Embodiment 1

[0033] refer to Figure 1-2 , a navigation positioning method based on electronic information, comprising the following steps:

[0034] S1: Data collection, monitor and collect the mean error and mean square error of the ground plane positioning error; the mean error and mean square error of the east-west (longitude direction) deviation, the mean error and mean square error of the north-south (latitude direction) deviation, and estimate the positioning error The probability distribution of , the analysis shows that;

[0035] S2: data processing, processing the collected data obtained in S1;

[0036] S3: base station, collect the data obtained by S2 through the distribution of base stations;

[0037] S4: GPS positioning, transfer the data obtained in S3 to the GPS positioning system for processing, GPS positioning compares the new data received by S3 with the pre-stored old data, if there is any change, the GPS positioning system will overwrite the old data with new data ; ...

Embodiment 2

[0042] A navigation and positioning method based on electronic information is basically the same as Embodiment 1. Furthermore, data processing is to extract valuable information from a large amount of raw data, that is, the process of converting data into information, mainly for the input Various forms of data are processed and sorted, and the whole process of evolution and derivation of the collection, storage, processing, classification, merging, calculation, sorting, conversion, retrieval and dissemination of the collected data, the result of the low sampling rate is the restored signal The frequency of the signal looks different from the original signal. This kind of signal distortion is called aliasing (alias). The frequency of the mixing frequency that appears is the absolute value of the difference between the frequency of the input signal and the nearest integer multiple of the sampling rate. The result of the sampling will be Signals below the Nyquist frequency (fs / 2=5...

Embodiment 3

[0045] refer to figure 2 , a navigation and positioning method based on electronic information, which is basically the same as Embodiment 1, and furthermore, GPS positioning includes the following steps:

[0046] S41: Data separation, used to distinguish whether the data-generated image and the real image of the data belong to the same category;

[0047] S42: Data discrimination, used to distinguish whether the generated data image is at the same location as the collected data location;

[0048] S43: Data generation, used to distinguish whether the newly collected data images are close enough to the image features in the database;

[0049] S44: data coverage, when the gap between the newly collected data images and the image features in the database is too large, the new collected data is covered by the old data;

[0050] Data classification is used to classify different regions id1 and region id2, and compare the image features of region id1 and region id2 through data. Th...

Abstract

The invention discloses a navigation positioning method based on electronic information, and belongs to the technical field of riverway sludge recycling devices. The navigation positioning method based on electronic information comprises the following steps of: S1, data acquisition, which is implemented by monitoring mean deviation and mean square error of acquired ground plane positioning errors, mean deviation and mean square error of the east-west (longitude direction) deviation and mean deviation and mean square error of the south-north (latitude direction) deviation, speculating the probability distribution of positioning errors, and carrying out analysis for indication; S2, data processing, which is implemented by processing the data acquired in the step S1; and S3, arranging base stations to collect the data obtained in the step S2 through distribution of the base stations; According to the navigation positioning method based on electronic information, when the feature difference between the newly acquired data image and the image in the database is too large, the newly acquired data covers the old data, thereby saving the workload of workers for investigation and data acquisition of road segment changes of part of regions.

Description

technical field [0001] The invention relates to the technical field of river channel silt reuse devices, in particular to a navigation and positioning method based on electronic information. Background technique [0002] During the continuous tracking of GNSS satellites, the short-term interruption or loss of lock of the satellite signal due to occlusion will lead to the reinitialization of the PPP filter, and the ambiguity parameters cannot be restored to the correct integer ambiguity before the signal interruption in a short period of time, thus As a result, the observation epoch in the process of PPP re-convergence cannot obtain centimeter-level high-precision PPP fixed solutions, and the actual positioning accuracy is only meter-level or decimeter-level. At present, the application of PPP technology often requires a relatively open observation environment to avoid the interruption of satellite navigation signals, but this practice will greatly limit the usability of PPP ...
