Abstract: | If accurate first-order corrections for ionospheric delay are applied to VHF ranging signals, the second-order terms become dominant. Only with abnormally large values of ionospheric electron content do the second-order terms lead to serious errors, however. Since these terms can be estimated to within 10 percent, further correction can lead to very small position errors. |
