[. . . ] If it takes more time than those times described above, the unit is receiving GPS radio waves from satellites due to buildings, trees, etc. , in the way. Change the shooting location or wait until the satellites move to more favorable position. 2-3-2 Confirming a Location Calculated You can confirm the location currently calculated on the GPS INFORMATION window displayed on the viewfinder when recording or playing back GPS data. Displaying the GPS INFORMATION window Set the STATUS GPS item to ON on the SET STATUS page of the OPERATION menu. Displaying the GPS INFORMATION window on the viewfinder Push the STATUS ON/SEL/OFF switch on the camcorder upwards the ON/SEL side. Each time you push it up, the window displayed changes. Push it up repeatedly until the GPS INFORMATION window appears. For several seconds, the GPS INFORMATION window is displayed. Note Since serial communication is used for the GPS communication between the unit and computer, communication delay is theoretically generated. 2-8 Chapter 2 Using GPS Data (When Using an HKDW-704) Thus, if you are shooting while walking, an error between the movement in the image and the shooting location displayed using mapping software may be generated. This depends on the type of mapping software you are using. GPS INFORMATION window 2 Item LATITUDE LONGITUDE ALTITUDE CALC REAL TIME ZONE Contents Displays the latitude of the calculated location. Displays the longitude of the calculated location. Displays the altitude of the calculated location. Displays the date when the calculation was done. b) Displays time difference. a) When the unit completes calculating a location successfully, using the distance from three satellites, the time is displayed. Since it cannot perform another calculation immediately after it has completed on calculation, this indication stops at that time. When the unit can start another calculation, the indication starts advancing from that time. When a calculation is done correctly, the CALC time is later than the REAL time by 1 second. Note The same time as the REAL time is displayed as the CALC time during play (Continued) back. Chapter 2 Using GPS Data (When Using an HKDW-704) 2-9 b) When the unit has received data from one or more satellites, the correct current time is displayed. This time matches that of the GPS clock. In any other case, the time of the built-in crystal clock is displayed. 2 Note During playback, the calculation time recorded on the tape is displayed instead of the current time. Notes · While shooting, be sure to confirm that the latitude, longitude, altitude and calculation time are displayed. Also, the difference between the calculation time and the current time is one second. If it is larger than 1 second, it means that the unit is not receiving GPS data from satellites properly. · The date is displayed in UTC time display mode. Thus, the date display is different from your local time by the time difference appropriate to your location. 2-10 Chapter 2 Using GPS Data (When Using an HKDW-704) Displaying the GPS data reception status on the viewfinder Setting the DISP GPS item to ON on the VF DISP 2 page of the OPERATION menu allows the unit to display the GPS reception status on the regular shooting window of the viewfinder. Reception status of the GPS data 2 Number of x displayed 4 3 2 1 or not displayed Reception status Receiving data from four satellites. Not receiving GPS data. When two to four x are displayed while shooting, the unit calculates the location. [. . . ] GDOP is calculated fixing aim to such a drift that satellites to be used for calculating a location are placed against the location to be calculated with less offset. The larger the value, the larger calculation error is. The GPS receiver decides the best combination of satellites to be used based on the GDOP value to obtain precision. A-10 Appendix Ephemeris data Transmitted by each satellite, contains important information about the status of the satellite, the current date, and the time. Geodetic system Standard used to indicate locations on the earth. [. . . ]
