Advanced GNSS Antennas
Integrated GNSS antenna and receiver systems for precise Positioning, Navigation & Timing
Calian GNSS smart Antennas merge our advanced antenna technology with integrated high-accuracy GNSS receivers, Inertial Measurement Units (IMUs), application processors, and various digital interfaces to provide adaptable solutions suitable for a wide range of applications, from drones and smart agriculture to autonomous vehicles and subsidence sensors, and also surveying tasks.
Our competitively priced single-band solutions offer remarkable performance for telematics and timing, featuring IMUs to aid in scenarios with satellite obstructions, such as in dense urban environments or entirely obstructed areas like parking garages.
Our dual-band high-precision solutions utilize advanced GNSS receivers from partners like u-blox, achieving centimeter-level accuracy essential for autonomous driving and sensitive subsidence monitoring.
With capabilities for Base or Rover RTK, or u-blox PointPerfect PPP-RTK services, combined with IMUs, application processors, and digital interfaces such as RS-232 or RS-422, we transform GNSS challenges into a straightforward Positioning, Navigation, and Timing resource, allowing you to concentrate on your application rather than the complexities of GNSS signal reception.
Kickstart your application development by testing performance with one of our Software Development Kits, which include smart Antenna, TruPrecision evaluation/configuration software, and a 60-day trial of u-blox PointPerfect PPP-RTK service (where applicable).

Anti-Jamming Solutions
Durable single-band anti-jamming antennas
Calian’s single-band (L1/G1/E1/B1) Accutenna anti-jamming technology alters the antenna’s radiation pattern to block jamming signals that arrive from an elevation angle of +15 to -10 degrees above and below the horizon. Additionally, the antenna gain is slightly enhanced at higher elevation angles. These robust anti-jamming antennas effectively mitigate ground-based or near-ground jamming signals that can overwhelm the antenna’s Low Noise Amplifier (LNA), preventing legitimate satellite signals from reaching the GNSS receiver.
