Based on the STMicroelectronics Teseo II positioning engine, L16 is a single GNSS receiver module integrated with GLONASS,GPS, Galileo and QZSS system. It accomplishes simultaneous GNSS open service L1 reception. With 32 tracking channels and 2 fast acquisition channels, L16 can acquire and track any mix of GNSS signals. Compared with using GPS only, enabling both GPS and GLONASS generally doubles the number of visible satellites, reduces the time to first fix and increases positioning accuracy, especially when driving in rough urban environments. Its super performance is perfectly suitable for automotive, consumer and other industrial applications.

Applications

●  STMicroelectronics TeseoII single chip solution

●  Simultaneously use GLONASS and GPS system

●  32 tracking channels and 2 fast acquisition channels

●  Highly dynamic indoor sensitivity of -162dBm in tracking mode (Note2)

●  Higher autonomous acquisition mode sensitivity, -148dBm

●  Full ESD protection on all pins

●  High performance ARM946 MCU (up to 208MHz)

●  In-Package SQI 16Mbits Flash Memory

●  Superior performance even in the toughest urban environments

●  Up to 5Hz update rate

●  Support ST-AGPS self Assisted-GPS technology

●  Support DGPS: RTCM104, SBAS(WAAS, EGNONS)

Packaging
The module is sensitivity to moisture absorption. Before reflow, Module should be baked for 192 hours at temperature 40℃+5℃/-0℃ and <5% RH in low-temperature containers, or 24 hours at temperature 125℃±5℃ in high-temperature containers. Care should be taken that plastic tray is not heat resistant. Module should be taken out before preheating, otherwise, the tray maybe damaged by high-temperature heating.
