I would say its even more convenient to monitor binary format, since its
more compact and could be read as a structures
// u-blox UBX protocol essentials
typedef struct ubx_header {
unsigned char preamble1;
unsigned char preamble2;
unsigned char msg_class;
unsigned char msg_id;
unsigned short length;
} my_ubx_header;
typedef struct ubx_nav_timegps {
unsigned long iTOW_ms;
signed long fTOW_ns;
signed short week;
signed char leapS;
unsigned char valid;
unsigned long tAcc;
} my_ubx_nav_timegps;
typedef struct ubx_nav_timeutc {
unsigned long iTOW_ms;
unsigned long tAcc_ns;
signed long nano;
unsigned short year;
unsigned char month;
unsigned char day;
unsigned char hour;
unsigned char min;
unsigned char sec;
unsigned char valid;
} my_ubx_nav_timeutc;
and so on...

Who would have guessed a Russian OCXO. And, I guess the U-Blox is not
one of the better GPS units based on what Paul mentioned. But I think
there is software out there that will let me at least monitor what my
unit is doing and how many birds it is receiving data from.
Ublox makes excellent receivers. The monitoring software is fine.

But they dont talk (old) scpi.
