Mini 3D Choke Ring Antenna
Multi-constellation and multi-frequency
The antenna supports full‑band multi‑constellation and multi‑frequency reception, covering GPS, GLONASS, GALILEO, BDS, QZSS, IRNSS, SBAS and L‑Band correction services. It tracks all mainstream navigation bands to deliver continuous, stable satellite signals, ensuring global positioning compatibility and high accuracy for surveying, monitoring, and base station applications.
Small size and light weight
TCA930M features a compact small size and light weight with official dimensions of Φ185mm×148mm and a weight of ≤2.5Kg. The miniaturized choke ring structure saves installation space while retaining full high‑performance GNSS reception. It supports standard 5/8″-11 mounting for fast, stable deployment. The lightweight and compact design greatly eases transportation, field installation, and system integration, ideal for surveying, monitoring, and base station applications with limited space.
Robust and reliable structure, stable phase center
TCA930M is built with a robust and reliable structure that delivers exceptional durability for long‑term outdoor operation. Adopting a professional choke ring design and patented multi‑point feeding technology, it achieves outstanding phase center stability with precise repeatability within ±1mm. The phase center and geometric center are highly aligned to minimize measurement deviation, ensuring consistent positioning accuracy. It performs steadily under harsh environments, making it perfectly suitable for surveying, monitoring, and mission‑critical base station applications.
Wide frequency range, versatile application areas
TCA930M offers an extended wide frequency range that fully covers GPS, GLONASS, GALILEO, BDS, QZSS, IRNSS, SBAS and L‑Band correction signals. It supports multi‑band synchronous reception to maintain strong and stable satellite tracking. This versatile antenna is widely applied in land and marine surveying, channel measurement, landslide monitoring, structural deformation detection, wharf operations, and various high‑precision base station scenarios.
The 5th generation IMU technology
The TCA930M integrates advanced 5th‑generation IMU technology, delivering ultra‑high motion sensitivity and real‑time attitude calculation. It enhances dynamic positioning stability, ensures fast satellite reacquisition, and maintains high precision under vibration or movement for surveying and monitoring applications.
