(Ottawa, Ontario, Canada, Oct. 4, 2022) Calian GNSS Ltd. is excited to announce that it has added the housed AJ977XF triple-band antenna, with anti-jam technology to its industry-leading line of GNSS products.
The AJ977XF utilizes a novel stacked antenna phased array that creates a null, of typically 20 dB attenuation, in the antenna’s radiation pattern from the horizon to an elevation angle of approximately 15 degrees. The null in the radiation pattern strongly mitigates in-band and out-of-band signals. For example, the AJ977XF will continue to function in the presence of a ground-level 600-watt jamming signal, 100 metres or greater away from the antenna. In addition to the null in the radiation pattern, the antenna’s OP1dB (compression point) is 15 dBm which strongly protects the antenna’s LNA from saturating.
The triple-band AJ977XF antenna supports GPS L1/L2/L5, GLONASS G1/G2/G3, Galileo E1/E5ab and BeiDou B1/B2ab), and, in the region of operation, satellite-based augmentation systems (SBAS): [WAAS (North America), EGNOS (Europe), MSAS (Japan), or GAGAN (India)].
The AJ977XF is housed in a through-hole mount, weatherproof (IP67) enclosure. L-bracket (PN 23-0040-0) or pipe (23-0065-0) mounts are available for permanent installations.
The radio frequency spectrum has become congested worldwide as many new LTE bands have been activated. Their signals, or their harmonics, can affect the proper operation of GNSS antennas and receivers. In North America, the planned Ligado service, which will broadcast in the frequency range of 1526 to 1536 MHz, can negatively affect the reception of GNSS signals. Similarly, new LTE signals in Europe [Band 32 (1452 – 1496 MHz)] and Japan [Bands 11 and 21 (1476 – 1511 MHz)] have also been shown to affect GNSS signal reception. Tallyman’s new AJ977XF mitigates the effects of these new signals.
Trust Calian to provide clean and pure GNSS signals in a noisy RF world.
