The feasibility and potential accuracy of employing GPS signals and mobile receivers as a very long base interferometry (VLBI) network for precision geodesy is explored. The primary listening devices would be large radio telescopes tuned to both quasars and GPS spacecraft. The mobile units would densify the receiver network, particularly for the GPS signals. Numerical models are defined for the SNR, expected errors, and bandwidth synthesis to lower the SNR. A block diagram is provided for a mobile receiver which would treat the GPS signals as white noise. Finally, software features are considered which would be necessary for simulating the system and establishing effective operational and data processing procedures.
