Distance from earth to gps satellite? Navigation satellites move around Earth at an altitude of about  1,243 miles to 22, 223 miles and at about the same speed of  rotation. These satellites are in what is calle â¦ d Medium-Earth  orbits (MEO).
When aerating your lawn, it is best to aerate on a day where the temperatures are milder and the soil in a moist condition, which will make the aerating process much easier. Aerating wet soil can be a real nuisance due to the fact that the plugs will get stuck in the hollow tines and can further compact you soil.
Aeration, or core removal, performed up to twice a year may be necessary to combat the compaction process. You should not rake the lawn after aeration unless you are breaking down the removed cores. Aeration encourages root spread for easily accessible moisture, nutrients and air by core removal. Using a hand or power tool, 3-inch long cylindrical soil plugs are physically pulled from the ground at 3-inch intervals.
