ARM990XF Multi-Constellation Full-Band Antenna

Calian is excited to announce that it has added the ARM990XF full-band plus L-Band GNSS antenna to its industry-leading line of GNSS antenna products. The ARM990XF employs Calian’s patented Accutenna® technology providing GPS/QZSS L1/L2/L5/L6, GLONASS-G1/G2/G3, Galileo E1/E5a/E5b/E6, and BeiDou B1/B2a/B2b/B3, NavIC L5 + L-Band coverage. The ARM990XF antenna is designed for precision full-frequency positioning where lightweight and a low profile are important.

The ARM990XF antenna is available in two form factors one includes a 100 mm integrated ground plane, weighing 140 g, and the other one is 83mm in diameter and weighs 138 grams. Both are 19 mm tall and support the ARINC mini bolt pattern of 2.0” x 1.66”. Calian’s ARM990XF is one of the smallest and lightest housed triple-band precision Mini ARINC GNSS antennas on the market. It has a very tight average phase center variation of less than 10 mm for all frequencies and overall azimuths and elevation angles. In addition to supporting two form factors both models are available with Low Earth Orbit (LEO) qualified components.

Housed in a weatherproof enclosure, the ARM990XF is available in four versions. Model ARM990XF-1 has an integrated 100mm ground plane, Model ARM990XF-2 is 83 mm in diameter. All models are available with either a female SMA or TNC connector.

The new ARM990XF antenna supports Calian’s eXtended Filtering (XF) technology. Worldwide the radio frequency spectrum has become congested as many new LTE bands have been activated, and their signals 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 signals. 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. Calian’s XF technology mitigates all these signals.

All models are available with either a female SMA or TNC connector.

TW3887XF

Embedded Multi-Constellation Dual-Band Antenna

The TW3887XF is a precision-tuned dual-band Accutenna® technology antenna providing coverage for GPS/QZSS-L1/L2, GLONASS-G1/G2, Galileo-E1, and BeiDou-B1, including the satellite-based augmentation system (SBAS) available in the region of operation [WAAS (North America), EGNOS (Europe), MSAS (Japan), or GAGAN (India)].

The TW3887XF features an industry-leading low current, low-noise amplifier (LNA) that includes an integrated low-loss pre-filter to prevent harmonic interference from high-amplitude signals, such as 700 MHz band LTE and other near-band cellular signals. As the radio frequency spectrum has become more congested, the signals and harmonic frequencies of new LTE bands [e.g. 800MHz x 2 = 1600MHz (GLONASS-G1)] can affect GNSS antennas and receivers. In North America, planned Ligado signals at 1525 – 1536 MHz could 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 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.
Ideal for train control sensors, autonomous vehicle tracking and guidance, precision agriculture, and other applications where precision matters, the TW3887XF provides superior multipath signal rejection, a linear phase response, and tight phase centre variation (PCV).

The TW3887XF features a precision-tuned, twin circular dual-feed, stacked patch element. The signals from the two orthogonal feeds are combined in a hybrid combiner, amplified in a wideband LNA, then band-split for narrow filtering in each band and further amplified prior to recombination at the output.3 The TW3882XF offers excellent axial ratio and a tightly grouped phase centre variation.

The signals from the two orthogonal feeds are combined in a hybrid combiner, amplified in a wideband LNA, then band-split for narrow filtering in each band and further amplified prior to recombination at the output. The antenna also has a strong pre-filter to mitigate inter-modulated signal interference from LTE and other cellular bands. The TW3997 offers excellent axial ratio and a tightly grouped phase centre variation.

Smart Choke Ring for High Precision GNSS Base Station Applications 

TW170

TW170 Coaxial GNSS RF Surge Protector

The Calian TW170 is a professional-grade coaxial GNSS full-band surge protector, or lightning arrestor, that interfaces a GNSS antenna to its corresponding receiver, while protecting the receiver from high-voltage strikes. The product supports GPS/QZSS-L1/L2/L5, QZSS-L6, GLONASS-G1/G2/G3, BeiDou-B1/B2/B2a/B3, Galileo-E1/E5a/E5b/E6, NavIC-L5, and L-Band correction services.

Using a highly tuned design based on a gas discharge tube (GDT), the TW170 can handle a surge current of up to 20 kA, effectively isolating the receiver from damaging electrical currents as a result of lightning strikes or static discharge on the GNSS antenna.

The TW170 offers the best in-class performance for connectivity, input and output VSWR, and low transmission losses. In addition, it is packaged in a robust, compact, lightweight, and water-proof (IP67) corrosion-protected stainless-steel housing.

The TW170 also provides a continuous DC power path, from output to input, to feed outdoor electronic circuits like GNSS antennas, etc.

TW164B

TW164B 1-to-4 Port Smart Power GNSS Signal Splitter

The Calian TW164B is a professional-grade full GNSS band signal splitter that connects one antenna up to four receivers, and supports GPS/QZSS-L1/L2/L5, QZSS-L6, GLONASS-G1/G2/G3, BeiDou-B1/B2/B2a/B3, Galileo-E1/E5a/E5b/E6, NavIC-L5, and L-Band correction services. This model has all four receiver ports in-line on the backside of the splitter, with the antenna port located on the frontside.

GNSS has become a critical component in safety, security, timing, and infrastructure applications, all of which require very high availability. As a result, resilient fault-tolerant components are essential to avoid service interruptions.

The design of first-generation GNSS signal splitters suffered from a single point of failure: only one attached receiver powered the splitter and the antenna. If this receiver failed or was unplugged, all attached receivers also failed.

Calian’s current-generation TW164B Smart Power GNSS signal splitter provides two additional key features:

First, it accepts power from all attached GNSS receivers and selects power from a receiver using the following protocol. Port #1 is given priority if its voltage is within the specified range (3.3 – 12.5 VDC). However, if port #1’s receiver is disconnected or if its receiver power goes below the under-voltage or above the over-voltage specification, the TW164B will switch to the next port in numerical order, as long as its power and voltage are within the expected range. The switching and port selection is, therefore, deterministic.

Second, if the antenna fails and does not draw current, the TW164B will provide all connectors with a current draw lower than 1 mA, indicating an antenna fault.
The TW164B offers the best in-class performance in terms of noise figure, isolation, and linearity. In addition, it is packaged in a robust, compact, lightweight, and waterproof (IP67) corrosion-protected aluminum housing.

The TW164B is available with either TNC or type-N connectors and offers standard gain to compensate for signal-splitting loss.
It is recommended that unused ports should be terminated with a 50 Ohm load.

TW165B

TW165B1-to-4 Port Smart Power GNSS Signal Splitter (10 dB gain)

The Calian TW165B is a professional-grade full GNSS band signal splitter that connects one antenna up to four receivers, and supports GPS/QZSS-L1/L2/L5, QZSS-L6, GLONASS-G1/G2/G3, BeiDou-B1/B2/B2a/B3, Galileo-E1/E5a/E5b/E6, NavIC-L5, and L-Band correction services.
