Both systems have different programs. INSEFIS.EXE for system 2 and INS3DM.EXE for system 1. Nevertheless, the programs look more or less identical to the user with the same menus and graphical displays. Below is the software description for system 2. The same description applies to INS3DM. The 3DM and the GPS are connected directly to the QSU-100 in system 1.

Figure 12. Screen dump of system 2's software: INSEFIS.EXE

The software controlling system 2 is divided into 4 modules: (A) main control unit, (B) moving map, (C) camera head gyro display and (D) the about box. The following sections will explain / describe the modules. The arrows from the main menu indicate how to start / show each unit.


Figure 13. INSEFIS.EXE Main module (A).

(1): Main menu with access to PCEFIS's serial settings, remote control, map unit, 3DM display, help / information and the about box. The remote may be enabled / disabled with or without the alarm option. If the remote is enabled and the Auto save checkbox (6) is on, then the log file will be updated in real time. If the remote is enabled, then logging occurs only when the remote switch / camera button is pressed down.

(2): Shows a graphical display of the pitch, roll and yaw angles of the PCEFIS Gyro. Note that with the GPS box checked, then the display uses the track angle of the GPS instead of the yaw from PCEFIS to get the direction of travel (Course).

(3) & (4): Position, speed and directional information from the GPS.

(5): Status bar for PCEFIS communication. The data string starts with the identity tag: PRY. The number and the length of each string are also displayed.

(6): The Log box enables / disables logging of data to disk. See also remarks in (1). The led turns red when recording.

(7): Default serial settings for PCEFIS. COM5 is the first port of the QSU-100. Note that in system 1 the 3DM is connected to COM6 and the GPS is connected to COM5. The baud rates are then set to 9600.

(9): Status bar showing current GPS position in degrees and in UTM coordinates.

Software specification (word) User's guide (pdf) User's guide (word)


a) Align the whole system as recommended in the above user guide.

b) Power up the iPAQ and start the PPCEFISLOG program. If the iPAQ have been powered down too long you might have to transfer the program from the Laptop to the iPAQ. The instructions how to install the software is found in the user guide. If the PPCEFISLOG programs hangs, use the reset button on the iPAQ and start the program once more.

c) Power ON the GPS. Make sure that the GPS talks the NMEA protocol.

d) Turn ON the 3DM gyro. The switch on the forward panel should be set to Battery if not using an external 9 VDC power source.

e) Connect the USB wire from the QSU-100 to the PC and power it up.

f) Connect the remote to the printer port of the PC (LPT1).

g) Wait for the led on the QSU-100 to turn green.

h) Check time: Synchronize clocks on PC, iPAQ and GPS.

i) Start the INSEFIS.EXE program. Make sure that the settings of the serial ports are correct. COM5 for the PCEFIS and COM6 for the 3DM.

j) Use the Align procedure in the PPCEFISLOG program on the iPAQ to initialize the PCEFIS gyro prior to flight.

k) System is now ready. Hint: Remember the auto save option!

Firstly, the QSU-100 software drivers must be installed. These can be located on the net or on the INSEFIS-3DM CD. Just insert the CD into the PC. Then put the USB plug from the instrument into a free USB slot on the PC. Windows will now search for the correct drivers on the CD. It does that a couple of times.

Secondly, double click on the setup.exe which is located on the root of the CD. The files will then be copied over to your local C:\ drive. Just answer Yes to all of the dialogs that pops up.

The software is then installed and ready for use at:

"c:\Gyro\INS3DM\D3\INS3DM.EXE" (System 1)
"c:\Gyro\INSEFIS\D3\INSEFIS.EXE" (System 2)

The Log files are located in subdirectories called "...\D3\Log\". The files are ASCII and are named according to date. Have fun!
