CW25-TIM GPS Timing Module

The CW25-TIM is a small size GPS OEM module that has been optimized for accurate timing applications. Leveraging Navsync’s core CW25 platform that utilizes 12288 correlators in the BB25 baseband processor to search for low-signal strength GPS signals, the CW25-TIM assumes a positional lock after initially acquiring satellites to optimize GPS timing accuracy.

Aside from low signal tracking, which is more applicable for GPS location rather than timing applications, the BB25’s algorithms also support quick Time To First Fix (TTFF), when ephemeris and almanac data is available and also in cold start environments. The low signal tracking capabilities have benefits within fixed timing applications by reducing the cost of installations by lessening the burden of high antenna mounts. GPS timing will degrade if the GPS antenna is entirely obscured or put indoors, but tracking will continue.

Equipment using a CW25-TIM can operate in installations without open-sky access and even some indoor environments. With a size of just over an inch square (25 x 27 mm) and provided as a tape and reel component, the CW25-TIM is specifically designed to be integrated with Communications devices such as GSM, CDMA, UMTS modems or any other communications medium. The CW25-TIM is optimized for the output of time/ frequency information.

Another aid to integration is the ability to store users’ software code in the CW25-TIM, reducing the need for external memory and processors.

Key Features of the CW25-TIM include:
  • 25 nsec accuracy to UTC
  • Enables indoor use -173 dBW acquisition and -185 dBW tracking
  • Rapid Time To Fix <2 second outdoors
  • 25 mm x 27 mm x 4.2 mm
