“…where is the measured directional cosine of unit vector (radius vector connecting the reference antenna and the satellite) with respect to antenna base for SV i (space vehicle) On the other side, with the known Cartesian coor dinates of reference antenna in Greenwich frame (from GNSS), orientation matrices and calculated in IMU, and known coordinates of SV i , one can calculate the directional cosines of unit vector in IMU frame [20] (similarly to the situation when IMU is not turned with respect to object frame [20]) and then calculate the directional cosines of unit vec tor with respect to bases…”

“…The known measurements of navigation data are used as input for the filtering problem [20,21]: differ ence between the calculated (IMU) and measured (GNSS) raw navigation parameters (pseudoranges ρ i and radial velocities for each satellite) or complete navigation solutions (position coordinates and components of linear velocity vector ).…”

The paper considers determination of attitude parameters, including true heading, by an inte grated orientation and navigation system (IONS) comprising MEMS based inertial measurement unit (IMU) and multiantenna GNSS receiving equipment. IONS generates orientation solution using phase data from two antenna GNSS module with antenna base about the wavelength of the satellite signal at carrier fre quency. The system algorithms and errors are studied. IMU and GNSS antenna base are subjected to modu lating rotation. Effectiveness of using GNSS phase determinations for estimating heading errors with a short rotating antenna base is investigated. The system experimental sample uses IMU based on STIM300 Senso nor MEMS sensors (Norway), navigation and phase measurements by GNSS receivers 1K 181 by Russian Institute of Radionavigation and Time (Russia). The results obtained in bench tests are presented.
