Then, it will show a “TricklePower parameters”

dialog for parameters setting. There are two

parameters of Trickle power that needs to be set,

“Update Rate and On Time”. The “Update Rate”

means the navigation update frequency. For example,

“1 sec” means output once per second and “2 sec”

means output once per 2 seconds. The “On time”

means running time in the output period. For

example, “200 ms” means the running time is 200

ms per navigation update. The duty cycle of trickle

power is determined by setting of “Update Rate” and

“On Time”. For example, if the “Update Rate” is 1

sec and “On time” is 200ms, the duty cycle is

200ms/1000ms = 20%. If the “Update Rate” is 2 sec

and “On Time” is 300 ms, the duty cycle is

300ms/2000ms = 15%. The duty cycle is limited to

5% ~ 50%. Since it will do some estimation in

trickle power, please tune the proper duty cycle that

can compromise the power consumption and

acceptable navigation performance. The

“ricklePower Prameters” dialog is shown as
