GPS Testing for receiver and equipment for accuracy, range and sensitivity to TIA-916 specifications.

Intertek has the experienced staff and facilities—including a Spirent C2K rack with GPS testing capabilities and a fully anechoic chamber to support testing equipment for accurate results. Our quality testing and quick turnaround  helps you meet product cycle deadlines and ensure conformity to standards such as Assisted GPS (A-GPS) and other positioning protocols.

What is Assisted GPS (aGPS or A-GPS)? 
The Federal Communications Commission (FCC) in the U.S. has worked to improve the quality and reliability of 911 emergency services with the Wireless Communications and Public Safety Act of 1999. As part of this, the FCC has required wireless service providers to implement enhanced 911 services. One requirement of this Act is the implementation of an assisted Global Positioning System (GPS). A-GPS ensures the acceleration for startup performance (including Time-to-First-Fix, TTFF) of a GPS system through the utilization of another data source.  

We provide testing support for specific sections of TIA-916 that evaluate various performance attributes of wireless handsets and other devices, including:

  • section for GPS accuracy
  • section for GPS dynamic range
  • section for GPS sensitivity
  • section for GPS multipath accuracy
  • section for moving scenario GPS accuracy
  • section 3.2.1 for advanced forward link trilateration (AFLT) accuracy
  • section 3.2.2 for AFLT sensitivity
