AeroNav-1 Dual-Band GNSS (NavIC Supported)

The AeroNav-1 is an industrial-grade, dual-band GNSS module designed and manufactured in India by TeraVolt Labs. It is specifically engineered to support the NavIC (IRNSS) constellation, making it fully compliant with DGCA requirements for indigenous drone manufacturing. It features a high-sensitivity L1 + L5 receiver (Ublox-F10N) and an integrated Bosch BMM350 3-axis magnetometer for precise heading.

Key Features

  • NavIC Support: Native support for Indian Regional Navigation Satellite System (IRNSS) on L5 band.

  • Dual-Band Precision: Simultaneously tracks L1 and L5 signals for superior multipath rejection in urban environments.

  • Compass: Integrated Bosch BMM350 (Industrial Grade).

  • Compliance: Suitable for DGCA-compliant drone builds in India.
