kplockstat
This command prints the status, either locked or unlocked, of the front-panel keypad EDIT key.
When the EDIT key is locked, it will prevent unauthorized tampering with the unit. All other keys
are still enabled so you may continue to read the status and current settings of Meridian II. Refer to
the
lockoutkp
and
unlockkp
commands.

This command locks out access to the front-panel keypad EDIT key. When the EDIT key is locked,
it will prevent unauthorized tampering with the unit. All other keys are still enabled so you may

logrinex
This command is used to control logging of raw GPS pseudorange and carrier phase observations in
the Rinex version 2.11 format to the /home/rinex/rinex.log file. It requires one argument, which may
be either ON or OFF.
If ON is asserted and logging is not currently in progress, then a new log of 2880 observations taken
every 30 seconds will begin. Assuming full constellation visibility, this will take 24 hours to com-
plete. If a previously-initiated log is in progress, then an ON assertion will be ignored.
IMPORTANT!!! The data is always appended to the /home/rinex/rinex.log file, so if
you are performing multiple logs, it is up to you to manage the file and remove it
before it grows too large and fills the limited storage available.
If OFF is asserted, then any currently active log will be terminated. Data logged prior to the OFF
assertion is not discarded.
Once a complete log is available, you will need to prepend the Rinex version 2.11 header to it. An
example header is contained in a file in the same directory with the log file for reference:
/home/rinex/rinex_header_2.11
You will need to edit various fields in it for your requirements. When you have a complete log with
header, you may submit it to the Natural Resources Canada website for Precise Point Position (PPP)
processing using the CSRS-PPP tool. This is the only freely-accessible PPP tool that will perform
single-frequency PPP processing that we are aware of. The web URL is :
