TW5390 Smart GNSS Antenna; High Precision; IMU; L-Band; u-blox ZED-F9R + NEO-D9S
The TW5390 is a multi-band (L1/L2), multi-constellation integrated GNSS receiver/antenna with Inertial Measurement Unit (IMU) (for Untethered Dead Reckoning) and integrated L-Band receiver for PointPerfect Flex PPP-RTK corrections. The TW5390 is capable of providing sub 1 meter accuracy stand alone, sub 6 cm accuracy with PPP-RTK corrections and sub 1 cm with RTK corrections. Combined with the IMU to achieve Sensor Fusion, TW5390 supports the most demanding positioning applications in the most challenging environments such as a dense urban canyon and off-grid positioning.
Interference Resilience
The TW5390 incorporates a latest generation multi-band (L1/L2) GNSS receiver and IMU with a Tallysman Accutenna® multi-band (L1/L2/L-Band) triple band dual feed patch. The state of the art GNSS receiver supports concurrent tracking of all four major constellations (GPS, BeiDou, Galileo and GLONASS ) in multiple frequency bands. The multi-band (L1/L2) architecture is highly effective method for the removal of ionospheric error. The TW5390 employs multi-stage filtering with low noise figure LNAs, combined with the dual feed Accutenna®, which greatly improves the rejection of multi-path signal interference. The IMU Sensor Fusion further mitigates effects of severe multi-path reflections and provides continuous position availability during periods of GNSS signal obstruction offering exceptional performance to meet the most challenging precise positioning applications.
Precision Point Positioning
The TW5390 offers support for a broad range of corrections services (RTCM RTK, networked PPP-RTK or PointPerfect Flex PPP-RTK over L-Band ) allowing performance optimization according to each application’s unique requirements. The concurrent multi-band (L1/L2) access to all four satellite constellations improves the receiver’s convergence capability to deliver a quick, precise and reliable position solution which is resilient to ionospheric errors and improves resilience against interference and jamming. As an RTK rover, The TW5390 accepts RTCM RTK messaged from a base
station, Virtual Reference Station or SPARTN SSR message type via the PointPerfect Flex subscription service or commercial network RTK services such as Point One Navigation Polaris RTK and Swift Navigation Skylark Precision Positioning.
The TW5390 provides sub 6 cm positioning accuracy in conjunction with PointPerfect Flex PPP-RTK corrections and sub 1 cm accuracy with RTK. TW5390 can receive PointPerfect Flex PPP-RTK corrections over L-Band when outside of terrrestrial networking coverage.

HC977SXF Multi-Constellation Triple-Band Antenna
The patented HC977SXF helical antenna is designed for precision positioning, covering the GPS/QZSS-L1/L2/L5, GLONASS-G1/G2/G3, Galileo-E1/E5a/E5b, BeiDou-B1/B2b/B2a, and NavIC-L5 frequency bands, including the satellite-based augmentation system (SBAS) available in the region of operation [WAAS (North America), EGNOS (Europe), MSAS (Japan), or GAGAN (India)], as well as L-Band correction services.
Weighing only 32 g, the light and compact HC977SXF features the 2nd generation Tallysman precision-tuned helix element that provides excellent axial ratios and operates without the requirement of a ground plane, making it ideal for a wide variety of applications, including unmanned aerial vehicles (UAVs). 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 HC977SXF features an industry-leading low current, low-noise amplifier (LNA) that includes an integrated low-loss pre-filter. eXtended Filtering was added to the HC977 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 enclosure’s base provides two threaded inserts for secure attachment, as well as a rubber O-ring around the outer edge to seal the antenna base and its integrated male SMA connector.
