Concept for a time-code signal assisted single-shot receiver

This paper presents a novel concept for a GNSS receiver for mobile devices based on the single-shot receiver concept. In comparison to the common single-shot receiver the amount of computational hardware is significantly reduced by an estimation of the time of signal reception. This allows an a-priori estimation of the code-phase of the satellites in view. The synchronisation to the time code signal must be better than 1 ms for GPS-In-Orbit-Vehicles(IOVs) to take effect which is here realized by using the german DCF77 signal with an precision of 250 ns under ideal circumstances. Regarding all uncertainties in time and the amount of signal processing power required for the time synchronisation the computational effort for the advanced single-shot receiver can be cut down by a factor of two.
