Product overview

The SKYLAB SK4A65C is a miniaturized anti-interference integrated GNSS device for UAVs, unmanned vehicles and other small mobile platforms. Its integrated assembly combines a four-element antenna, RF module, anti-interference processing unit and GNSS receiver, supporting BDS B1, GPS L1 and Galileo E1 signals. It suppresses interference from up to three directions to improve positioning and navigation stability in complex electromagnetic environments. Anti-interference capability reaches ≥110dB @ -130dBm with a single interference source and ≥100dB @ -130dBm with three interference sources.

Measuring 65mm × 65mm × 24mm and weighing ≤125g, the SK4A65C operates from DC 9~15V with typical power consumption ≤9W across an operating temperature range of -40°C ~ +70°C. Horizontal and vertical positioning accuracy are each ≤10m, with velocity accuracy ≤0.2m/s. Acquisition sensitivity is -145dBm and tracking sensitivity is -160dBm. NMEA0183 or UBX output runs at a 1Hz data update rate. An SMA-K interface connects an external receiver, while a J30J-9ZK interface provides power and serial communication, with LVTTL 3.3V logic support.
