Other Electronic Navigation Equipment SINS Radio Direction Finders SINS  (Ship’s Inertial  Navigation  System)  is  the  process  of  directing  the movements  of  a  rocket,  ship,  aircraft,  or  other  vehicle  from  one  point  to another,  based  on  sensing  acceleration  of  the  vehicle  in  a  known  spatial direction  with  the  aid  of  instruments  that  mechanize  the  Newtonian  laws of  motion,  and  integrating  acceleration  to  determine  velocity  and position. SINS  is  an  accurate,  all-weather,  dead  reckoning  system.  It  employs gyroscopes,  accelerometers,  and  associated  electronics  to  sense  turning rates  and  accelerations  associated  with  the  rotation  of  the  Earth,  and  with ship’s  movement  relative  to  the  surface  of  the  Earth. Radio  beacons  were  the  first  electronic  aid  to  navigation.  The  basic value  of  the  radio  beacon  system  lies  in  its  simplicity  of  operation  and its  relatively  low  user  costs,  even  though  the  results  obtained  may  be somewhat  limited.  The  Radio  Direction Finder  (RDF)  is  a  specially designed  radio  receiver  equipped  with  a  directional  antenna.  The antenna  is  used  to  determine  the  direction  of  the  signal  emitted  by  a, shore  station,  relative  to  the  vessel.  A  radio  beacon  is  basically  a short-range  navigational  aid,  with  ranges  from  10  to  175  nautical  miles. Bearings  can  be  obtained  at  greater  ranges,  but  they  are  usually  of doubtful  accuracy  and  should  be  used  with  caution.  When  the  distance to  a  radio  beacon  is  greater  than  50  miles,  a  correction  is  usually  applied to  the  bearing  before  plotting  on  a  Mercator  chart.  These  corrections,  as well  as  information  on  the  accuracy  of  bearings,  plotting,  and  other matters,  are  contained  in  DMA  publication  117,  Radio  Navigational Aids. 8-51
