Have you changed the convergence time of survey-in of LC29HBS?
The default convergence time of LC29HBS is 43200 times, so it is definitely impossible to output a fixed position in a short time.
You can verify it as follows.

  1. Send the command “$PQTMCFGSVIN,W,1,300,15,0,0,0*15” to configure the Survey-in mode. After positioning, when the 3D threshold is less than 15 and the cumulative count is 300 times, the Survey-in is completed.
  2. Send the command “$PQTMSAVEPAR*5A” to save the Survey-in configuration command.
  3. Send the command “$PQTMCFGMSGRATE,W,PQTMSVINSTATUS,1,1*58” //Open PQTMSVINSTATUS and check the convergence status of Survey-in.
    The command format is shown in the figure.
    When the <Obs> value is equal to <CfgDur>, it means that Survey-in is completed.

  4. When Survey-in is completed, you can send the command “$PQTMCFGMSGRATE,W,PQTMSVINSTATUS,0,1*59” to close PQTMSVINSTATUS message.
