Also note that at certain longitudes, there is a small transverse component of the equatorial earth field which can be significant. All of these considerations should be taken into account when desi gning the spacecraft. To correct a positive yaw error, the curren t should be reversed. As with any device, there are operational considerations in order to try to minimize errors and inefficiencies. Interference may become especially important since the expected magnetic field is on the order of nano-Tesla.
Transponders are also susceptible to magnetic fields.
The torquers may be turned off. Depends on attitude needs. Since the torquer on IS-K is skewed, there is an effect on the pitch axis. Kluwer Academic Publisher, 1995.
