The SSL889XF utilizes Calian’s unique Accutenna technology, providing dual-band coverage for GPS L1/L2, GLONASS G1/G2/G3, Galileo E1/E5b, and BeiDou B1/B2. It is specifically designed for precision dual-frequency positioning where lightweight is crucial.
Key Features:
- Precision-Tuned Design: The SSL889XF features a circular dual-feed, stacked patch element. Signals from the two orthogonal feeds are combined in a hybrid combiner, amplified in a wide-band LNA, band-split for narrow XF filtering in each band, and further amplified before recombination at the output.
- Advanced Filtering: The radio frequency spectrum is increasingly congested with new LTE bands. These signals, or their harmonic frequencies (e.g., 800MHz x 2 = 1600MHz for GLONASS-G1), can interfere with GNSS antennas and receivers. In North America, planned Ligado signals (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.
- Mitigation of Interference: Calian’s XF antennas are designed to mitigate out-of-band signals and prevent GNSS antenna saturation. The custom XF filtering effectively mitigates existing signals and new Ligado and LTE signals, ensuring optimal performance of the antennas and attached GNSS receivers.
