        abstract = {Using  magnetic  compass  sensors  in  angle  measurements  have  a  wide  area  of  application  such  as positioning,  robot,  landslide,  etc.  However,  one  of  the most  phenomenal  that  affects  to  the  accuracy  of  the magnetic  compass  sensor  is  the  temperature.  This  paper  presents  two  thermal  stability  schemes  for  improving  performance of a magnetic compass sensor. The first scheme  uses the feed forward structure to adjust the angle output  of  the  compass  sensor  adapt  to  the  variation  of  the  temperature.  The  second  scheme  increases  both  the temperature  working  range  and  steady  error  performance  of  the  sensor.  In  this  scheme,  we  try  to  keep  the  temperature  of  the  sensor  is  stable  at  the  certain  value  (e.g.  25 o C)  by  using  a  PID  (proportional-integral-
derivative) controller and a heating/cooling generator. Many experiment scenarios have implemented to confirm 
the effectivity of these solutions.}
