<p>A method of reducing the impact of space vehicle clock frequency jumps on the device for position detection includes the steps of:
(i) Checking
- whether navigation signals received from a sufficient number of space vehicles of a first group of space vehicles provided with clocks in which no frequency jumps occur are available, and
- whether the integrity risk calculated with the navigation signals received from the space vehicles of said first group of space vehicles is equal to or lower than a predetermined acceptable maximum integrity risk;
(ii) If the conditions are not fulfilled, iteratively adding navigation signals received from a space vehicle of a second group of space vehicles provided with clocks in which frequency jumps can occur to said navigation signals received from the space vehicles of said first group of space vehicles until the integrity risk calculated for all combinations of the navigation signals received from the space vehicles of said first group of space vehicles together with the integer sub-set of said second group of space vehicles is equal to or lower than a predetermined acceptable maximum integrity risk.</p> |
