This paper is the result of a masters thesis performed at Linköping University for Saab Bofors Dynamics in Linköping, Sweden. Attitude is defined as the orientation of a coordinate frame in reference to another coordinate frame. This is often referred to as three consecutive rotations, called roll, pitch and yaw (or heading). Attitude determination is generally performed using inertial navigation systems composed of gyros and accelerometers. These systems are highly accurate but are very expensive and experience a drift when used for a long period of time. The global positioning system, or GPS

GPS carrier-phase measurements from two GPS antennas can be used to calculate the heading of the baseline that can be drawn between the two antennas. An integer ambiguity problem has to be solved, and the system is called GPS attitude determination (GPSAD). This way of calculating the heading is cheaper than the traditional ways to do it, but it requires GPS reception.

Attitude determination involves the estimation of the orientation of a body (usually aircraft or satellite) with respect to a known frame of reference. It has important applicationsin areas spanning navigation and communication. There exist two main approaches for determining attitude using the Global Positioning System (GPS): (1) algorithms which determine attitude via baseline estimates in two frames, and (2) algorithms which solve for attitude by incorporating the attitude parameters directly into the state. For each approach, we propose an algorithm which aims to determine attitude in an e

A correlation between orientation and phase-detector output is proved, and it is concluded that with further work on algorithms and signal filtering, an attitude determination system could be made. As Quadrotors or ’drones’ are controlled by a system that could benefit by another reference system, accuracy of the phase-detector system is compared with the navigation systems currently used in drones.

The ability to determine the range and attitude between two satellites can be a challenging venture. It can be made more challenging when considering the use of such a system on a small satellite. Successful implementation of a small and low power range and attitude sensor could open potential doors to multiple small satellite constellations and formation flying maneuvers. After successfully demonstrating an electromagnetic docking system on a one-dimensional air track, it was determined that continued work into two and three-dimensional systems would require a more functional range and attitu

Thesis (PhD)--Stellenbosch University, 1995.<br>ENGLISH ABSTRACT: New advanced control techniques for attitude determination and control of small (micro) satellites are presented. The attitude sensors and actuators on small satellites are limited in accuracy and performance due to physical limitations, e.g. volume, mass and power. To enhance the application of sophisticated payloads such as high resolution imagers within these confinements, a multi-mode control approach is proposed, whereby various optimized controller functions are utilized during the orbital life of the satellite.

The Bistable Boom Dynamic Deployment (B2D2) experiment aims to successfully demonstrate the deployment of a 2 meter self-deployable boom in order to offer an efficient alternative for small satellites to conduct higher quality magnetic field measurements. The boom will be placed in a free falling unit, following the CubeSat standard. To obtain reliable results from the deployment, the tumbling rate of the free falling unit must be reduced to acceptable levels. Two cameras located in the free falling unit will record the boom deployment, meaning that they will need to be pointed in the opposite
