Location Aware Systems Location Aware Systems and Location Based Services (LBS) encompass a wide range of technologies in a broad range of applications from the professional to personal domains. Roke has capabilities in a wide range of enabling technologies for positioning and navigation together with communications and networks:
  • GNSS
  • Search and Rescue
  • Mobile location technologies
  • RFID
  • Zigbee
  • Direction Finding
  • eLoran
  • Inertial navigation (INS)
  • Acoustic Location
Increasingly positioning and navigation are not used in standalone applications but in hybrid systems that use Sensor and Data Fusion to enable an optimal solution based on an understanding of the capabilities of the various technologies.
Network time transfer Roke developed a caesium atomic clock based time transfer system for a multilateration system on which our network time transfer technology is built. Sub-nanosecond time synchronisation across a wide area system is achieved using GPS common view time transfer techniques with lower cost rubidium frequency standards. Use of other methods of disseminating time, or low cost oven controlled crystals is possible.
Ultra Wideband UWB has a broad potential applicability in short range radar, ranging, positioning, image processing, and communications. Roke has been active in the field of impulse radar since 1972 and is currently active in current UWB research.

Roke can provide both product solutions and consultancy for your positioning, tracking and timing requirements: including analysis and system design, module and algorithm design.
