Congratulations on your purchase of
the Orion GPS (OGPS).
The OGPS is a compact all-in-one
GPS module solution to connect to a
SynScan computer telescope GoTo
system mounts such as Orion Atlas,
Sirius and SkyView Pro mounts.
The OGPS provides accurate geo-
metrical coordinates and serves as a
precise real-time clock for the GoTo
system.
The receiver continuously tracks all
satellites in view and provides accurate satellite positioning data. The OGPS is
optimized for good performance, low cost, and maximum exibility.

• Orion SynScan GPS mouse (OGPS) with 1.5m cable
with MINIDIN (F) connector
• 50cm adapter cable with MINIDIN (F) connector and RJ-12,

2. Please see the SynScan Hand Controller manual for rmware update
procedure.
3. If the rmware version of the SynScan hand controller is version 3.32 or
later, your hand controller is ready to be connected to OGPS.

5. Plug the RJ-12 connector on the end of the adapter cable into the RJ-12
socket of the SynScan hand controller as shown in Figure 2.

6. Connect DC power (12V):
a. If the hand controller is
connected to the mount, plug
the 12V DC power source
into the mount and press the
mount’s power switch on.
b. If the hand controller is not
connected to the mount, plug
the 12V DC power source
directly into the hand controller.
For instance when in stand-
alone mode, updating hand
controller rmware without
having to attach hand controller to mount.
7. After you power on the hand controller, you will see “Initializing…” displayed
on the LCD for 2 seconds, then the hand control will nd the GPS receiver
module is connected and after press ENTER, the hand control will prompt to
enter the time zone and daylight saving.
8. After setting time zone and daylight saving, the LCD of the hand control will
display blinking text “GPS Fixing…” The rst time you connect the GPS to
the hand controller; it will take at least 50 seconds to x on the GPS signal.
It may take longer, depending on the weather and environment. If it is the
rst time to use the OGPS or it has been more than a week since last time
connecting the OGPS, the time to x current coordinates will take more than
3 minutes.
9. After the OGPS has xed on the GPS signal, the hand controller will display
the version number if the hand controller is connected to the mount, or
the LCD will display “No link to M.C.” and “Stand-alone mode”, if the hand
controller is not connected to the mount.
10. Press ESC, and the hand controller will function as normal. If the GPS
signal is xed successfully, the hand controller will skip the location, date,
and time entry. The date, time, and location will be automatically updated
from the OGPS.
11. In the SynScan hand controller menu, there is a submenu “GPS” under
Utility menu. In this GPS menu, you can read the GPS information. To reach
this menu, press the UTILITY key, then press the scroll keys until “GPS”
appears on the LCD screen. Press ENTER and the hand control will acquire
GPS information within 2 seconds, assuming the OGPS successfully xes
on the GPS signal.
12. When the OGPS xes, “GPS information:” will display on the rst line of the
LCD. You can press the scroll keys to check the GPS information.

The letters (a) to (l) show the display sequence of the GPS Information when you
press the scroll keys.
a. Shows the latitude of the current site.
b. Shows the longitude of the current site.
c. Shows the current date.
d. Shows the current universal time (UT)
e. Shows the current local time (LT)
f. Shows the time zone, which is retrieved from the user-entered data.
g. Shows the current local sidereal time (LST).
h. Shows the altitude of the current site in meters.
i. Shows the received GPS signal quality.
There are 4 levels of GPS signal quality, which are “No x”, “2D”, “3D” and
“3D+DGPS”. The most accurate signal quality is “3D+DGPS”, “3D” is the
second best signal quality, and “2D” is the lowest useable signal quality.
“No x” means that the GPS is currently attempting to x on a signal, or
cannot acquire the signal.
j. Shows the number of GPS satellites which are in the visible sight of the
OGPS.
k. Shows the number of GPS satellites which are currently xed upon by
the OGPS.
l. Shows the magnetic variation (in degrees) of the current observing site.
To leave the “GPS Information” submenu press ESC. The other functions and
operations of the hand controller are unchanged, and are the same as described
in the SynScan Instruction Manual.
