In North America, planned Ligado signals at 1525 – 1536 MHz can especially impact GNSS antennas that support space-based L-band correction services (1539 -1559 MHz). 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. The new Tallysman 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 CR8894PXF+ is a 4-element CRPA designed for dual-band Global Navigation Satellite System (GNSS) signal reception. It supports GPS L1/L2, Galileo E1/E5b, GLONASS G2/G3, and BeiDou B1/B2b signal bands. The wide bandwidth antenna elements also support GPS M-Codes on both L1 and L2. Contact us to request a datasheet.

Interference or jamming can saturate a standard GNSS antenna’s Low Noise Amplifier (LNA), making it unusable. Calian’s CR8894PXF+ uses two interference-mitigating technologies: eXtended Filtering+ (XF+) and a Controlled Reception Pattern Antenna. XF+ features > 80 dB of out-of-band rejection from 400 MHz to 3000 MHz and separates the LNA’s upper and lower signal amplification channels, if one channel is jammed the other remains usable. CRPA technology creates radiation pattern nulls in the direction of the interference/jammer, preventing LNA saturation and ensuring a usable GNSS signal. The output is a standard RF signal with the interference removed and a signal that is compatible with all Commercial Off The Shelf (COTS) GNSS receivers. The CR8894PXF+ also incorporates marine filtering where Iridium and Inmarsat signals from 1616 to 1660 MHz are rejected.

The CR8894PXF+ uses Tallysman Accutenna® technology and a low-power analog interference detection and mitigation methodology. It integrates the antenna, null-forming, and interference mitigation technology into a compact, lightweight surface-mount enclosure. Two serial interfaces are provided: one supports RS232, the other RS422. These interfaces output NMEA messages that contain jamming detection, mitigation status, jammer band, and direction relative to the antenna, enhancing situational awareness.

The lightweight, waterproof (IP69K) rugged enclosure withstands harsh conditions including marine, and land-based, jamming detection applications. The CR8894PXF+ CRPA is a pole mount antenna specially designed with marine and land-based environments in mind, supporting 5/8″-11 TPI or 1″-14 TPI inserts. A standard RF connector (TNC or N-Type) and serial interface connectors are provided, properly sealed to prevent water ingression.

The miniaturized 2nd generational helical element is about 25% lighter and 20%(1 cm) shorter than the first generational helical, without compromising on performance such as peak gain at zenith, low roll-off, and bandwidth.

The HC976SXF features an industry-leading low current, low-noise amplifier (LNA) that includes an integrated low-loss pre-filter. eXtended Filtering was added to the HC976 antenna to mitigate new radio frequency bands that interfere with GNSS signals. For example, new LTE bands have been activated, and their signal 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). Similarly, 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.

Field tests have confirmed that Calian’s custom XF technology mitigates the new (Europe and Japan) and existing LTE signals, enabling the XF antenna to produce clean and pure GNSS radio frequency data.

Calian’s 2nd generation housed helical antenna elements are protected by a robust military-grade IP67 plastic enclosure.

The AJ979XF+ MAR Anti-Jam antenna is designed to mitigate interference and jamming signals broadcast from near ground-based transmitters. The radiation pattern of the Low Elevation Angle Nulling Antenna (LEANA) provides 20 dB (typical) wideband suppression for all GNSS band signals received at an elevation angle of 0° through to approximately 15°. This level of attenuation was demonstrated to mitigate jamming signal broadcasts at an elevation angle of 10° such that the AJ979XF+ MAR can be up to 10 times closer, compared to a standard HC977XF helical antenna, to the source of interference without being jammed. The combination of Calian’s low elevation angle nulling radiation pattern and eXtended Filtering (deep filtering and high linearity) technologies provides a one-two punch to jamming and RF noise. At the same time, the AJ979XF+ MAR’s radiation pattern above 20° elevation angle provides excellent gain and a phase center that supports accurate and precise positioning.

Calian’s eXtended Filtering+ (XF+) technology features > 80 dB of out-of-band rejection from 700MHz to 2500MHz and separates the LNA’s upper and lower signal amplification channels; if one channel is jammed the other remains usable. In North America, Ligado signals at 1525 – 1536 MHz can especially impact GNSS antennas that support space-based L-band correction services (1539 – 1559 MHz). 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, and the AJ979XF+ MAR provides strong rejection of marine L-band interference sources including Iridium and Inmarsat signals from 1616 to 1660 MHz, supporting reliable GNSS performance in challenging maritime RF environments.
