4.3.2. Set Up Observation Site
Scroll down and select “Set up Observ. site”
Press ENTER. The longitude and latitude coordinates will be updated when the GPS picks up
satellite signals. “W/E” means west/east hemisphere; “N/S” means north/south hemisphere; “d” means
degree; “m” means minute; and “s” means second.
If for any reason your GPS can’t pick up a signal you can manually enter the GPS coordinates.
Press ◄ or ► key to move the cursor and using ▲ or ▼ key to toggle between “W” and “E”, “N” and “S”,
using number key to change the numbers. It is always a good idea to do your home work to get the GPS
coordinates before traveling to a new observation site.
The site coordinates information can be found from Support section in iOptron website, under
Controller Set-up (http://www.ioptron.com/support.cfm?module=faq# ).By entering the city name or address,
you can find its latitude and longitude. In case you only find the site information in decimal format you can
convert them into d:m:s format by multiplying the decimal numbers by 60. For example, N47.53 can be
changed to N47º31'48”: 47.53º = 47º +0.53º, 0.53º=0.53x60'=31.8', 0.8'=0.8x60"=48". Therefore,
47.53º=47º31'48" or 47d31m48s.
Press ◄ or ► key, move the cursor to the bottom of the screen to set the time zone information (add
or subtract 60 minutes per time zone). Enter minutes “ahead of” or “behind” UT (universal time).
• Boston is 300 minutes “behind” UT
• Los Angeles is 480 minutes “behind” UT
• Rome is 60 minutes “ahead of” UT
• Beijing is 480 minutes “ahead of” UT
• Sydney is 600 minutes “ahead of” UT
All the time zones in North America are behind UT, as shown in the following table. So make sure it
shows “behind” instead of “ahead of” UT.
Time Zone Hawaii Alaska Pacific Mountain Central Eastern
Hour behind UT -10 -9 -8 -7 -6 -5
Enter Minutes 600 540 480 420 360 300
To adjust minutes, move the cursor to each digit and use the number keys to input number directly.
To change the “behind” or “ahead of” UT, move the cursor to “ahead” and using ▲ or ▼ key to toggle
