From page 114...
... In less sophisticated aiding systems, often referred to as "Ioosely-coupled" structures, inertial positions and GPS positions or pseudorange data are merged in a cascaded filler structure, missing the benefits of improved GPS signal tracking margins. However, these loosely-coupled INS/GPS structures do extend the length of time that inertial operations can provide useful accuracy and a GPS integrity check, and also speed GPS signal acquisition.
