DESCRIPTION

The gps_conf utility is used to specify whether a GPS receiver module is present and if so, which model is provided. It also specifies the interval between samples of the GPS location, and the number of samples to be averaged.

The PAM7Q module provides a report every two seconds, but a sample interval of 10 seconds is usually appropriate. The averaging tally depends on the mode of use of the device: for a fixed device, 10 minutes (60 samples) is effective in rejecting "quality 0" readings, whereas a mobile device requires a tally of 1.

The u-blox PAM-7Q and SAM-M8Q GPS modules are supported.

The REPORT_FILE parameter, if set, indicates where the latest queue length value should be stored.

The status_sampler must be restarted for changes to take effect.

SYNOPSIS

gps_conf.py [{ [-m MODEL] [-i INTERVAL] [-t TALLY] [-l { 0 | 1 }] | -d }] [-v]

Options
--version	show program's version number and exit
-h, --help	show this help message and exit
-m, --model	set the model (PAM7Q or SAM8Q)
-i SAMPLE_INTERVAL, --sample-interval=SAMPLE_INTERVAL	set sampling interval (seconds)
-t TALLY, --tally=TALLY	set the averaging tally
-l DEBUG, --debug=DEBUG	set debug logging (default is 0)
-d, --delete	delete the GPS configuration
-v, --verbose	report narrative to stderr

EXAMPLES

./gps_conf.py -m SAM8Q -i 10 -t 60 -l 1
