Jumpstar JS-AP55
Multi-Band Multi-Constellation GNSS Receiver
The JS-AP55 is a high-performance multi-band, multi-constellation satellite receiver with rich data interfaces. It provides two versions: single-antenna (AP55) for high-precision positioning and dual-antenna (AP55H) for accurate heading & attitude output.
With 448 hardware channels and over 2 million valid correlators, it tracks all visible GNSS signals at the same time. It features ultra-low latency (<10ms), 100Hz default update rate, and exclusive anti-jamming, ionospheric suppression and multipath mitigation technologies, ensuring stable signal tracking under high-frequency vibration and rapid movement.
Built-in TCXO, LNA and TF card slot (up to 32GB), it is the ideal core positioning module for UAVs, intelligent robots, precision control, autonomous driving and other high-end applications.
