This is a simple way to initalize logging via serial on a Novatel PP6 and PP7 GPS receiver.

This assumes that you are using a USB->Serial cable that will appear as /dev/ttyUSB0 in a unix environment. If you are using a USB->Serial cable that does not exist at /dev/ttyUSB0 e.g. /dev/ttyUSB1 etc... you will need to pass the argument to the bash script:

for a device located at /dev/ttyUSB0

~$ sudo ./internal_log_start_novatel.sh 0

for a device located at /dev/ttyUSB1

~$ sudo ./internal_log_start_novatel.sh 1

Usually, in linux, the USB-Micro port on the PP6 or PP7 reciever comes in to the laptop as /dev/ttyUSB0 but be sure to check on your machine.

when the device is first started up, you must send:

~$ sudo ./novatel_start.sh 0 and make sure that you get an response when the script is finished.

to log the specified post processed values needed for PPK internally on the PP6

~$ sudo ./internal_log_start_novatel.sh 0 and make sure that the green LED next to the disk icon is flashing green at 1hz.

to stop the internal log on the PP6

~$ sudo ./internal_log_stop_novatel.sh 0 and make sure that the green LED next to the disk icon is not flashing green.

to log the specified post processed values needed for PPK internally on the PP7

~$ sudo ./internal_log_start_novatel_pp7.sh 0 and make sure that the green LED next to the disk icon is flashing green at 1hz.

to stop the internal log on the PP7

~$ sudo ./internal_log_stop_novatel_pp7.sh 0 and make sure that the green LED next to the disk icon is not flashing green.

to start logging base station survey data on PP7 ~$ sudo ./base_station_log.sh 0 and make sure that the green LED next to the disc icon is flashing green at 1hz.

this data can be used later to post process the antenna location for surveying the basestation accurately.

to start the autosurvey function. only use for relative accuracy tests ~$ sudo ./autosurvey.sh 0

to start publishing corrections from the master receiver, on com 1, at 57600 baud ~$ sudo ./base_station_enable.sh 0

Note:

This also assumes that you have configured the Novatel receiver (rover) using the SERIALCONFIG command to set up the basic serial configuration.

Example:

SERIALCONFIG <yourSerialPort> 115200 N 8 1 N ON
