through a linked antenna network. ReACT with EDGE-COM masters the meaning of low-latency data, e.g. timed position data is ready for use up to 0.15 seconds earlier at 4800 baud  than standard GNSS receivers.


Our product design allows for the ReACT+ to be adapted to meet bespoke requirements and applications in a short timescale. Inbuilt firmware enables modification to support custom data formats.


  • 555 Channels with multi-constellation tracking (GPS, GLONASS, BEIDOU, GALILEO, SBAS, L-BAND)
  • Dual-frequency and multi-constellation tracking increases position reliability and mitigates ionospheric effects.
  • Global 4cm accuracy with Terrastar
  • Extend RTK accuracy in correction outages of up to 20 minutes with RTK AssistTM
  • Consistent and smooth pass to pass applications with GLIDE technology
  • INS Ready: pair with a range of IMU options to enable tightly coupled GNSS/INS


The ReACT is available in a range of model variants

Please note: a custom colour and branding service is available to make your ReACT completely bespoke to your needs
