BR1 GPS caching?

I’ve been searching through the specs and all over trying to find if any of peplinks units have this ability. Essentialy if the GPS is being sent over Cell and the cell goes down but the vessel is still moving is there a way to cach that information and then have it send once Cell is recovered.

Supported MAX routers can automatically store up to seven days of GPS location data in GPS exchange format (GPX). See: Accessing GPS Info from Pepwave MAX Routers
