AssistNow is a standard A-GPS service that enhances the performance of the GPS receiver by calculating a position almost instantly, even in difficult reception conditions. A-GPS enhances all GPS-enabled applications, especially those that require constant operational readiness, such as fleet management applications or GPS-enabled handheld devices whose users want immediate access to location-based services, regardless of reception conditions.
Without A-GPS, a GPS receiver must locate at least 4 satellites in direct line of sight and then download their location data. This process takes 30 seconds in optimal reception conditions and can take much longer in poorer conditions, e.g. in an urban environment or inside a building where GPS reception is weaker. AssistNow sends the data directly to the GPS receiver, enabling a quick position calculation.
The offline service provides assistance data that is valid for up to 14 days. Users can therefore benefit from increased satellite acquisition performance for longer periods of time and only occasionally need an internet connection to update the support data.
1Depends on accuracy of correction data of DGPS or SBAS service
2 CEP = Circular Error Probability:The radius of a horizontal circle, centreed at the antenna's true position, containing 50% of the fixes.
3 SEP = Spherical Error Probability.The radius of the sphere, centered at the true position, contains 50% of the fixes.
