Abstract
Dual-frequency receiver for satellite-based positioning, comprising a main measurement channel and a secondary channel for a calculation for correction of ionospheric propagation robust to differential errors linked to the local reception environment of the signals. Each channel comprises a code generator, a carrier phase generator, integrators, phase and code discriminators, a code phase numerically-controlled oscillator, a carrier phase numerically-controlled oscillator, carrier phase loop matched filtering means, and code phase loop matched filtering means. The receiver further including:
