Product overview
The ZD-Motor 2501-AJS-4CH-DPA combines an antenna array, anti-jamming module and GNSS receiver in one compact device for UAVs and industrial applications. Its dual-frequency receiver supports GPS L1 and BDS B1I signals and is compatible with BeiDou-3. The integrated unit provides satellite navigation anti-jamming and anti-spoofing functions. Measuring 150 mm × 130 mm × 22 mm, it weighs ≤ 520g and consumes ≤ 13 W at room temperature.
Broadband anti-jamming capability resists up to three jammers simultaneously, with unidirectional interference suppression of ≥ 105 dB and three-way suppression of ≥ 95 dB. Supported interference types include band-limited white Gaussian noise, matched spectrum spread spectrum, pulse, scan and mixed interference. Anti-interference coverage spans an azimuth of 0 ~ 360° and altitude of -90 ~ 90 °. Output residual spoofing signal C/N0 is ≤ 20 dB. RF output frequencies are 1561.098 MHz / 1575.42 MHz, with output power of -70 ~ -60 dBm.
