Description
Technical field
The present invention relates to the satellite navigation field, relate in particular to a kind of detection method, Apparatus and system of Ionosphere Residual Error disturbance quantity.
Background technology
To GPS (Global Positioning System; GPS) the ground remote measurement is used; TEC (Total Electron Content; The ionosphere total electron content) be to make the satellite radio electric wave in communication process, produce the main factor of signal delay, accurately predicting and to deduct the ionosphere delay effect be that Ground-Based GPS atmosphere vapour telemetry can be able to practical prerequisite.
When distance is greater than 100km between the GPS survey station; Can be through adding CODE (the Center for Orbit Determination in Europe; Orbit determination center, Europe) GIM that provides (Global Ionosphere Map, Global Ionospheric analysis and prediction product) model comes the cancellation ionospheric error; GNSS (Global Navigation satellite Systems; GPS) IGS of International Service Organization (The International GNSS Service) is through Ground-Based GPS reference net data processing and analytic centres such as CODE under it; GIM openly is provided, for the activity of global atmosphere ionosphere provides effective monitoring, forecast and service every day.The GIM model is the Global Ionospheric model, and this model is to set up according to a large amount of actual observed values, and overall accuracy is fine, but some the irregular variations in the ionosphere can smoothly be fallen, and is difficult to from model, obtain reflection.
Present a kind of way is the Treatment Analysis that the Bernese software of the uranology research student of employing Switzerland Berne university development carries out the Ground-Based GPS data; To obtain relevant GPS survey station precision be millimetre-sized initial coordinate through analyzing long-time sequence Ground-Based GPS observation data, adopts L then
4The calculation method of linear combination is introduced the CODE-GIM data simultaneously, calculates the ionosphere RO (Residual Observation, residual error disturbance observed quantity) of single GPS survey station to single satellite.
Double-frequency GPS receiver is through gps satellite carrier phase signal L
1And L
2Linear combination L
3Come the cancellation ionosphere delay, but single-frequency GPS receiver is because of having only the carrier wave can't the ionospheric influence of cancellation, ionospheric error just becomes largest error source, and much larger than the tropospheric delay error; So use single-frequency Ground-Based GPS receiver just to be difficult to extrapolate the troposphere total delay separately.When distance between the GPS survey station during, can come the cancellation ionospheric error through the Global Ionospheric GIM model that adds European orbit determination center C ODE and provide greater than 100km; When distance was less than 10km between survey station, the ionosphere characteristic correlativity between survey station was strong, therefore can be through the method cancellation ionospheric error of two differences; But when distance between survey station was tens kilometers, ionosphere characteristic correlativity was less between standing, and can't use the method for two differences to eliminate, and also can't be eliminated by the GIM model.
Therefore, Rocken equals the regional meticulous ionosphere correction method (being the HiRIM method) that has proposed with the foundation of linear modelling method in 2000, is the technology of tens kilometers receiver antenna place ionospheric error to eliminate stop spacing.This technology is tried to achieve the residual error of the two difference in (stop spacing is less than tens kilometers) all double frequency stations observed reading in the zone earlier through Bernese software; The Theoretical Calculation that equals to propose in 2000 according to Alber then obtains the Ionosphere Residual Error disturbance observed quantity RO on the oblique path of wall scroll; At last just can utilize the method for linear fit to obtain the ionospheric corrections model based on CODE-GIM, this correction model and CODE-GIM model can merge the high-resolution HiRIM model of generation.The HiRIM model can be eliminated ionosphere delay error well, makes single dual-frequency receiver mix to arrange net the idea of monitoring atmosphere vapour to be achieved.
