SSL825XF

The SSL825XF employs Calian's unique Accutenna technology, providing dual-band coverage for GPS L1/L5, GLONASS G1/G3, Galileo E1/E5a/E5b, and BeiDou B1/B2a/B2b. It is specifically designed for precision dual-frequency positioning where light weight is important.

Key Features

• Precision-Tuned Design: The SSL825XF features a precision-tuned, circular dual-feed, stacked patch element. 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 before recombination at the output.

• Interference Mitigation: As the radio frequency spectrum becomes more congested with new LTE bands, their signals or harmonic frequencies (e.g., 800 MHz x 2 = 1600 MHz for GLONASS-G1) can affect GNSS antennas and receivers. In North America, planned Ligado signals at 1525-1536 MHz can particularly 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. Additionally, Inmarsat satellite communication (uplink: 1626.5-1660.5 MHz) can affect GNSS signals.

• Advanced Filtering: Calian's XF antennas are 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.
