This study examined the contribution of previous knowledge, working memory, and operational and navigation Internet skills, to text comprehension in a lesson embedded in an e-learning course.
As new constellations become operational, global navigation satellite systems (GNSS) are expected to provide better positioning service in the fading environments (e.g., indoors, urban canyon, and flyover).
We examined the contribution of Internet operational and navigation skills, previous knowledge, and working memory capacity to expository text comprehension as a lesson within an e-learning course.
In synthesis, verbal comprehension, previous knowledge, and operational and navigation Internet skills contribute, solely and in interaction, to hypertext and more complex digital text comprehension Working memory capacity might also have a limiting role.
Hypertext and digital text comprehension studies found that previous knowledge, working memory (Amadieu & Salmerón, 2014; Burin, Kahan, Irrazabal, & Saux, 2013) and operational and navigation skills (Fajardo et al., 2016; Hahnel et al., 2016; OECD, 2011) contribute to digital text comprehension, and the effect of Internet skills depends on level of previous knowledge and working memory capacity.
Emmons, who succeeded Andrews as commander of GHQ Air Force, complained in his "Report on Annual Tactical Inspection", dated 28 July 1939, that because of the operational restriction, navigation training in the Air Corps had suffered.
However, the GNSS signal fades because of electron density gradients and irregularities in the ionosphere, decreasing the operational performance of navigation systems.
We conclude with a short summary of the new findings and their consequences on ionospheric monitoring and modelling for operational communication and navigation systems.
The plasma density irregularities are, for example, the biggest error source for global positioning system (GPS) signals during space weather events by causing a decrease in the operational performance of navigation systems (Forte and Radicella 2004).
These prior studies did not dissect the operational stages during navigation, nor did they isolate the type of distance that might have been represented.
