The string dynamics in de Sitter spacetime is integrable due to the associated linear system. We start from an exact string solution $q_{(0)}$ and the associated solution of the linear system $\\Psi^{(0)} (\\lambda)$, and we construct a new solution $\\Psi(\\lambda)$ differing from $\\Psi^{(0)}(\\lambda)$ by a rational matrix in $\\lambda$ with at least four poles $\\lambda_{0},1/\\lambda_{0},\\lambda_{0}^*,1/\\lambda_{0}^*$.
