Quectel L80 GPS Module

Quectel L80 is an ultra-compact GPS POT (Patch on Top) module with an embedded 15.0mm × 15.0mm × 4.0mm patch antenna. This space-saving design makes L80 the perfect module for the miniature devices. Adopted by LCC package and integrated with a patch antenna, Quectel L80 GPS module has exceptional performance both in acquisition and tracking.

Combining advanced AGPS called EASY™ (Embedded Assist System) and proven AlwaysLocate™ technology, Quectel L80 achieves the highest performance and fully meets the industrial standard. EASY™ technology ensures L80 module can calculate and predict orbits automatically using the ephemeris data (up to 3 days) stored in internal RAM memory, so L80 can fix position quickly even at indoor signal levels with low power consumption. With AlwaysLocate™ technology, Quectel L80 GPS module can adaptively adjust the on/off time to achieve the balance between positioning accuracy and power consumption according to the environmental and motion conditions.

Quectel L80 module supports automatic antenna switching function. It can achieve the switching between an internal patch antenna and an external active antenna. Moreover, it keeps positioning during the switching process.

The Fitness Low Power (FLP) feature provides low power GPS solution for fitness application. It is an optimized solution for wearable, fitness and tracking devices and only costs about 50% power consumption of normal mode.

With its compact design, high precision and sensitivity, Quectel L80 GPS module 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.
