توضیحات
Quectel L80-R 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-R the perfect module for the miniature devices. Adopted by LCC package and integrated with patch antenna, L80-R has exceptional performance both in acquisition and tracking.
Combining advanced AGPS called EASY™ (Embedded Assist System) technology, L80-R achieves the highest performance and fully meets the industrial standard. EASY™ technology ensures L80-R can calculate and predict orbits automatically using the ephemeris data (up to 3 days) stored in internal RAM memory, so L80-R can fix position quickly even at indoor signal levels with low power consumption.
With its compact design, high precision and sensitivity, L80-R 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.

EASY™ is the abbreviation for Embedded Assist Syst m for quick positioning. With EASY™
Quectel
technology, the GPS engine can calculate and predict au omatica y sing e ephemeris ( up to 3 days)
when the power is on, and then save the predict informa ion into the memory. So the GPS engine
can use the information for positioning later if there are not nough information received from the
satellites. Confidential
This function will be helpful for positioning and TTFF improvement under indoor or urb n conditions
