AbstractWith the development of Global Navigation Satellite Systems (GNSS), the signal from more than 30 satellites of GNSS can be caught by a receiver in China at a time, which will provide conveniences for estimating instrumental biases of GNSS system. In this paper, instrumental biases of GNSS system have been firstly analyzed under different temperature conditions. The results show that instrumental biases are changed with the rapid change of temperature and the variation of instrumental biases can reach 12. 53 total electron content unit (TECU, 1 TECU= 10(16) el.m(2)). Furthermore, the change of instrumental biases is slow and about 1. 00 TECU under constant or room temperature. Based on the above experiments of instrumental biases, we have proposed a method of estimating GNSS instrumental biases for a receiver of multisystem. The method is named Triangle Decomposition and Difference Elimination (TDDE) method for single station and applied in analyzing GNSS data in Baoding during 2015-2017. Our analysis shows that TDDE is advanced in speed and independence for solving instrumental biases. The result obtained by TDDE in BeiDou Navigation Satellite System is better than that in GPS and GLONASS. Meanwhile, the instrumental biases corrected by TDDE are 2. 50-3. 00 TECU larger than those adjusted by Global Ionosphere Maps from Center for Obit Determination in Europe. In addition, the vertical TEC corrected by TDDE can clearly present diurnal variation, sunrise enhancement, semi-annual and annual variations, and equinoctial asymmetry of ionosphere TEC.
