Calian Adds Three New Multi-Constellation, Full-Band Accutenna GNSS Antennas

Calian® GNSS is excited to announce the addition of a line of multi-constellation, full-band Accutenna® GNSS antennas to its TW3000 XF antenna family.

The new full-band Accutenna® line supports three models: Housed TW3990XF (37dB gain), Embedded TW3990EXF (37dB gain), and TW3997XF (28dB gain). All models support GPS/QZSS (L1/L2/L5), QZSS L6, GLONASS (G1/G2/G3), Galileo (E1/E5a/E5b/E6), BeiDou (B1/
B2a/B2b/B3), NavIC L5, and L-Band correction services.

Calian Adds Three New Multi-Constellation, Full-Band Accutenna® GNSS Antennas to Its TW3000 Xf Antenna Family

The key new feature of the TW3000 XF family of antennas is the support for Galileo’s Global High Accuracy Service (HAS) and QZSS’s regional Centimeter Level Augmentation Service (CLAS); both correction services are broadcast in the E6/L6 band (1258-1300 MHz).

The radio frequency spectrum has become congested worldwide as many new LTE bands have been activated, and their signals or harmonic frequencies can affect GNSS antennas and receivers. In North America, the planned Ligado service, which will broadcast in the frequency range of 1526 to 1536 MHz, can affect GNSS antennas that receive space-based L-band correction service signals (1539 – 1559 MHz). New LTE signals in Europe [Band 32 (1452 – 1496 MHz)] and Japan [Bands 11 and 21 (1476 – 1511 MHz)] have also affected GNSS signals. Lastly, the Inmarsat satellite communication uplink (1626.5 – 1660.5 MHz) commonly used on maritime vessels can also affect nearby.

GNSS antennas. Calian’s custom XF filtering has been tested to mitigate new (Europe and Japan) and existing LTE signals, enabling the XF antennas to produce clean and pure GNSS radio frequency data.

Calian’s TW3000 XF family of antennas is ideal for a variety of applications, including unmanned autonomous vehicle navigation (land, sea, and air), land survey devices, automotive positioning, timing, and other precise positioning applications.

Trust Calian to provide clean and pure GNSS signals in a noisy RF world.
