[Via Satellite 10-03-13] Spirent Communications has introduced a carrier-approved Assisted Global Navigation Satellite System (A-GNSS) record and playback capabilities on its Hybrid Location Technology Solution (HLTS). This new A-GNSS record and playback capability provides realism and repeatability by recording GNSS signals in the field and delivering synchronized assistance data over a radio access interface to test the A-GNSS positioning performance of mobile devices in the lab.

Although established A-GNSS simulation tools play an important role in generating repeatable and reliable controlled environments in the lab, they can have limitations when it comes to representing the full range of challenging conditions experienced by mobile users on live networks. Spirent’s A-GNSS record and playback addresses these limitations by capturing conditions in the field and playing them back in a reliable and repeatable lab environment. This helps to reduce device time to market and control testing cost by reducing the need for extensive field testing.
