Magnetometers are an integral part of attitude determination system for the low-Earth orbiting small satellites as they are lightweight, inexpensive and reliable. Yet using magnetometers for attitude determination is not straightforward because of the sensor errors. These errors limit the overall achievable attitude determination accuracy. Thus far different methods to cope with magnetometer errors and calibrate the magnetometers have been proposed. A new research field is the specific errors for magnetometers onboard the small satellites and their time-variation characteristics. In accordance, algorithms which consider also the time-varying error terms are proposed. This paper reviews the recent calibration algorithms for small satellite magnetometers. The survey mainly covers batch and recursive estimation algorithms which are capable of estimating the time-varying magnetometer error terms. It presents the foundation of each algorithm and covers issues about the algorithm design, application and performance. In the end possible directions in this research field are briefly discussed.

A Survey of Calibration Algorithms for Small Satellite Magnetometers Söken, Halil Ersin (2017-01-01) Magnetometers are an integral part of attitude determination system for the low-Earth orbiting small satellites as they are lightweight, inexpensive and reliable. Yet using magnetometers for attitude determination is not straightforward because of the sensor errors. These errors limit the overall achievable attitude determination accuracy.

Enhancement of the reliability of MEMS shock sensors by adopting a dual-mass model Fathalilou, Mohammad; Soltani, Kamran; Rezazadeh, Ghader; Ciğeroğlu, Ender (Elsevier BV, 2020-03-01) MEMS shock sensors are widely used with applications ranging from aircraft to electrical measurement systems. They are designed to operate at the shocks above a predefined threshold level. The conventional single-mass switches may lose their reliability at shock levels smaller than the threshold, if experience smaller unwanted pulse duration. This paper has proposed a dual-mass switch with auxiliary mass-spring attached to the main system which increases the reliability of the sensor against the unwanted pu...
Comparing the probing systems of coordinate measurement machine: Scanning probe versus touch-trigger probe Bastas, Ali (Elsevier BV, 2020-05-01) An increasing level of research is focalising around the Coordinate Measurement Machine (CMM) as an important dimensional inspection instrumentation, that is utilised in a wide range of industrial metrology applications with its high precision measurement capabilities, flexibility and high measurement speed. The key functional section of the CMM is the probing system, that enables capturing of spatial coordinate data along measurement surfaces. This research compared the measurement performance parameters (...
A new wireless asynchronous data communications module for industrial applications EGE, Yavuz; Sensoy, Mehmet Gokhan; Kalender, Osman; Nazlibilek, Sedat; Citak, Hakan (Elsevier BV, 2013-10-01) All the sensors such as temperature, humidity, and pressure used in industry provide analog outputs as inputs for their control units. Wireless transmission of the data has advantages on wired transmission such as USB port, parallel port and serial port and therefore has great importance for industrial applications. In this work, a new wireless asynchronous data communications module has been developed to send the earth magnetic field data around a ferromagnetic material detected by a KMZ51 AMR sensor. The ...
Thermodynamical parasitic forces in high precision accelerometers on board of a drag-free satellite Karslıoğlu, Mahmut Onur (Elsevier BV, 2004-03-15) High-resolution accelerometers and gradiometers on board of drag-free satellites are employed in different scientific space missions. The applications range from experiences in fundamental physics to the earth's observations associated with the precise orbit determination of low earth's orbiter (LEO) particularly in context with the autonomous navigation and the determination of the short wavelength part of the earth's gravity field which is an important topic of satellite Geodesy. A satellite flying drag-f...
