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.
Â· If the lawn is covered 50% or less with healthy fescue, use a verticutter (sometimes called a dethatcher). Adjust the verticutter blades to just touch the top of the soil. Â· If the lawn is covered 50% or more with healthy fescue, use a core aerator. Stop when you have 10 or more aerator holes per square foot. Â· Just before seeding, lower your mower one notch below your normal mowing height and mow the lawn.
