Compact GNSS Module with Embedded Patch Antenna

L86 is an ultra compact GNSS POT (Patch on Top) module with an embedded 18.4×18.4×4.0mm patch antenna and utilizes the MediaTek new generation GNSS chipset MT3333 that achieves the perfect peorformance. Designed to be compatible with Quectel GPS L80 module In the compact and unified form factor, it provides a flexible and scalable platform for migrating from GPS to GNSS. This saving-space design makes L86 the perfect module for the miniature devices. Adopted by LCC package and integrated with patch antenna, L86 has exceptional performance both in acquisition and tracking.

Combining advanced AGPS called EASY™ (Embedded Assist System) and proven AlwaysLocate™ technology, L86 achieves the highest performance and fully meets the industrial standard. EASY™ technology allows L86 to calculate and predict orbits automatically using the ephemeris data (up to 3 days) stored in internal flash memory, so L86 can fix position quickly even at indoor signal levels with low power consumption. With AlwaysLocate™ technology, L86 can adaptively adjust the on/off time to achieve balance between positioning accuracy and power consumption according to the environmental and motion conditions.

L86 supports automatic antenna switching function. It can achieve the switching between internal patch antenna and external active antenna. Moreover, it keeps positioning during the switching process.

With its tiny design, high precision and sensitivity, L86 is perfectly suitable for a broad range of M2M applications such as portable device, automotive, personal tracking, security and industrial PDA, especially suitable for special applications, like GPS mouse and OBD.
