Slide 11: Advantages of soldering (1)
Advantages of soldering(1) t e l l e c t i a u Q fide n on L80 is a GPS POT (Patch on Top) module. Its patch antenna’s feed point is embedded in the PCB. So the feed point is concave, rather than convex . There is no need to hollow out the feed point. C L80 has 12 pins, which are very practical
Slide 12: Advantages of soldering (2)
Advantages of soldering(2) t e l l e c t i a u Q fide n on L80 can be easily soldered into all kinds of evaluation boards through five cables (RXD,TXD,VCC,GND C and V_BCKP), which is convenient for different customers to evaluate the module’s performance on their own boards. Base on simple desig
Slide 13: Self-AGPS EASY Technology (1)
Self-AGPS EASY Technology(1) l EASY™ is the abbreviation for Embedded Assist System for quick positioning. With EASY™ t e l technology, the GPS engine can calculate and predict automatically single ephemeris ( up to 3 days) when the power is on, and then save the predict information into the memor

Slide 15: Automatic Antenna Switching Function (1)
Automatic Antenna Switching Function(1) l Patch Antenna Status ct e a l u e n t i Q fide on C Notes: 1. The patch antenna is used by default, and the “OPEN” is displayed in the GPTXT sentence of NMEA. 2. The L80 module with patch antenna could achieve 3D fix even inside the concrete buildings.
Slide 16: Automatic Antenna Switching Function (2)
Automatic Antenna Switching Function(2) l External Active Antenna Status(1) ct e a l u e n t i Q fide Notes: on C 1. When the external active antenna is connected well, L80 module will switch to use external active antenna automatically. L80 module keeps positioning during the switching process. 2
Slide 17: Automatic Antenna Switching Function (3)
Automatic Antenna Switching Function(3) l External Active Antenna Status(2) ct e a l u e n t i Q fide on C Notes: 1. When external active antenna is removed, the internal patch antenna of L80 module will take effect automatically because of antenna switching function. During the switching process,
Slide 18: Automatic Antenna Switching Function (4)
Automatic Antenna Switching Function(4) l External Active Antenna Status(3) ct e a l u e n t i Q fide on C Notes: 1. If external active antenna short-circuited or damaged, L80 module will use internal patch antenna automatically. There is no need to worry about position fixing because L80 module i
Slide 19: Periodic Standby Mode
Periodic Standby Mode Periodic standby mode can control power on/off time of GPS periodically to reduce average power l consumption, and on/off time can be configured by using PMTK command. For details, see the figure below. e Periodic standby mode can be entered by sending the following PMTK comman
Slide 20: AlwaysLocate Technology
tm AlwaysLocate Technology e l AlwaysLocate™ is an intelligent controller of periodic mode. ct a l L80 can adaptively adjust the on/off time to achieve balance between positioning accuracy e i and power consumption according to the environmental and motion conditions. So the t average power consum
