Samenvatting

In the article: "Base Line Performance of the Low Cost LORADD SP Receiver" also published in "Advances in military navigation technology" the authors discussed the basic performance of the LORADD SP receiver. One of the conclusions was that eLoran in its baseline configuration cannot serve as a back up for GNSS. In this article they will explore the possibilities to improve the results. Therefore they will first argue why further research is necessary. Then the authors will analyse the observation equation of eLoran and concentrate on improvement on the level of observations. Finally they will outline improvements on the level of positions, for which no measurements have currently been made.
