Smart GNSS Antennas

Integrated GNSS antenna/receiver systems for Positioning, Navigation & Timing

Smart GNSS Antennas

Calian GNSS Smart Antennas combine our cutting-edge antenna technology with integrated high-precision GNSS receivers, Inertial Measurement Units (IMUs), application processors and diverse digital interfaces to deliver flexible solutions that fit a broad swath of applications, from drones to smart agriculture to autonomous vehicles to subsidence sensors and even survey applications.

Cost competitive single band solutions provide excellent solutions for telematics and timing, and include IMUs to assist in satellite obstructed “deep urban canyon” scenarios or even 100% satellite obstructed situations such as parkades.

Ublox Thingstream Design partnerDual-band high precision solutions incorporate advanced high precision GNSS receivers from partners such as u-blox, delivering the cm level precision required for autonomous driving applications and sensitive subsidence applications.

Base or Rover RTK capability, or u-blox PointPerfect PPP-RTK services combined with IMU’s, application processors and digital interfaces such as RS-232 or RS-422, transform GNSS challenges into a plug and play Positioning, Navigation and Timing resource, enabling you to focus on your application rather than the difficult problem of GNSS signal reception.

Get started on your application quickly by verifying performance with one of our Software Development Kits, which include Smart Antenna, TruPrecision evaluation/configuration software and bundle a 60 day trial of u-blox PointPerfect PPP-RTK service (where applicable).

Helical Technology

Advanced helical antennas for low-SWaP PPP/RTK applications

Calian Helical Antennas

Calian’s helical antennas are designed for SWaP (size, weight and power)-critical and high-performance applications such as UAVs. A precision-tuned helix antenna element delivers excellent gain and axial ratio over all elevation and azimuth angles, significantly minimizing multipath. Low-noise amplifiers (LNAs) with integrated low-loss pre-filters ensure high signal-to-noise ratios and excellent interference mitigation.

Being very light weight, and performing well without a ground plane, Calian’s helical antennas are ideal for UAV, unmanned systems precise point positioning (PPP), and real-time kinematic (RTK) applications.

The Helical antenna family features:

  • Ultra-light weights ranging from 4 to 42 g
  • Broad GNSS band coverages, including single, dual, triple, and full band options, with L-band correction service offerings
  • Embedded versions and robust military-grade IP67-compliant plastic enclosed variants
  • Certified Iridium options

Anti-Jam Technology

Robust single-band anti-jamming antennas

single-band anti jamming antennas

Calian’s single-band (L1/G1/E1/B1) Accutenna anti-jamming technology modifies the antenna radiation pattern so that jammer signals arriving from an elevation angle of +15 to -10 degrees above and below the horizon are blocked. In addition, antenna gain is slightly increased at high elevation angles.

The robust anti-jamming antennas can mitigate ground- or near ground-based jamming signals that can saturate the antenna’s Low Noise Amplifier (LNA) and prevent legitimate satellite signals from being passed to the GNSS receiver.
