Jargon buster
Plain-language definitions for the technical terms used above.
- Active GNSS antenna
- An active GNSS antenna has a built-in amplifier that needs power from the board. It can improve satellite signal reception, but you need to use an antenna that matches the board’s powered antenna connection.
- B2a
- A BeiDou satellite signal used by newer dual-band GNSS receivers. Support for B2a can improve accuracy and reliability when combined with other GNSS bands.
- E5a
- A Galileo satellite signal band used for higher-performance positioning services. Support for E5a can help dual-band GNSS receivers improve accuracy and reduce errors from atmospheric delay.
- ground plane
- A ground plane is a large area of copper on a circuit board connected to ground. It helps provide a stable return path for signals and is especially important for reducing noise in high-speed connections.
- L5
- A modern GNSS signal band used by several satellite systems for more accurate and robust positioning. Dual-band receivers that include L5 can often perform better than single-band receivers, especially for RTK and areas with reflected signals.
- SMA
- A threaded coaxial connector commonly used for antennas. It matters because you need antennas with matching SMA connectors, or suitable adapters, for the LTE and GNSS antenna ports.
