Time Scales Comparisons Using Simultaneous Measurements in Three Frequency Channels
Original language description
This paper describes the design of optimal methods for processing the results of measurements in several frequency channels based on the Best Linear Unbiased Estimation (BLUE). The optimal estimate was derived for a number of elementary models (no ionospheric delay, first-order ionospheric delay, first- and second-order ionospheric delay), and the contribution of using measurements in three frequency channels was evaluated compared to procedures used up to now. We show that the optimal estimates are insome cases equal to already used linear combination of measurements (e.g. L3P) and thus these classical procedures can be considered optimal. We confirm the fact that the ionospheric free solution is always redeemed with significant increase of impact ofrandom errors. The impact is increased by factor of three concerning the measurements in two frequency channels compared to measurement in a single frequency channel. We show that improvement of 15 % can be achieved if measurements in th
