Dear all,
I meet a problem about the gpsdo for lock. First I check
the usrp->get_mboard_sensor("gps_locked",0); it
indicates the gps is locked. Then the program is sleep
for 5 mins. Then I check the gps again but in this time
it does not lock. I do not think that in this 5 mins the
gps lost lock because every time I try like this, the
first time it is locked but after 5 mins it is unlocked,
as follows:
The reference clock is:GPS lock status: locked
Setting device clock source to:external
Setting device clock rate to:1e+08
Setting time source to:external
The reference clock is:GPS lock status: unlocked
