  • Method and device for receiving a degraded radionavigation signal
    Patent number: 7826518
    Abstract: The invention relates to a method of receiving a radionavigation signal. Over a first determined time correlations of the sampled signal received are calculated with a locally generated code of period T. The signal is received and the code is shifted with respect to one another from one correlation to the next correlation. Over the determined time, the signal is shifted from one correlation to the next, the code being fixed.

  • Automatic decorrelation and parameter tuning real-time kinematic method and apparatus
    Patent number: 7663539
    Abstract: A method of and computer-readable medium containing instructions for high accuracy, reliable position determination. The ADAPT-RTK Technology (Automatic Decorrelation and Parameter Tuning Real-Time Kinematic technology) is described using an innovative decorrelation algorithm to decorrelate the correlation between L1 and L2 measurements through a functional model and a stochastic model reducing the impact on performance of distance dependent biases.
