“…In literature, various GNSS-based AD satellite missions have been discussed namely GADACS (the GPS Attitude Determination and Control System) [59], SPARTAN (Station Power, Articulation, Thermal, and Analysis) [60], RadCal (Radar Calibration) [61], REX (Radiation Experiment) II [62], Gravity Probe B [63], UniSat (University Satellite) [64], Gyrostat [65], UoSat-12 (University of Surrey) [66] and AlSat-1 (Algeria Satellite) [67]. The equipment installed on satellites usually has tight constraints on its mass, volume and energy consumption.…”

GNSS-based Attitude Determination (AD) of a mobile object using the readings of the Global Navigation Satellite Systems (GNSS) is an active area of research. Numerous attitude determination methods have been developed lately by making use of various sensors. However, the last two decades have witnessed an accelerated growth in research related to GNSS-based navigational equipment as a reliable and competitive device for determining the attitude of any outdoor moving object using data demodulated from GNSS signals. Because of constantly increasing number of GNSS-based AD methods, algorithms, and techniques, introduced in scientific papers worldwide, the problem of choosing an appropriate approach, that is optimal for the given application, operational environment, and limited financial funding becomes quite a challenging task. The work presents an extensive literature survey of the methods mentioned above which are classified in many different categories. The main aim of this survey is to help researchers and developers in the field of GNSS applications to understand pros and cons of the current state of the art methods and their computational efficiency, the scope of use and accuracy of the angular determination.

“…One of the solutions is the use of standalone GPS receivers/antennas for determining the attitude. This technique has been explored in the past by various researchers, and different algorithms were given using the code and/or phase measurements of the GPS signal [3][4][5][6][7][8][9][10][11].…”

The attitude determination of nanosatellite has been performed in many satellite missions using different sensors like magnetometer, gyroscopes and sun sensors but the cost, weight and power requirements motivate the researchers for standalone GPS based attitude determination system. The attitude determination of the Cubesat projects can be obtained by using the code based measurements from at least three commercial- off- the- shelf (COTS) GPS antennas/receivers mounted on the surface of the satellite with known baseline measurements. Although the code measurements are not as accurate as the phase measurements, but it can give the accuracy of one degree that is sufficient for the experimental Cubesat projects. This research contribution presents the GPS code-based attitude determination algorithm while post processing the static test data and implementing the algorithm in MATLAB environment. The single-point positioning is used for determining the position of the Master antenna, and differential positioning is done to find the slave antennas' position and baseline coordinates. Finally, attitude is determined and compared using the least square and direct methods. Various GPS signal and system errors like ephemeris, clock. Ionospheric and Tropospheric errors along with satellite geometry are also calculated.
