Hi everyone,
I have recorded a bag file which contains gps topic for using with robot_localization pkg. I want to modify my gps topic to mimic a scenario where gps signal is not available, e.g transition from indoor to outdoor and vice versa. Using [topic tools](http://wiki.ros.org/topic_tools) I was able to drop/filter out my gps messages. The result is in the following picture:
topic_tools drops X out of Y messages *regularly* as it is supposed to (blue dots). My question is: is there any method that can drop messages for ***a specific time length***? For clarification, I would like something like this:
where the yellow lines are my gps messages and the gaps between them are dropped gps messages.
I appreciate your help!
