Geotab® GO9® Device Technical Specifications

Expandable Telematics Device

Geotab’s GO9 telematics device is the most powerful yet. The GO9 offers a 32-bit processor, 4x more memory and 5x more RAM than the GO8. Similar to the GO8®, the GO9 offers state-of-the-art GPS technology, g-force monitoring, GEOTAB IOXTM expandability, engine and battery health assessments, and communication on the LTE network*.


Using Geotab’s patented tracking algorithm, the GO9 accurately recreates vehicle trips and analyzes incidents. The GO9 also offers in-vehicle alerts to instantly notify drivers of infractions and — with hardware Add-Ons — provides live coaching for driver’s on-road performance. The GO9 does not require a dash-mounted antenna or any wire splicing.

Top Features

  • Easy installation

  • Additional native support for more vehicle protocols
  • End-to-end cybersecurity


Geotab platform security is designed for end-to-end protection of your data.

Key implementations include:

  • GO device and network interfaces use authentication, encryption, and message integrity verification.
  • GO devices are individualized. Each device uses a unique ID and non-static security key — making it difficult to fake a device’s identity.
  • Over-the-air updates use digitally-signed firmware to verify that updates come from a trusted source.
  • Geotab uses independent third-party experts to validate the platform from end to end.
  • FIPS 140-2 validated by NIST (certificate #3371)
