The processing module includes a dual-processing-satellite-differencing module, a double differencing module, and a gradient estimator module. The dual-processing-satellite-differencing module is operable to: receive carrier phase measurements for at least two satellites from at least two reference receivers; implement a first processing mode to normalize first satellite differences between +λ/2 and −λ/2; implement a second processing mode configured to normalize second satellite differences between 0 and λ; and select for further processing one of: data indicative of the first satellite differences processed according to the first processing mode; and data indicative of the second satellite differences processed according to the second processing mode. The double differencing module forms double-differences based on the selected data input from the dual-processing-satellite-differencing module. The gradient estimator module estimates a magnitude of the horizontal delay gradient."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ground-based system and method to extend the detection of excessive delay gradients using dual processing","description":"A processing module to monitor a horizontal delay gradient in satellite signals is provided.
