name: STEC
full_form: Slant TEC
context: SSR STEC Corrections provides the GNSS receiver with the parameters to compute the ionosphere slant delay correction based on a variable order polynomial on a per satellite basis and applied to the code and phase measurements. For integrity purposes, SSR STEC Corrections also provides the ionosphere residual risk parameters, correlation time for ionosposphere range error and range error rate, and the mean and standard deviation that bounds the residual Ionospheric Error and its associated error rate.
description: STEC (Slant TEC) is a parameter used in GNSS receivers to compute ionosphere slant delay corrections. It is applied to code and phase measurements and also provides ionosphere residual risk parameters for integrity purposes.
explanation: The text explicitly states that STEC is a parameter used in GNSS receivers for computing ionosphere slant delay corrections, aligning with the definition of a parameter as a measurable value or factor influencing a system's behavior.
