8.1.1 “A” Commands

agpspde

This command is used to configure Assisted GPS (A-GPS) parameters on supported wireless data

cards/modules.

The cellular device chipset contains a GPS receiver. Position Determine Equipment (PDE) assists the

cellular device to speed up satellite acquisition, the PDE sends satellite almanac and ephemeris

information to the device.

Currently this feature only works on later model Sierra Wireless data devices that support A-GPS

(USB598, USB597). When a later model Sierra Wireless data device is used with a modem configured in

half bridge mode, A-GPS support is not available and must be disabled.
