Canadian positioning sensor developer Calian GNSS has launched two superior antenna options designed for precision navigation purposes: the HC3990XF housed full-band helical antenna and the next-generation Accutenna 4 antenna household, with the latter showcased at Intergeo 2025.
HC3990XF Technical Specs
The HC3990XF helical antenna measures 66.5 mm in base diameter, 34 mm in peak, and weighs simply 105 grams. The antenna requires no floor airplane, making it splendid for size-constrained purposes. It helps complete constellation protection together with GPS/QZSS-L1/L2/L5, QZSS-L6, GLONASS-G1/G2/G3, Galileo-E1/E5a/E5b/E6, BeiDou-B1/B2a/B2b/B3, and NavIC-L5 frequency bands, plus regional SBAS providers.
The antenna options Calian’s eXtended Filtering expertise, offering mitigation in opposition to LTE interference together with Ligado service indicators (1526-1536 MHz), European Band 32 (1452-1496 MHz), and Japanese Bands 11 and 21 (1476-1511 MHz). Normal through-hole design helps TNC, Kind N, and cabled connectors.
Accutenna 4 Household Options
The Accutenna 4 sequence makes use of a stacked composite patch antenna component with quad-feed design at half the load of main rivals. The embedded model weighs 85 grams and gives full GNSS band protection supporting GPS, Galileo, BeiDou, GLONASS, SBAS, and correction providers. The superior four-feed design minimizes multipath interference whereas sustaining steady part middle efficiency for centimeter-level accuracy.
Accessible mounting choices embrace embedded, pole, floor, and through-hole configurations. The antenna integrates eXtended Filtering expertise for interference rejection in crowded RF environments.
“GNSS customers want full band antennas they will belief to ship clear indicators in real-world environments,” mentioned Ken MacLeod, Director of Product Administration. “The Accutenna 4 household brings collectively precision, sturdiness and flexibility in 4 packages: embedded, pole, floor and thru gap mounts, empowering clients in surveying, autonomy, agriculture and extra”.
Each antenna households goal purposes together with UAV navigation, precision agriculture, surveying, and autonomous methods the place weight, dimension, and RF interference rejection are vital efficiency elements.
