AC4990TXF Multi-Constellation Full-Band Precision GNSS Antenna

The AC4990TXF is a precision-tuned multi-constellation, full-band Accutenna® 4 technology antenna. Supported constellations and signals are, GPS/QZSS-L1/L2/L5 QZSS-L6, GLONASS-G1/G2/G3, Galileo-E1/E5a/E5b/E6, BeiDou-B1/B2/B2a/B3, NavIC-L5, including the satellite- based augmentation system (SBAS) available in the region of operation [WAAS (North America), EGNOS (Europe), MSAS (Japan), or GAGAN (India)], plus L-band Corrections.

The AC4990TXF features a precision-tuned, twin circular quad-feed, stacked patch element. The signals from the four orthogonal feeds are combined though a feed network, amplified in a wideband LNA, then band-split for narrow filtering in each band and further amplified prior to recombination at the output. The AC4990TXF quad-feed Accutenna® 4 technology enables an excellent axial ratio (strongly mitigating multipath) and a tightly grouped phase centre variation (≤ 2 mm from zenith to 15° above horizon). It is ideal for surveying, autonomous vehicle tracking and guidance, precision agriculture, and other applications where precision matters.

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 that support space-based L-band Corrections (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 Calian 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 housed AC4990TXF has a rugged through-hole metallic base, and a weatherproof enclosure for permanent installations.

CR8894SXF+ Anti-Jamming Four Element Controlled Reception Pattern Antenna (CRPA)

Calian’s CR8894SXF+ GNSS Controlled Reception Pattern Antenna (CRPA) can mitigate/null one (1) interference or jamming signals in both the lower (1189 -1254 MHz) and upper (1559 – 1591 MHz) GNSS bands for a total of two (2) nulls. The CR8894SXF+ 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.

Interference or jamming can saturate a standard GNSS antenna’s Low Noise Amplifier (LNA), making it unusable. Calian’s CR8894SXF+ uses two interference-mitigating technologies: eXtended Filtering+ (XF+) and 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 is 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 CR8894SXF+ 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 military, drone, and vehicle applications. The CR8894SXF+ CRPA is surface-mounted using four screws. A standard RF connector (SMA or TNC) and serial interface connectors are centrally located, properly sealed to prevent water ingression.

A future version of CR8894SXF+ antenna will support three (3) nulls per band.

CR7712EXF Anti-Jam Two Element Controlled Reception Pattern Antenna (CRPA)

Calian’s CR7712EXF embedded Controlled Reception Pattern Antenna (CRPA) GNSS antenna steers 1 planar null to mitigate interference or jamming signals in the upper GNSS band (1559 – 1606 MHz). The output of the CR7712EXF is a standard RF signal (compatible with all Commercial Off The Shelf (COTS) GNSS receivers) with the interference/jamming signals removed. The CR7712EXF also has a serial interface that provides antenna state information indicating jamming detected or not. This feature allows the user to quickly understand the GNSS signal status.

The CR7712EXF utilizes the patented Tallysman Accutenna® technology and a new very low power analog interference detection and mitigation methodology. The product integrates the antenna, interference mitigation, and null forming technology into a light weight and compact enclosure.

The CR7712EXF is a 2-element CRPA designed for single-band Global Navigation Satellite System (GNSS) signal reception. It supports: GPS L1, Galileo E1, GLONASS G1 and BeiDou B1 signal bands. The wide bandwidth antenna elements support the GPS M-Codes on L1.

Intentional and unintentional interference or jamming can saturate a standard GNSS antenna’s Low Noise Amplifier (LNA) such that it may not provide a usable signal. Calian’s CR7712EXF employs two interference mitigating technologies: eXtended Filtering (XF) and Controlled Reception Pattern Antenna (CRPA). XF provides > 80 dB of out of band rejection from 400 MHz to 3000 MHz. Additionally, XF has very sharp band edges around the GNSS bands. CRPA technology creates radio frequency nulls in the direction of the interference/jammer and as a result the antenna provides a clean GNSS signal.

The CR7712EXF embedded CRPA is surface mounted using screws. A standard antenna radio frequency MCX connector and a serial interface connector are the interfaces provided.
