Ric refraction error, the of Ionospheric Refraction three. HighAccuracy Correction Technologyionospheric range error due to refraction mainly consists of delay and bending effects. For the Sband radio wave, As is of elevation the target is higher refraction error, the ionospheri when the anglesimilar to of thetroposphericthan 3 , the bending effect is Difelikefalin Data Sheet usually ignored, and the ionospheric refraction error isand bending effects. For the Sban refraction primarily incorporates delay in the ionospheric delay [25,26]. A functional relationship exists in between the ionospheric delay Riono and electron content in the angle path, TEC: the ionospheric of elevation on the target is larger than three the bending ef as well as the ionospheric refraction 40.3 TECis from the ionospheric delay Riono = error (11) frelationship exists among the ionospheric delay and elec For those targets with an orbit higher than 2000 km, the radiowave signal almost ionospheric path, : passes by means of the m-3M3FBS Epigenetics ionosphere area. The important to the ionospheric refraction error could be the totalelectron content with the ionosphere inside the target path TEC. The calculation technique is usually discovered inside the relevant literature and will not be repeated right here [27]. The range error correction technique is shown in Figure 3. This study assumes that when the variety among Target O plus the nearby satellite satisfies particular situations inside a period iono two of time (to ti ), the outcome of IPPo VTEC at IPP from the target towards the receiver (recorded as VTEC IPPO ) is equal in size to IPPi VTEC at IPP from Satellite i for the receiver (recorded as VTEC IPPi ). VTEC IPP_O (SO , O , t0 ) = VTEC IPP_i (Si , i , ti ) (12)R=40.three TEC fFor these targets with an orbit higher than 2000 km, the radio passes through the ionosphere location. The crucial towards the ionospheric refrac electron content material of your ionosphere in the target path . The calcul located within the relevant literature and can not be repeated right here [27]. The variety error correction strategy is shown in Figure 3.

The angular diameter is integrated with time information and facts but is not a fixed grid within the space. Inside the selfadaptive grid process, the satellite nearest for the target (that is, the satellite with all the smallest angular diameter towards the target ) is selected. The electron content inside the path is calculated 1st, using.
