Description
The GPVSF.25.8.A.08 is a compact, high-performance stacked patch antenna designed to support GNSS L1 and L5 operation with IRNSS compatibility. It is optimized for fast positioning and improved navigation accuracy, including deployments that require IRNSS support.
- Multi-band operation: Supports L1 and L5 bands for enhanced positioning performance
- Directional performance: Designed to deliver strong radiation characteristics for reliable signal reception
- Integration-friendly: Intended for embedded designs where a controlled ground plane is available
Typical applications include:
- UAVs and Robotics
- Transportation
- Marine
- RTK
- Autonomous Vehicles
- Agriculture
- Navigation
Installation / Environmental
The following is an example on how to integrate the GPVSF.25.8.A.08 into a design. The GPVSF.25.8.A.08 has one pin which is used for the RF Feed. It is recommended using a minimum of 70x70mm ground plane to ensure optimal performance.
