The BT-T009 is a compact, lightweight multi-band GNSS helical antenna supporting L1, L2, and L5 frequencies across GPS, GLONASS, Galileo, and BeiDou constellations. Designed for permanent mount applications with a four-screw installation for tamper resistance. Weighs just 22g with a standard SMA connector.
L5 is the third civilian GPS signal, designed for high-accuracy applications. When used in combination with L1 and L2, the triple-band configuration provides a highly robust positioning service. Best suited for installations with a clear view of the sky.

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- Galileo
- Europe’s satellite navigation system. Galileo support can improve satellite availability and accuracy, especially when combined with GPS and other constellations.
- GLONASS
- Russia’s satellite navigation system. A receiver that can also use GLONASS has more satellites to choose from, which can improve positioning reliability when the sky view is partly blocked.
- GNSS
- GNSS stands for Global Navigation Satellite System, covering positioning systems such as GPS and similar satellite networks. It matters here because high-precision GNSS modules can output lots of serial position data that this product can send wirelessly to a computer or phone.
- GPS
- The US satellite navigation system used by GNSS receivers to calculate position and time. Support for GPS is important because it is widely available and often used together with other constellations for more reliable positioning.
- 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.
- RTK
- Real-Time Kinematic positioning is a GNSS technique that uses correction data from a base station to greatly improve location accuracy. It matters if you need centimetre-level positioning for robotics, mapping, surveying, or tracking rather than ordinary metre-level GPS accuracy.
- 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.
