Overview

The Beitian RTK integrated positioning module series is a multi-system, dual-frequency GNSS receiver module for vehicle control and mobile positioning. It supports BDS (BeiDou), GPS/QZSS, GLONASS, Galileo, NAVIC/IRNSS and SBAS signals (model-dependent), and provides TTL / RS-232 / USB-level serial data output options depending on the selected model.

Key Features

  • Multi-system dual-frequency GNSS reception (BeiDou B1I/B1C/B2I/B2a; GPS/QZSS L1C/A, L5; GLONASS G1; Galileo E1, E5a; NAVIC/IRNSS L5; SBAS L1, L5) (model-dependent)
  • Supports RTK centimeter-level positioning (RTK accuracy: Horizontal 0.01m+1ppm CEP; Vertical 0.02m+1ppm CEP)
  • High-performance output: default baud rate 115200 bps; maximum 2000000 bps; RTK update rate up to 10 Hz
  • Time accuracy (1PPS): 20ns
  • Low power operation: 30mA/5.0V; input voltage DC 3.6V-5.5V (typical 5.0V)
  • Dual-layer antenna structure (stacked antenna design)
  • TX and PPS indicator lights
  • Configuration supports retention after power outage (FLASH-related description provided for BP-280 indicators table)
