Integer l1 ambiguity solution

Nettet25. apr. 2024 · In the final step, the integer ambiguity solution is used to correct the float baseline solution. This solution is referred to as the ‘fixed solution’. If one may neglect the randomness of the integer ambiguity solution, the fixed baseline solution will have a much higher quality than the float baseline solution.
