Integer ambiguity problem
Nettetover the whole n-dimensional space of integers. In order to tackle this problem, we first replace the whole space of integers by a smaller set of integers. This is the so-called ambiguity search space. It is in this local space that the search for the integer least-squares solution is performed. In the case of the GPS, however, this search NettetA possibly novel method is used to overcome the well known integer ambiguity problem, involving the Gram Schmidt orthogonalization procedure at one stage and a fast …

Nettetstructure of the integer ambiguity problem. In this paper, we show that those arguments are strengthened by the availability of GLONASS L2 phases. Although GLONASS does not complicate the integer problem, it does require that the receiver and antenna be calibrated for frequency-dependent delays. If such delays exist they NettetThe CISA Vulnerability Bulletin provides a summary of new vulnerabilities that have been recorded by the National Institute of Standards and Technology (NIST) National Vulnerability Database (NVD) in the past week.
