1. An apparatus comprising:
a first antenna configured to receive a first signal;
a first Radio Frequency (RF) path configured to receive and process the first signal from the first antenna;
a first ADC configured to receive the processed signal from the first RF path and digitize the processed signal;
a communication modem configured to receive and process the digitized signal from the first ADC based on a modem clock to generate a first processed signal, the communication modem further configured to transmit the first processed signal, the communication modem further configured to transmit the first processed signal to a Digital to Analog Convertor (DAC) to convert the first processed signal from a digital signal to an analog signal and transmit the analog first processed signal to an R+1 antenna via an R+1 RF path;
a second antenna configured to receive a Global Navigation Satellite System (GNSS) signal;
a second RF path configured to receive and process the GNSS signal from the second antenna;
a second Analog to Digital Convertor (ADC) configured to receive and digitize the processed GNSS signal from the second RF path;
a filter configured to receive and filter the digitized GNSS signal from the second ADC;
a navigation channels configured to receive and process the filtered GNSS signal from the filter;
an R antenna to receive an R signal;
an R RF path configured to receive and process the R signal from the R antenna based on an R clock to generate a second processed signal;
an R ADC configured to receive and digitize the second processed signal from the R RF path;
a multichannel synchronous signals analysis system (MSSAS) configured to receive output of the first ADC, the second ADC, and the R ADC, and process the output of the first ADC, the second ADC, and the R ADC using a plurality of decimators, each decimator configured to output data to one of a respective plurality of data receivers; and
a CPU configured to control the first RF path, the second RF path, the R RF path, and the R+1 RF path, the first ADC, the second ADC, and the R ADC, the DAC, the communication modem, the filter, the navigation channel, and the MSSAS.
