The SSL889XF employs Calian’s unique Accutenna technology providing dual band GPS L1/L2, GLONASS G1/G2/G3, Galileo E1/E5b, and BeiDou B1/B2 coverage and is specially designed for precision dual-frequency positioning where light weight is important.

The SSL889XF features a precision-tuned, circular dual feed, stacked patch element. The signals from the two orthogonal feeds are combined in a hybrid combiner, amplified in a wide-band LNA, then band-split for narrow XF filtering in each band and further amplified prior to recombination at the output.

The radio frequency spectrum has become more congested as new LTE bands are activated and their signals or harmonic frequencies [e.g. 800MHz x 2 = 1600MHz (GLONASS-G1)] can affect GNSS antennas and receivers. In North America, planned Ligado signals at 1525 – 1536 MHz can especially impact GNSS antennas. New LTE signals in Europe [Band 32 (1452 – 1496 MHz)] and Japan [Bands 11 and 21 (1476 – 1511 MHz)] have also been observed to interfere with GNSS signals. In addition, Inmarsat satellite communication (uplink: 1626.5 – 1660.5 MHz) can also affect GNSS signals. Caliaan’s XF antennas have been designed to mitigate out-of-band signals and prevent GNSS antenna saturation. Calian’s custom XF filtering mitigates all existing signals and new Ligado and LTE signals, enabling the antennas and attached GNSS receivers to perform optimally.

The SSL889XF antenna is available in three mechanical configurations. Configuration 1,2, and 3 as shown.
