101 – NavigationInitialization
This command is used to initialize the receiver with the current position (in
X, Y, Z coordinates), clock offset, and time, enabling a faster fi x. Increased
receiver sensitivity and the removal of Selective Availability (SA) have made
this unneccessary. The command is retained for its ability to reset the
module, but the initialization fi elds are no longer supported.
