Solutions for GPS Receiver Verification
Application Notes
Overview
One of the more compelling trends in the mobile phone market these days is the migration from dual-band to tri- and even quad-band designs. These complex phones must also now have the ability to handle various signals for peripheral radios such as Bluetooth®, FM, WLAN and WiMAX™ on a single integrated device. Another key functionality expected to become pervasive in mobile phones and other consumer electronic devices is Global Positioning System (GPS), a global navigation satellite system (GNSS) that provides precise location and time information based on an unobstructed line-of-sight to four or more GPS satellites. Over the years, GPS has become increasingly common in everyday life. Today it is used in everything from automotive navigation systems and geo-tracking to a range of locationbased services. While the GPS capability is a useful benefit for the consumer, it places added hardship on multi-function device manufacturers, OEM integrators and contract manufacturers who now have to determine the appropriate standard tests to verify GPS receiver performance, in addition to having to test any other supported wireless standards on their devices.
