How will GPS/GLONASS Chipset Integration Help the Consumer?
The integration of GPS and GLONASS systems within the same receiver offers many advantages to both the manufacturer and the end user. And now that this integration is happening at the chipset level, several further advantages can be added to the list.

On the basic technology level, the combination of GPS with GLONASS will provide greatly improved performance for the end user. The ability for the receiver to access signals from both constellations will provide greater availability, improved accuracy, faster time to first fix, wider coverage and improved performance in "difficult" environments, such as urban canyons. However, initial implementations have dictated that all these benefits come at a cost to the manufacturer (both in terms of design complexity and bill of materials), which is inevitably passed on to the end user.

Now, though, with the receiver integration taking place at the chipset level, the technology immediately becomes available to a wider ecosystem of manufacturers, and the benefits of this will clearly flow on to the consumer.

The latest devices recently released use state-of-the-art 45nm semiconductor processing, making the overall GNSS receiver both smaller and less power-hungry than previous implementations. The ability to build a complete GPS/GLONASS receiver with a reduced bill of materials and covering just 25 square millimetres of PCB real estate will mean that smaller and sleeker receivers can be built into an ever-wider range of end applications, with the reduced power consumption further saving space by reducing the space needed for battery power sources.

In the end, the consumer gets a GNSS receiver that is smaller, cheaper, more reliable, more accurate and more efficient.
