Description
SIM68MLB is a high performance and reliable GNSS module. It is a GNSS module integrated with GPS & BeiDou system 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.
SIM68MLB provides simultaneous GPS, BeiDou, and QZSS open service L1 reception capability. With 33 tracking channels and 99 acquisition channels, SIM68MLB can acquire and track any mix of multiple satellite signals. Combining advanced AGPS called EASY? (Embedded Assist System) with proven AlwaysLocate? technology, SIM68M achieves the highest performance and fully meets the industrial standard.
