Abstract

All strongly region GPS  signals,  which  in  turns  affect  positioning.  This  arises  from  the  fact  that,  the  country  is  characterised copious due  to  its  high  humidity,  thus  regarded  as  a  ‘tropical  rainforest’.  This  paper  presents  a  study  conducted  in  Southern  Malaysia  near  the  equator,  to  model  two  and  half  (21/2)  years  meteorological  parameters;  temperature,  pressure  and  relative  humidity  from  four  weather  stations network MetMOD nonparametric  trend  statistics  used  to  analyse  trends  at  each  of  the  GPS  network  reference  station. reveals  that,  temperature  agrees  with  the  observed  data  at  an  average  mean  difference  of  0.1620C pressure  at  an  average  mean  difference  of  about  0.179  hPa  and  RMSE  of  0.251  hPa;  while  relative results  show  that;  relative  humidity  showed  most  of  the  upward  and  downward  trends,  having  more  effects  on  stations  with  small  ellipsoidal  height;  whereas,  pressure  has  more  effects  on  stations at low latitude.
