Decoding RAP report


I Have around 100 bus equiped with GX440 and GX450 modems.

I am trying to colect GPS RAP Reports to track the odometer of each modems. I’m looking for the documentation on the RAP report format but cant find it anywhere.

The data send by each modem is in binary and i need to decode it.

Where can I fond this documentation ?

Thank you for the assistance

I am also interested in the answer, did you have it ?
