ASSIGNMENT  1 Textbook  Assignment: “Surface  Navigation  Systems,”  chapter  1,  pages  1-1  through  1-19;  and “Tactical  Air  Navigation,”   chapter 2, pages 2-1 through 2-9. 1-1. 1–2. 1–3. 1–4. 1-5. Tactical  navigation  is  directly concerned with maneuvering the ship in navigable waters. 1. True 2. False Estimating  ship’s  position  between known  navigational  points  or  fixes is known as 1. ship maneuvering 2. dead  reckoning 3. ship  reckoning 4. dead maneuvering Radio  navigation  consists  of  which of  the  following  categories? 1. Sub-space  systems 2. Space–based  systems 3. Terrestrial  systems 4. Both 2 and 3 above One  of  the  characteristics  of  dead reckoning is that the accuracy of the  estimated  position  never exceeds  the  navigation  method  used to obtain the last fix. What happens to the accuracy of the estimated  position  over  time? 1. It  increases 2. It  decreases 3. It stays the same 4. It  fluctuates Referring  to  landmarks  with  known positions  on  earth  describes  which one  of  the  following  navigation methods? 1. Celestial 2. Charting 3. Dead  reckoning 4. Piloting 1 1-6. 1-7. 1-8. 1–9. 1-10. Which  of  the  following  actions required  to  determine  position  in piloting  is/are  not  required  in electronic   navigation? 1. Seeing  the  landmarks 2. Determining  the  ship’s  heading 3. Having the ship on a dead reckoned  course 4. Both 2 and 3 above According  to  the  1992  Federal  Radio Navigation  Plan,  which  of  the following  systems  will  become  the primary  reference  navigation  system for  surface  ships? 1. LORAN 2. OMEGA 3. NAVSTAR 4. TACAN LORAN takes advantage of what radio signal   characteristic? 1. Constant  amplitude 2. Constant  velocity 3. Constant  phase 4. Constant  volume OMEGA  is  a  hyperbolic  phase— difference  measuring  system  that compares the phase angle of two or more  radio  signals  synchronized  to what  device  or  factor? 1. A common receiver 2. A  common  signal  shift 3. A common time base 4. A  common  transmitter Which  navigation  system  continually computes  the  latitude  and  longitude of  a  ship  by  sensing  acceleration? 1. NAVSTAR 2. OMEGA 3. MILSTAR 4. SINS
