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 ionosphere range error and range error rate, and the mean and standard deviation that bounds the residual Ionospheric Error and its associated error rate.
description: The Slant TEC (STEC) is a parameter used in GNSS receivers to compute ionosphere slant delay corrections. It is based on a variable order polynomial applied per satellite basis for code and phase measurements. Additionally, STEC Corrections provide integrity parameters such as ionosphere residual risk, correlation time, range error rate, mean, and standard deviation of the residual Ionospheric Error and its associated error rate.
explanation: STEC is classified as a Parameter because it refers to specific values or settings used in GNSS receivers for correcting ionospheric delays. The context highlights its role in providing necessary data for accurate satellite-based positioning.
