SKG121D is a single receiver module integrating GPS, BeiDou, GLONASS and Galileo systems. It is able to achieve the industry’s highest level of sensitivity, accuracy and TTFF with the lowest power consumption in a small-footprint lead-free package. The embedded flash memory provides capacity for
storing user-specific configurations and allows for future updates.

The SKG121D module supports multiple positioning and navigation systems including autonomous GPS, BeiDou, GLONASS, Galileo, SBAS (including WAAS, EGNOS, MSAS and GAGAN), QZSS, DGPS, and AGPS.

Features:

◆ GPS/GLONASS/BDS/ GALILEO/QZSS receiver

◆ Ultra high sensitivity: -162dBm

◆ Extremely fast TTFF at low signal level

◆ Supports Dead Reckoning (DR) function

◆ ±25ns high accuracy time pulse (1PPS)

◆ SBAS (WAAS,EGNOS,MSAS,GAGAN)

◆Embedded with a 3-axis Gyroscope and 3-axis Accelerometer

◆ UART0: Supports baud rates from 4800bps to 115200bps; 115200bps by default

◆UART0 port is used for NMEA output and firmware upgrade

◆ Small form factor: 16.2 x 12.2 x 2.4mm

◆ FCC compliance

◆ RoHS compliance (Lead-free)

◆ CE certificated
