I am looking for the Pseudoranges from the Satellite to the GPS receiver mounted on the Husky robot. I thought maybe I could find them logged in the message which has the data type "nmea_msgs/Sentence" however when I use :

rosmsg show nmea_msgs/Sentence

I get this error : Unable to load msg [nmea_msgs/Sentence] : Cannot locate message [Sentence]: unknown package [nmea_msgs] on search path ................ and the error goes on

Any clue why is this happening ? , rosmsg show is working find with all other message types

Thanks in advance,

Naz

nmea_msgs appears to only be available for hydro and newer: http://wiki.ros.org/nmea_msgs

Does that mean I will not be able to comprehend message with datatype Sentence (from package nmea_msgs) ? . Does this mean my only option would be migrating to hydro from fuerte ? Is there any way around it ?

You can likely install it from source into your workspace.

Try installing the nmea_msgs package: sudo apt-get install ros-hydro-nmea-msgs (assuming you're running ROS Hydro and Ubuntu).

Having said that, with the command you're trying to run you'll only be able to see the message specification, and I can anticipate that the nmea sentence is of type "string".

I hope it helps.

I will try to install it and check if it works...I am actually running fuerte and Ubuntu would the command be :

sudo apt-get install ros-fuerte-nmea-msgs ?

I get this error

E: Unable to locate package ros-fuerte-nmea-msgs

Thanks,

Naz
