GNSS Receiver and Location-Based Services

Location-Based Services put Pressure on GNSS Receiver Performance

The addition of GPS receivers to today's smartphones, netbooks and other internet enabled devices is allowing mobile operators and other service providers to exploit a growing market for location-based services. These can range from social networks offering “find a friend” applications, to location based marketing and advertising. And you can be sure that developers will come up with many more new applications for location data as the market matures.

Regardless of the nature of the service, all location-based services put GNSS receiver performance at a premium. After all, there is no point in giving a user a mobile coupon for a business they passed just ten seconds ago, and telling them they are standing within 10 metres of it when they can clearly see they are 100 metres away, this is hardly likely to endear them to any service. While assisted GPS can play a role in the equation, operator-independent location-based services rely purely on the performance of the GNSS receiver in the user's equipment.

The growth of such services means that it is now even more important to ensure that your GNSS receiver design delivers the best possible performance under all operating conditions. And the only way of verifying this performance is by simulating all those possible conditions using a GNSS simulator.
