Abstract

The present invention provides a message broadcast apparatus and method for enhanced parameters in a satellite navigation system. The apparatus includes: a processor, which determines the insertion position of the enhanced parameter in the reserved space in the navigation message frame structure model according to the byte size and the broadcast frequency of the enhanced parameter that needs to be broadcast, so as to perform the message arrangement of the enhanced parameter; and a transmitter, which uploads the arranged message to the broadcast satellite for broadcasting the message.
