Receive data processing device for TDMA satellite communications network

Claim 1

A receive data processing device installed in a reference ground station which totally monitors and controls operating conditions of two or more other ground stations which constitute a ground traffic system of TDMA satellite communications channels, said device comprising: data store means for temporarily storing channel monitoring information signals which respectively are associated with operating conditions of the ground stations and separated from n (particular positive integer) sequences of receive burst signals, which are received by way of an n-channel transponder loaded in a predetermined communication satellite, and predetermined burst identification signals for identifying the channel monitoring information signals in correspondence with the respective ground stations; write control means for temporarily storing in the data store means associated with the n sequences of receive burst signals the channel monitoring information signals and burst identification signals associated respectively with the predetermined ground stations which correspond to the respective sequences; read control means for sequentially specifying in response to a predetermined read data sequence specify signal the channel monitoring information signals and the burst identification signals which are temporarily stored in the data store means and associated respectively with the ground stations which are associated with the n sequences of received burst signals, and then reading out the specified information signals each by an amount which is specified by the read data sequence specify signal; detector means for detecting amounts of data stored in data store areas of the data store means which respectively are associated with the ground stations in the n sequences in response to predetermined write data amount indication signals and read data amount indication signals which respectively are outputted from the write control means and the read control means during a write control operation and a read control operation, and then generating the read data sequence specify signal which gives priority to a particular one of the data store areas having stored the greatest amount of data and specifies a particular amount of data to be read out; multiplexer means for multiplexing the channel monitoring information signals and the burst identification signals which respectively are associated with the ground stations in the n sequences and sequentially read out of the data store means; and ground station monitor means for classifying the multiplexed channel monitoring information signals and the burst signals outputted from said multiplexer means and associated with the respective ground stations in the n sequences, and functioning to monitor use of the TDMA system which is related to operating conditions of the respective ground stations.
