The TX2504-3T7A21C-WG-DT is a highly integrated, miniaturized anti-jamming GNSS navigation module, engineered to deliver reliable high-precision positioning for compact unmanned systems and industrial automation applications. This all-in-one solution combines a 7-element CRPA antenna array, a high-performance anti-interference processor, and a multi-constellation GNSS receiver into a single, lightweight, space-saving form factor. Supporting all major global navigation satellite systems (BDS, GPS, GLONASS, Galileo), it maintains uninterrupted, accurate positioning performance in complex, signal-challenged industrial environments, making it the ideal navigation solution for robotics, civilian drones, and mobile industrial equipment.

Powered by advanced 7-element array anti-jamming technology, this module delivers exceptional interference suppression capabilities, with an interference suppression ratio (ISR) of ≥110dBc against a single jammer, ≥100dB against 3 simultaneous jammers, and ≥90dB against up to 6 concurrent interference sources. This ensures stable, unbroken navigation even in RF-congested industrial zones, urban canyons, and high-interference field environments.
Unlike bulky split-type anti-jamming solutions, this integrated miniaturized anti-jamming GNSS module achieves an optimal balance of performance, size, and weight. With a compact Φ220mm ×20.5mm form factor and a total weight of ≤1200g, it is perfectly suited for weight- and space-constrained applications such as small drones and mobile robots, without compromising on anti-interference performance.
Supporting four global navigation constellations, this antenna delivers global coverage and redundant positioning capability, ensuring reliable operation across all geographic regions. Its all-in-one design eliminates the need for separate processors and receivers, reducing integration complexity and total system cost, making it a cost-effective choice for high-volume industrial deployments.
This robotics high-precision GNSS antenna is optimized for compact industrial and unmanned system scenarios, including civilian and commercial drones for aerial surveying and agricultural mapping, autonomous mobile robots (AMRs) and automated guided vehicles (AGVs) for industrial automation and warehouse logistics, ground robotics for outdoor inspection and security patrol, precision agriculture equipment, and urban infrastructure inspection devices for smart city operations.
