Our Assisted-Global Navigation Satellite System (A-GNSS) solution leverages multiple Wide-Area Reference Networks (WARN) to provide real-time almanac and ephemeris data for a variety of applications. The A-GNSS reference data feeds are based on satellite network information from around the world: - GPS (US) - GLONASS (Russia) - BDS (China) - Galileo (Europe) - QZSS (Japan) - NavIC (India) Partnering with NASA, we gather raw data from a variety of satellites and receivers and generate meaningful location information. This creates efficiencies for mobile devices and location enabling platforms. ## How You Benefit from Comtech’s A-GNSS Solution ### 1 Location-based platforms and services benefit from A-GNSS data to compute precise location. ### 2 Enhances device location performance by improving time to first fix. ### 3 Comtech’s A-GNSS solution is used by Mobile Network Operators, Femtocell implementations, SmallCell Gateways, IoT and M2M manufacturers. ### 4 Flexible deployment models such as Comtech-hosted or on customer premises. ![WARN GNSS image - 1 (1)](https://www.comtechlocation.com/hubfs/WARN%20GNSS%20image%20-%201%20(1).webp) ## Global location and messaging solutions customized for your business needs.
