Note: Web mode focuses on settings, you can set how many sets of data are logged on and off, and ftpmode
focuses on data export, so data export is recommended using ftp mode or Type-C data line export.
5.4 Static accuracy test
Static measurement accuracy refers to the degree to which the static measurement baseline vector results of
the device under test conform to the known baseline vector (horizontal and vertical components).
Static measurements are tested on outdoor reference points. Here are the steps:
(1) Short baseline fast static measurement (around 3km)
The two base station receivers are located on two reference points with wide field of view, with a distance of
about 3km between the two points. Save the original data in the RINEX data format. The height angle is set to 10o,
the sample rate is set to 10s, the test time is 40min, and two periods of time are observed.
(2) Medium-length baseline static measurement (around 10km)
The two base station receivers are located on two reference points with wide field of view, about 10 km
apart. Save the original data in the RINEX data format. The height angle is set to 10o, the sample rate is set to 10s,
the test time is 2h, and three periods of observation are observed.
(3) Medium-length baseline static measurement (around 30km)
The two base station receivers are located on two reference points with wide field of view, about 30 km
apart. Save the original data in the RINEX data format. The height angle is set to 10o, the sample rate is set to 10s,
the test time is 4h, and three periods of observation are observed.
(4) Medium-length baseline static measurement (around 50km)
The two base station receivers are located on two reference points with wide field of view, about 50 km
apart. Save the original data in the RINEX data format. The height angle is set to 10o, the sample rate is set to 10s,
the test time is 8h, and three periods of observation are observed.
The collected static data can be downloaded via ftp or Type-C.
Evaluation method: Using random post-processing software, the observation data is processed, the
combination of Beidou/GPS dual system under different baseline lengths, the static measurement level of
single Beidou and single GPS, the vertical measurement accuracy, and the baseline repeat check are carried
out.
