Product overview
Tengxiang’s TX-RT005 is a waterproof RTK dual antenna module intended for centimeter-level positioning applications, including UAV mapping, inspection and delivery. Its dual-antenna signal fusion supports stable heading calculations and reduced positioning drift in complex environments. The antenna uses a quadrifilar helix architecture to support reception at low elevation angles and during tilt. Supported satellite systems comprise GPS L1/L2, BDS B1/B2/B3, GLONASS and Galileo, giving the module a role in multiconstellation positioning installations.
The module occupies a Φ27.5 x 59mm envelope and uses an SMA-J male-pin connector, defining its physical integration requirements. Its 2.2V to 16.0V DC input accommodates 3.3V/5V digital systems and 12V automotive power sources without extra regulators. The active antenna configuration includes 32±2dB gain, a noise figure of ≤1.5dB and a built-in band-pass filter for out-of-band interference rejection. Waterproof construction supports exposure to humidity, rain and dust, with an operating temperature range of -40°C to +85°C.
