Webof satellite ephemerides, effects of ionosphere and troposphere are almost eliminated by forming DD (double-difference) measurement equations. With a medium length baseline under 100 km, in particular ionosphere effects are hard to be canceled by DD. In this case, dual-frequency measurements are often used to eliminate the ionosphere effects. WebBack Original Calculating Position from Raw GPS Data (2024) grants and treasury department
