1. A method comprising:
receiving from a plurality of radiofrequency receivers, a plurality of baseband signals, each of the plurality of baseband signals generated from a radiofrequency signal from a GNSS antenna and a pilot reference signal, wherein the pilot reference signal is the same for each of the baseband signals and each of the plurality of baseband signals is amplified and below a thermal noise floor;
calculating, by a computing device, a phase offset, a time offset, and a power offset for each of the plurality of baseband signals based on the pilot reference signal; and
adjusting, by the computing device, each of the baseband signals based on the calculated phase offset, time offset, and power offset for each of the plurality of baseband signals.
