描述 Description

SIM68AD is a concurrent multi-GNSS receiver supporting dead reckoning function. It is equipped with a powerful GNSS core and a 6-axis IMU. SIM68AD is a standalone L1+L5 dual-band GNSS module in a LCC type with AIROHA’s high sensitivity navigation engine, which allows customer to achieve industry’s high level sensitivity, accuracy, and Time-to-First-Fix (TTFF) with lower power consumption.

SIM68AD provides simultaneous GPS, GLONASS, BeiDou, Galileo and QZSS open service L1 reception capability and GPS, BeiDou, Galileo and QZSS open service L5 reception capability. SIM68AD can acquire and track any mix of multiple satellite signals. Combining advanced AGPS called EASY? (Embedded Assist System) with proven AlwaysLocate? technology, SIM68AD achieves the highest performance and fully meets the industrial standard.
