1. System Overview
After entering the desired satellite and polarization the Azimuth, Elevation and Polarization are calculated with the use of GPS information.
Not only the geographical position of the vehicle is determined by the use of GPS, also the direction of the vehicle is calculated with the use of GPS and Glonass* satellites. The GPS/Glonass reception enables the system to calculate the vehicles direction within one-degree accuracy. This accurate direction information combined the extremely precise hybrid motors makes the VPS-X antenna the fastest and most precise antenna on the market.
To accurately measure the position and direction of the vehicle while driving, the Gyro-GPS is supplied with 12-volt supply voltage from the vehicle. When GPS satellite reception is poor, the Gyro System takes over determining the direction of the vehicle. As a backup, the antenna system is also equipped with very precise, chip based, 3-axis, digital compass.
The system communication uses the well-proven CAN-bus protocol, a standard in the automotive industry.
Absolute encoders hold, even with no power to the system, the exact position of the motors. When powered, the motors have a brake-function. For elevation, also an electric brake is incorporated. During a power outage, the antenna can be moved by hand. For elevation movements there is a lever to release the EL-brake. All hand-made movements should be made with care, 5 to 10 degrees/sec at maximum, since manual movements of Hybrid engines generates currents floating through the system, these will be collected by capacitors installed.
Calibration of the system remains intact, even when the antenna is moved with no power on the system. After booting the system, the correct antenna position will be shown.
After start-up of the system, depending on the antenna mode, the user can select a satellite in the “Auto” menu, or press “goto satellite”, if a pre-set satellite is used. A tilt-sensor in the antenna measures the tilt of the vehicle in azimuth, elevation and polarization these values are compensated for when pointing to the satellite. After reaching the calculated position, in most cases immediate reception is available. Lock and EB/No are present. If no lock has been found, an azimuth scan of 2, 4, 16 and 360 degree will be made until lock has been established, during the scan the EL of the antenna will be adjusted if needed.
After carrier identification, the fine-tuning protocol starts. The Eb/No is shown in a graph on the bottom left screen, and will be optimised. After the fine-tune procedure the antenna is ready to transmit.
Depending on the configuration of your system, the antenna controller can be used to control encoders, modulators, amplifiers and baseball switch, all within the powerful the VPS-X Antenna controller.
* Glonass in combination with GPS is standard since 2014, GPS only systems can be updated.

3.10 GPS Menu (1/2)
The GPS Menu shows the calculated Heading by GPS data calculation, as well as the Compass and Manual Heading.
3.10.1
- Connection: Status of Connection from “Touch Terminal” to GPS Heading Calculator in IDU via serial connection on COM1/COM2 auto sensing.
- GPS / Manual: Chose if heading is automatically calculated (GPS) or via Manual input (Manual).
- Digital Compass: Shows current heading calculated by Digital Compass.
- Time Offset: Offset local time to GMT received from GPS Satellite, corrects time shown in the rest of the menu’s of the controller. (Shown in Auto Menu 3.3)
Note: GPS Heading Calculation is only accurate with the antenna is in Stow Position. (Due to Reflections) The VPS Antenna System only reads the GPS Heading once after the system is powered on. If the Antenna is moved, rebooting the Touch Screen controller is needed to refresh heading, or the button “Use GPS for next Motion” needs to be pressed after the correct heading is received, in the GPS Menu 3.10. see above.
If no heading comes automatically via GPS, the system will automatically choose the Digital Compass as AZ reference, as a last option manual heading can be entered. Use compass or smartphone with compass option, to measure the heading of vehicle. Value of heading is related to the front of the antenna, reflector pointing in direction of heading while in stow position. Enter the value manually and activate the value by pressing the “Manual” instead of GPS, followed by “Use for next motion”. Now the system will use the manual heading input.
If the offset of the digital compass is too large, the digital compass can be switched of by de-activating the “Use Compass” checkbox. Recalibrating might be necessary, see document VPS-X Digital Compass Calibration provided by IGP BV.
Did you know? The Keyboard, named Input Panel, can be moved by click/hold and drag the blue bar of the keyboard.

4. User Modes
Basically there are four working modes. Working modes are set in the System Menu see 3.1).
- Radio (IP) Mode, Used for clients that use the same satellite and frequency and lock on their return IP carrier present on Satellite.
- Expert Mode Used for clients that choose their own satellites and frequencies.
- Use Hub Data (with Motors) Users that work fully automated, Pointing, frequency assignment, line-up and Uplink Power Control, with their mobile Uplink system, all controlled via the VPS terminal.
- No Motors- Only Modem Users that work with a non motorized antenna system within the automated VPS mode for frequency assignment, line-up and Uplink Power Control.
4.1
User or Working modes are set in the System Menu, see above right upper corner.
Radio Mode: Nothing checked Expert Mode: Expert Mode checked Use Hub Data(with Motors): Use Hub Data(with Motors) checked No Motors: No Motors checked.

4.1 Radio Mode:
The Radio-Mode shows buttons to directly go to the preset satellite.
Startup screen Radio Mode
4.1.1
Go To Sat: Antenna moves to satellite and fine-tunes antenna, no further action (next screen is 5.1)
Go On Air: Antenna moves to satellite, fine-tunes, and switches IP-modem Tx=On*.(next screen is 5.2) * Assuming a fixed uplink frequency slot.
Screens when antenna is pointed to the satellite
4.1.2 4.1.3
Page 31 of 36
Radio Mode continue,
As can be seen, operating in Radio Mode is very user friendly.
What happens exactly?
After executing antenna movement, the Antenna Controller communicates with the IP-Modem via SNMP, sets the Rx frequency and Symbol rate and controls the Tx On/Off.
The Antenna system waits for the Modem to lock on the “Hub” carrier, after a lock is established, the fine- tune procedure will start, first in Az direction next in EL direction.
The Tx frequency is not set by the Terminal in this mode, set manually!

As soon as the carrier is up, a second Eb/No line is introduced, the thicker line shows the reception value at the receive end. Also the power output of the SNG is controlled by the HUB station, depending on the configuration the HUB station is able to increase or decrease the output level of the SNG to the desired level of operation. The Output power level is controlled during the complete time of transmission.
Stop Tx, will stop transmission after conformation, menu will go back to fig. 4.3.1
