This tri-band GNSS antenna is ideal for GPS L1, GLONASS L1, and Beidou B2 reception. At 45x45mm it is a large ceramic antenna with an incredible 38dB LNA gain.
This antenna works well with the GPS-RTK providing reception of Beidou satellites where other more basic GPS antennas cannot. We’ve chosen to have the antenna manufactured without an enclosure to decrease the weight (45g including cable) making this antenna more ideal for rover and quad-copter applications. Additionally, the cable length has been reduced to 1m to reduce weight and to make a more clean installation.
We recommend this antenna for RTK use when combined with the ground plate. This antenna is ideal for advanced raw, RTK, and post-processed measurements of GPS, GLONASS, and Beidou constellations. If all you need is GPS and GLONASS (basic GNSS) consider our lower cost magnetic mount GNSS antenna.
Antenna is terminated with a standard SMA connector. Check out the related items below for any conversion cables you may need.
Jargon buster
Plain-language definitions for the technical terms used above.
- 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.
- 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.
