2. GPS

3. A. Definition of GPS The Global Positioning System (GPS) is a space-based global navigation satellite system that provides reliable and time information in all weather and at all times and anywhere on or near the Earth when and where there is an unobstructed line of sight to four or more GPS satellites.

4. B. The Basic of GPS • The Basics of GPS to determine the position is measuring delay time transmision a signal by receiver, cross with the signal velocity. So we’ll get a receiver distance relative toward the satelite.To be found X, Y, and Z coordinate, receiver need monitoring from three satelites, and once observasion from forth sateleiteneeded the acurate prediction.

5. C. GPS ELEMENT • GPS has 3 parts : Space Segment, The User Segment, and The Control Segment. • Space Segment dari sistem terdiri atas satelit GPS. Space vehicles (SVs) ini mengirimkan signal radio dari angkasa. • GPS control, atau ground segment terdiri atas stasiun monitor tanpa manusia berlokasi di sekeliling bumi. • GPS User Segment terdiri atas receiver GPS dan komunitas pengguna. Receiver GPS dapat dibawa atau di-instal pada pesawat, tank, kapal selam, mobil, dan truk. Receiver ini mendeteksi, mendekode, dan memroses signal satelit GPS.

7. D. GPS Receiver • GPS Receiver should be detection and converting signal that have been transmitted from among satelite in useful measurment. • GPS Receiver converting signal SV to be position, velocity, and estimation time. Four satellite needed for measuring forth dimension X, Y, Z (position) and time. GPS Receiver is used for navigation, positioning, time dissemination, and other research.

8. E. GPS DATA • Format Message Satelit GPS Reciever that usually recently used commonly is all-in-view, in the meaning it tries searching among satellite with the continous view. Receiver shown the navigation message continously, searching the data content change subframe 1, 2, or 3.

9. F. usefulness of GPS in a specific field • GPS in Military This equipment carried by the infantry, placed on each vehicle to facilitate the coordination of combat maneuvers and tactics used. With the help of GPS, the position of each unit can be known precisely so that it will facilitate preparation of combat strategy. And also GPS used to determine its position and determine the direction toward the enemy. 

10. Sailing and Aviation  At sea GPS also plays an important role for sailors and fishermen for their boats do not get lost and problems that have faced for hundreds to determine precisely the position finally solved. In the event of accident or emergency conditions the use of GPS will be helpful for a ship can be found quickly. And also for aviation or plane flight, GPS used for monitoring the determining of position and direction so that the entry into restricted airspace  and also for heightness. • Public Service In many countries GPS is commonly used by police officers, firefighters, rescue squads or so in the event a matter that requires quick handling, it can be immediately known which units are in a position closest to the scene. • Commercial  In addition to things that are not commercially as above GPS is also used for commercial purposes such as courier services, taxis and other services will help to improve the quality of service from the services concerned. 

11. Mapping and Survey  For areas that have not been carefully mapped, GPS can help determine the exact location (although unable to show map) so that the people conducting the survey will not be lost. With the help of GPS is also a person can make a map of an area more easily.  • Application There is now a lot of manufacturers of GPS receivers, nearly all mobile phone manufacturers also make a GPS system, several other companies only focus on GPS systems like the Magellan, Garmin, etc.. In addition to the GPS receiver based on the hardware (built-in software), there is also a GPS receiver based on the hardware and software.

12. COMPASS

13. A. DEFINITION Compass is the direction pointing device used to determine magnetic north. Due to the nature magnetic, a compass needle would point north-south direction (if not affected by magnetic forces other than the Earth's magnetic).

14. B. inclination Inclination is the inclination compass needle caused by differences in geographic location of a region on the earth's poles. Heeling angle will be almost 0 (horizontal) when we are near / around the equator, and large increases when approaching the poles of the earth

15. C. deCLination Declination is the angle formed by the direction of the compass north and true north (geographic north) as a result of not berimpitnya point magnetic north and geographic north point. The amount of declination sector in a region generally indicated on the topographic map area.

16. D. The parts of geology compass

17. E. The usefulness of compass Example use of the compass directly in the field as follows: i. River navigationii. Reading mapsiii. Taking an angle direction, etc.

18. F. Strike & Dip direction Strike is the direction of the spread rock degrees. Which can notice where the spread plains of rock in the fields.

19. g. strike • Look for the rock area that rather flatten (you can use the clipboard) • Look for a rather flat area of rock (for a flat, you can use the clipboard as a base board) • Attachthe E (East) into the rock bodies on the field with compass arm in the direction of strike.

20. Slide it until the air bubble at the level of rounded (bull's eye level) right in the middle. • Read the indicated degrees north needle (is a needle that points north when you're facing north)

21. H. dip • Attach the W (West) into the field of rock bodies with compass compass arm perpendicular strike.

22. On the behind of the compass is a small lever to rotate the tube level (clinometer level). Rotate the tube until the bubble level right in the middle. • Read the indicated degree / clinometer degrees (remember, the maximum degrees dip 90 degrees).

23. I. Azimuth • Compass held with the left hand waist-high • Compass is made horizontal (with the help nefo eye beef) and maintained during the observation • The slope of an open set of approximately 135 ° facing forward and the sighting arm is opened horizontally with the peep sight is established • Agency played in such and coincides with the end of the sighting arm and the center line on the mirror. It is important to remember that not only played the hand with a compass but the whole body. • Read the northern compass needle, after the needle is not moving. The result of reading is the direction in question. • Kompasdipegangdengantangankirisetinggipinggang • Kompasdibuat horizontal (denganbantuannefomatasapi) dandipertahankanselamapengamatan • Kemiringandiaturterbukakuranglebih 135°menghadapkedepandan sighting arm dibuka horizontal dengan peep sight ditegakkan • Badandiputarsedemikiandanberimpitdenganujung sighting arm dangaristengahpadacermin.
