GPS Testing for Receivers & Equipment
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 220.127.116.11 for GPS accuracy
- section 18.104.22.168 for GPS dynamic range
- section 22.214.171.124 for GPS sensitivity
- section 126.96.36.199 for GPS multipath accuracy
- section 188.8.131.52 for moving scenario GPS accuracy
- section 3.2.1 for advanced forward link trilateration (AFLT) accuracy
- section 3.2.2 for AFLT sensitivity
