AssistNow is a standard A-GPS service that enhances GPS receiver performance 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 instant 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 under optimal reception conditions and can take much longer under poorer conditions, such as in an urban environment or inside a building where GPS reception is weaker. AssistNow sends the data immediately to the GPS receiver, enabling fast position calculation.

The offline service provides assist 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 need an occasional internet connection to update the support data.

1 Depends on accuracy of correction data of DGPS or SBAS service.

2 CEP = Circular Error Probability: The radius of a horizontal circle, centred 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.
