Abstract: ABSTRACT TITLE: FIRMWARE-DRIVEN MULTI-SATELLITE ASYNCHRONOUS CLOCK CORRECTION RECEIVER FOR LEO NAVIGATION A multi- satellite LEO navigation receiver system (100) comprising a wideband signal acquisition front-end module (110) with a multi-band antenna unit (112), radio-frequency down-conversion chain (114), and analog-to-digital converter array (116); a multi-channel delay-Doppler extraction engine (120) with a field-programmable gate array based parallel correlator bank (122); a differential correction interface module (140); a firmware-based timing correction workflow engine (150); an adaptive satellite visibility manager (160); and a navigation state estimator (170). The timing correction workflow engine (150) sequentially processes per-satellite asynchronous clock corrections through a satellite-wise correction sequencer (152), validates each through a multi-criterion correction validity assessor (158), applies validated corrections through a measurement-domain correction applicator (154), and injects posterior clock covariance through an uncertainty propagation calculator (156). The estimator (170) maintains a compact eight-state extended Kalman filter enabling statistically consistent positioning. [Figure 1]
